Weather synopsis: April 3


12:10pm ample sunshine is upon us into the Northeast with summer like heat into the interior. Record braking heat will continue today with high temperatures in the middle to upper 80's and even approaching the 90°F mark in Buffalo and much of western New York State. In most cases this is warmer than we've been all last summer. This record heat in combination with low relative humidity and strong enough winds are creating ripe conditions for wild fires. The National Weather Service has posted Red Flag Warnings for the potential of brush fires for a good portion of western New York State. Cooler conditions however will be felt along the Atlantic shore into New England, New York City and Long Island where highs will be hard pressed to reach 70°F, though it will still be a gorgeous day weather wise. The cooler temperatures near the coast are due to a maritime air mass and a back door cold front that has developed from the cooler temperatures of the Atlantic Ocean. High Pressure system will keep the sunshine going and prevent any precipitation today. The fair weather will continue through next week. Temperatures wont be as warm as they've been across western New York State and should range between 60°F and 70°F next week with the potential for some isolated thunderstorms; then temperatures will return to normal by next weekend. Along the Atlantic we will be warming it up this week in to the middle 70's with fair weather before temperatures return to normal next weekend.

Weather synopsis: March 31



3:09pm conditions are gradually improving in the Northeast as the storm system we've been dealing with exits the region. This storm system has produced an incredible amounts of rain. Officially 8.88" of rain has been recorded with this system in Suffolk County, NY. 6.18" of rain has been reported in Nassau County, NY and nearly 5.0" of rain elsewhere throughout the Tri-state. With this round of precipitation it will put March 2010 in the record books as the rainiest March on record for much of the New York Metropolitan area. The heavy rain produced a good amount of flooding. The Bronx River Parkway along with a number of other Highways where shutdown in both directions yesterday due to the flooding; in Long Island the high surf combined with the heavy rain produced coastal flooding and a lot of beach erosion; the persistent heavy rains along with 50MPH winds caused trees to topple, a slew of damage due to downed trees and flooded basements have been reported. Thankfully the Northeast is in for a streak of phenomenal weather for the coming days. High temperatures will range between 60°F and 80°F with plenty of sunshine to go along with the mild conditions. This is all due to a High pressure system that will move into the Northeast in the wake of the latest super soaker. The High pressure system will provide plenty of sinking air preventing any large mass of clouds from developing. The air flow will be from south to north and this will usher in the warmer temperatures. Highs will run some 20°F to 30°F above the average. The best weather is expected on our Easter weekend with Highs in the 70's and approaching 80°F in some locations. The fair weather should stick around through the beginning of next week, so go out and enjoy the sun; have a catch and enjoy a nice game of Ultimate Frisbee. This will be perfect weather for the start of Baseball season this weekend as the New York Yankees take on the Boston Redsox at Fenway Park this Sunday. Fair weather is also in the forecast for City Field's home opener as the New York Metropolitans take on the Florida Marlins on Monday.

Weather synopsis: March 30


11:05am portions of the Northeast are being soaked with heavy rain. The rain is attributed to a coastal low pressure system that has developed off the Mid-atlantic. This system will continue its track to the North as the day progresses. Rain will come to an end in the Tri-state area by mid afternoon but clouds will linger through the night. Tomorrow will shape up to be a better day weather wise but we cant rule out the chance for some sprinkles in the morning along the coast. Highs approaching 60°F tomorrow through out the region. Ample sunshine and moderating temperatures are in the forecast. Highs this week will easily approach 70°F making for a picture perfect Easter. NCEP forecast models indicate that this fair weather pattern will continue beyond the weekend.

Monday, March 29, 2010

Weather synopsis: March 29



9:10am the first half of the weekend proved to be spectacular despite the cold temperatures however, the clouds along with the rain has moved in yesterday and it will continue through Tuesday. The Northeast is likely to see chances of rain with the heaviest rain right along the coast. A storm system is working into the region; this system will redevelop off the coast and produce very heavy rain up and down the eastern seaboard with up to 5.0" of rain in the forecast from the Mid-atlantic coast north to the Canadian maritime. Flooding is all ready occurring; wind will will be an issue with a new low developing off shore, no doubt travel will be affected. Once this system pulls away we will experience the best weather of the year thus far. High temperatures will moderate considerably with 60's for Wednesday and 70's by Easter weekend. Expect ample sunshine with those temperatures running some 20° to 30° above normal.

Thursday, March 25, 2010

Weather synopsis: March 25


10:00am after a quick break from the rain on Tuesday yet another storm system moves through the region producing some rain showers. Expect wet weather and chilly temperatures as an associated cold front moves through with the low pressure system. Tonight, expect the rain to mix with and change over to snow in to the interior of the Northeast. Tomorrow, the unsettled weather moves out and cold temperatures moves in. High temperatures will be in the 40's along the coast and in the 30's away from the coast. This weekend is shaping up to be a fair weather weekend with ample sunshine but on the cold side with temperatures in the 30's and 40's. A chance of rain returns Monday and Tuesday then fair weather is in the forecast after. Temperatures next week will star off a little chilly and should moderate by the latter portion of the week.

Monday, March 22, 2010

Weather synopsis: March 22


1:00pm rain is the name of the game across the region as a storm system works into the Northeast. This system continue to produce a steady heavy rain as it re-develops off the coast of New England. This storm comes a week after a super soaker caused rivers and stream to rise above their flood stage. Like the last storm system, this one will produce strong winds to go along with the rain. The rain should come to an end tomorrow. In the wake of this storm sunshine will return however, temperatures will run below average as a sharp quick moving cold front infiltrates the region with high temperatures in the 30's and 40's by early this weekend.

Friday, March 12, 2010

Weather synopsis: March 12


2:50pm our streak of fair weather has come to an end as predicted with a substantial system affecting the Northeast. This storm system will produce flooding rains especially near the coast where up to 4.0" of rain is expected. The heaviest rain will fall Friday into Saturday then tapper off by Sunday. Despite the clouds and heavy rain high temperatures will remain in the 40°F range. Clearing skies will return by Monday and yet another fair weather week is in the forecast. High temperatures next week will range in the 50s with plentiful sunshine. Looking far ahead; NCEP forecast models indicate cooler temperatures will make a comeback with the possibility of wintry precipitation.

Friday, March 5, 2010

Weather synopsis: March 5


1:37pm with the exception of coastal New England, the weather across the Northeast has been spectacular this past week with temperatures running right around average and plenty of sunshine. A pesky low pressure system has been plaguing coastal regions of the Northeast with persistent wind, light rain and snow over the course of the week. This low pressure system should pull away and in its wake some of the best weather of the year so far will move in just in time for the weekend. By the weekend a dry, southerly flow will usher in plenty of sunshine and milder temperatures. This streak of nice weather should reside through the up coming week. High temperatures in Buffalo will hover near the 40°F mark and approaching 50°F towards the latter portion of next week. As of late, there is no significant chance of precipitation for at least another week so enjoy the fair weather as we've had a rough winter this season.

Monday, March 1, 2010

Weather synopsis: March 1


10:15pm the weather is tranquil in the Northeast with light winds and seasonal temperatures. A weak disturbance will produce unsettled conditions Tuesday night into Wednesday with some rain and snow for portions of the region. By the end of this week temperatures will moderate to above average readings. High temperatures will approach 40°F in Buffalo this weekend and approaching 50°F in the Bronx. The upcoming weekend should feature fair weather and above average temperatures, however this stream of good weather will come to an end as another system looms in the horizon for the early portion of next week.

Friday, February 26, 2010

Weather synopsis: February 26


2:00pm a broad area of low pressure is pinwheeling nearly stationary right over the Northeast. This will generate additional snow specifically for the Tri-State area where an additional 10.0" are likely by Saturday morning after receiving about 20.8" of snow officially in Central Park as of 1:00pm this afternoon. Total storm snow accumulations in New York City will range between 20.0" to 30.0" by Saturday morning. This month has broken the all time monthly snowfall record for the month of February in Central Park which was set back in the year 1896 at 30.5", that's a 114 year old record! Else where in to the northern and western suburbs of New York City nearly 40.0" of snow will be common by Saturday morning. Buffalo, NY received around 4.0" to 6.0" of snow however the farther east your go the higher the amounts with 12.0" of snow in Rochester and Syracuse, and about 36.0" in Binghamton, NY. The forecast for the up coming week looks to be more settled. Temperature wise, we will see high temperature readings above freezing for the next few day, this will aid in snow melt but it could lead to urban flooding then re-freezing of melt water at night creating hazardous conditions on untreated surfaces.

Weather synopsis: February 25



12:36pm the gears are in motion as a complex system churns over the Northeast. Snow is falling over much of the region, mostly confined west of the New York State and New England states boarder. The rain/snow line extends south just east of New York City. Through the course of the day however, expect colder air to wrap in to this Nor'easter and change the precipitation to snow into Long Island and parts of New England. The heaviest snow will be confined to northern New Jersey, New York City and then north to Binghamton and locations to the west of the Hudson Valley. Here is where snow accumulations are forecast to top 1 foot and even approach 2 feet around Binghamton. We could end up with 10.0" to 18.0" of snow in New York City with progressively lesser amounts to the east in to Long Island and New England. Heavy snow is expected through out New York State as well. Buffalo, NY should receive up to 10.0" of heavy wet snow with up to 1 foot in to Rochester and Syracuse. Along with the snow, winds will be a factor. the strong forcasted winds combined with heavy wet snow could lead to toppled trees, downed power lines, hundreds of thousands of power-outages and not to mention the high risk of roof collapse. The peak of the storm will occur late this evening in to the over night hours. This system should weaken substantially by Friday however, the upper level low associated with this Nor'easter will meander about through the weekend initiating additional chances of snow through Sunday.

Wednesday, February 24, 2010

Weather synopsis: February 24




12:00pm a slew of Winter Weather advisories have been posted for much of the Northeast by the National Weather Service in anticipation of a Nor'easter that will impact a large area with significant snowfall. This storm will impact regions that have already received mammoth amounts of snow with this month's dynamic weather pattern. Heavy snow is expected on Thursday and Friday with additional snow on Saturday as the storm whinds down. 1 to 2 feet of snow is likely from Philly north up to Binghampton and Albany. As of the current expectations, NYC should miss the brunt of the storm but not after receiving nearly 8.0" of snow. Warmer air over Long Island should keep precipitation mostly in the form of rain. There is still uncertainty with the storm track which could mean the difference between a rain storm in the Tri-state or an accumulation of over 12.0" of snow in to New York City and White Plains. In to southern New England rain will be the issue from coastal Maine down to Boston and Hartford. Heavy snow will spread inland bringing significant snow in to Rochester and Buffalo as well were up to 8.0" of accumulation are likely. Wind will also be an issue most notably near the coast where 40MPH to 50MPH gusts will make for difficult travel.

Tuesday, February 23, 2010

Weather synopsis: Frebruary 23


4:00pm a storm system is moving slowly across the Northeast. This storm features rain near the coast and snow inland with a narrow band of mixed precipitation were a maritime air mass and a arctic air mass meet. This low pressure system produced a dreary day in Buffalo yesterday with a mixed bag of precipitations going back and forth between freezing rain, sleet and snow through the day. This storm system will meander about right through the week over the Northeast. This is anticipated to be a deep low pressure system as it phases with another low pressure system later in the week. Given the nature of the storm system's dynamics, there is uncertainty as to what outcomes might transpire, however at this time there is confidence that a wide spread accumulating snow will affect a good part of the Northeast this week between Thursday and Saturday. At this time, a significant snow event is not out of the question. Behind this system a colder air mass will move in dropping temperatures by some 5°F to 15°F. Elsewhere around the Nation, snow is once again affecting the South in to Dallas, TX where up to 6.0" of accumulations are expected. This is the same storm system that is anticipated to phase with a low pressure system over the Northeast.

Friday, February 19, 2010

Weather synopsis: February 19


3:00pm the weather is tranquil right now but this month has been an active one all around the country. Temperatures in the Northeast are right about average and in some cases slightly above the average. The Lake Effect Snow showers have subsided but not before dumping some 3.0" to 6.0" of snow accumulation in Buffalo this week. A storm system will move into the region early next week and it will bring increased chances of snow in the Northeast from the Great Lakes to the Atlanctic coast. Along with the snow, this system should cool down temperatures by 5°F to 15°F with breezy conditions.

Friday, February 12, 2010

Weather synopsis: February 12


1:48pm this February is proving to be an active weather month across the nation. Another storm system is plaguing the nation, this time southern states are being impacted by heavy rain and snow. A storm system is working its way eastward affecting the Gulf coast with wintry precipitation. This same system produced up to 1 foot of snow in Dallas, TX braking an all time snowfall record there. Even the state of Florida is getting snow. Pensacola, FL should receive up to 1.0" of snow with this round of weather. Cities like New Orleans have been put under a Winter Storm watch for the potential for Snow. Here in the Northeast, yet another storm system will move in bringing additional chances for snow in to New York City, Long Island and Boston. NCEP forecast models indicate a clipper system to move in by Tuesday. There is a potential for up to 6.0" of snow in and around the New York City metropolitan area. Here in Buffalo we will continue to see Lake Effect snow showers for the next few days although no significant accumulations are expected at this time. Temperatures will remain marginally cool so no big arctic air intrusions are expected at this time.

Wednesday, February 10, 2010

Weather synopsis: February 10


9:40pm the blizzard affecting coastal regions of the Northeast is winding down but certainly not after dumping over 1 foot of snow into New York City. Officially 12.0" of snow has been reported in Central Park and 13.0" in the Bronx and another 1.0" to 3.0" inches of additional snow accumulation is expected before the storm completely pull out of the metro area. South of the Tri-state in Philly 15.0" of snow has been reported and over 19.0" of snow reported in Baltimore. To add insult to injury, the winds have been howling near 40MPH creating a blizzard and prolonged white out conditions. This is certainly one for the records as over 100,000 people in 25 States were affected. This is the second storm to affect portions of the Northeast in a matter of just a few days. NCEP forecast models now indicate the potential for yet another storm system of similar proportions to bombard the Northeast with more heavy snow by this up-coming Tuesday! The current persistent storm track of the sub-tropical jet stream combined with a constant flow of cold arctic air by the northern jet stream has created a virtual parade of snow storms aimed at the Northeastern US. It is still too early to accurately predict the impacts of this next round of heavy snow but it is becoming more likely as time progresses that yet another snow storm is on deck.

Tuesday, February 9, 2010

Weather synopsis: February 9



11:09am a Nor'Easter is in the making as two storm systems that have phased together over night in the Ohio River Valley progresses eastward towards the coast. A third low pressure system is forecast to develop off shore of the Long Island coast tonight and then rapidly intensify. This rapid intensification will produce a bonafied blizzard into the New York City metropolitan area where 1 to 2 feet of snow is likely along with strong winds over 40MPH. This combination of heavy wet snow and strong winds will likely cause power outages and topple down some trees especially near the coast where winds will blow more fierce. Visibilities will drop to zero and produce white out conditions for a prolonged period during the height of the storm. The worst weather will hit the tri-state region right around Noon time and then progress through the early afternoon. Though it will be below freezing some sleet will mix in at times into eastern Long Island as the storm's intensity churns the atmosphere above. Winter Storm Warnings are in effect until 6am on Thursday when the storm finally pulls out of the region. NCEP forecast models indicate that this storm will develop a dry slot, if this is the case it will lessen snowfall totals though a significant amount is still expected regardless. Impact from this storm will be felt from the Great Lakes down to the Mid-atlantic and up to southern New England. The worst of the weather will come with the development of the coast storm that will produce the strong winds from D.C. to Boston.

Monday, February 8, 2010

Weather synopsis: February 8



11:20am a historic Nor'easter has hammered portions of the Mid-atlantic last weekend dumping up to 3 feet of snow in locations in and around the Philly, Baltimore and Washington D.C. corridor. Thankfully this storm strayed away from southern New England and Long Island where only a few snow flurries were reported however, next time we might not be so lucky. NCEP forecast models predict another storm system of similar proportions to develop off the Mid-atlantic coast then move up the eastern seaboard all the while rapidly intensifying into a Nor'easter. This storm will likely impact the Washington D.C. region once again with heavy amounts of snow. This coastal storm will move northward bringing heavy snow to New York City, Long Island and southern New England including Hartford, Providence and Boston. This storm system will also have an impact into western New York and interior Pennsylvania where Winter Storm Watches have been issued. Even Buffalo will get an accumulating snow out of this storm. Though it is still too early to make an accurate snowfall forecast, the heaviest amounts of snow will be along the I-95 corridor from D.C. to Boston including the states of Maryland, Delaware, New Jersey, eastern Pennsylvanian, southern New York, Connecticut, Rhode Island and eastern Massachusetts. This is the most densely populated section of the country and millions of people will be affected by this storm. The current time frame is as follows: Snow will begin by Tuesday in the western fringes including Buffalo, NY then work its way east. The storm will then re-develop off the coast and intensify Tuesday night into Wednesday with the brunt of the storm into New York City and Long Island between midnight Tuesday and midnight Wednesday

Thursday, February 4, 2010

Weather synopsis: February 4


11.00am the weather in the Northeast is being dominated by a High Pressure system. This system is providing fair weather. This is the calm before the storm as I expect this area of High Pressure to give way to a storm system tomorrow that will likely produce pretty heavy snowfall for the Mid-atlantic and southern New England. The storm system should re-develop over the Atlantic Ocean and transcend into a full blown Nor'easter. 1-2 feet of snow is not out of the question from Long Island down to the Delmarva peninsula including the big cities like New York, Philadelphia, Baltimore and Washington D.C. The heaviest snow should fall right along the coast. This storm system will produce snowfall rates of up to 3.0" per hour at times. In NYC the snow will likely start Friday evening around 9:00pm and continue through the Noon time hour on Saturday. This storm system is due in part to an El Niño weather pattern with a storm track aimed at the Northeast. NCEP forecast models hint towards a continuation of this storm track, if that is the case I expect this month to be an active weather month for the region.

Monday, February 1, 2010

Weather synopsis: February 1


3:15pm temperatures in the Northeast are bearable ranging between mid 30s along the coast, mid 20s in the interior and 10s into Norther New England. These temperatures are rather seasonal for this time of year and should stick around trhough the week. Tomorrow light Lake Effect Snow showers could redevelop but this wont be as impressive as last weeks snow. Tonight clouds will increase and snow flurries will develop late. The chance for snow will increase into the afternoon hours tomorrow and continue into the evening in Buffalo. Winds will be light and any snow that does fall will not amount to much, maybe less than an inch of snow. Tomorrow is Ground Hog's Day and we'll see if we have another 6 weeks of winter or an early spring to look forward to.

Friday, January 29, 2010

Weather synopsis: January 29


7:00pm temperatures through out the Northeast have been cold to say the least. Temperatures have been in the 0s to 10s with wind chill values much colder. Expect more of the same temperature wise as this stubborn air mass lingers tomorrow and into our Saturday. After Sunday we can expect moderating temperatures, though it will still be cold it wont be nearly as cold as its been. This past week in Buffalo over 1 foot of snow has fallen with the latest round of Lake Effect Snow. Regions to the south are also expecting some significant snowfall as well as moderate icing. Looking forward, Lake Effect Snow will likely re-develop sometime this up coming week producing additional amounts of snow across Western New York.

Thursday, January 28, 2010

Weather synopsis: January 28


12:30pm a cold sharp front associated with a clipper system is working its way through the Northeast. Temperatures ahead of the front are in the 30's, behind this frontal boundary temperatures have taken a significant plunge with current readings in the 10's in Buffalo. Expect falling temperatures through the day as this round of arctic air settles in over the Northeast. Bone chilling cold will be felt for the next few days. Along with the low temperatures winds will also be an issue essentially making it feel much colder than it is. Winds should gust up and over 40MPH. Wind chill values will be well below zero in most cases. This cold front is also creating enough instability to produce wide spread snow showers across the region. Reports from NYC of up to 1.0" of snow have been observed with another inch not out of the question by day's end. Over the Great Lakes the passage of this cold front has re-oriented the winds over the lakes producing more Lake Effect snow over the lee-ward side of the lakes. Total Lake Effect snow accumulations in and around Buffalo should amount between 7.0" to 16.0" by the time the Lake Effect activity tappers off this Saturday.

Wednesday, January 27, 2010

Weather synopsis: January 27



10:50am temperatures in the Northeast range between the mid 20's across the eastern Great Lakes and mid 30's along the coast. There is a Lake Effect Snow Advisory in effect for the city of Buffalo as a southwesterly wind over Lake Erie is producing moderate snow showers. Additional snow accumulations by days end could range between 4.0" to 7.0". These Lake Effect snow bands will develop south of Buffalo and work their way north to Niagara Falls. The heaviest snowfall amounts will be in the most persistent squalls. Lake Effect snow is forecast to redevelop for the remainder of the work week as the wind orientation will be right off the Lakes with another round of significant snow on Thursday likely. Winds are forecast to change course by Friday, the Lake Erie snow machine will cease, total snow accumulations for the week will range between 6.0" to 12.0" with some locations picking up more than that. Temperature wise, extreme cold will be felt across much of the Northeast as the thick of the current arctic air mass moves in from Canada. High temperatures forecast from Thursday through Saturday will be in the 10's and 20's in the Northeast with lows below Zero to the 10's, when you factor in the wind it will fell much colder so bundle up. NCEP forecast models have hinted towards a potential coastal Low Pressure System affect the Major cities along the coast this weekend, as of now the forecast models predict a blocking High Pressure System that should veer the coastal low to the south into the Mid-atlantic. This should spare the big cities like New York and Boston from a potential Nor'Easter,

Tuesday, January 26, 2010

Weather synopsis: January 26



2:20pm temperatures in the Northeast are divided by a cold front that is working its way on eastward. Ahead of the front temperatures are in the 40's with the last rements of this week's the storm system taking its final toll. Behind the front temperatures arein the 20's and 30's with Lake Effect snow showers off Lakes Erie and Ontario. Locations east of Lake Ontario near Watertown could pick up between 6.0" and 12.0" of snow with in the next 24hrs. Locations downwind of Lake Erie will pick up an additional 1.0" to 3.0" of snow including the city of Buffalo. South of Buffalo up to 6.0" of additional snow accumulations are in the forecast as those Lake Effect snow bands could be more presistant. A chance for Lake Effect snow will linger through much of the week across the eastern Great Lakes with a presistant cold wind. NCEP forecast models agree that this cold pattern will carry on for the foreseeable future with a storm system likely impacting the coastal regions of the Northeast especially NYC and Long Island with significant snow and wind by this weekend.

Monday, January 25, 2010

Weather synopsis: January 25


7:20pm the storm system that produced the heavy rain in the region is moving away. This storm has produce impressive rainfall with 2.20" reported in Erie County. Flood warnings were issued with the rain combined with melting snow causing water levels to rise. In the wake of the storm, temperatures began to drop steadily as time progressed. The forecast temperatures will continue to drop through the week as an arctic air mass continues to settle in. By the end of the work week High temperatures should top off in the middle to upper 10's across Western New York. Winds are expected to change directions and will be oriented off Lakes Erie and Ontario. This will produce Lake Effect snow showers. Locally 1.0" to 3.0" of snow can be expected with higher amounts into Syracuse and locations south of Buffalo. By the end of the work week yet another storm system will make its way into the Northeast. Primarily coastal regions will be impacted as this will be more of a coastal storm. With cold temperatures in the forecast we could be dealing with snow along the major cities from Boston to New York and farther south into the Mid-atlantic into Washington D.C. and Philladelphia this Friday and Saturday.

Sunday, January 24, 2010

Weather synopsis: January 24


10:40pm the weather across much of the eastern third of the nation has been rather soggy to say the least. A rather dynamic storm system has taken the place of the High pressure system that produced the fair weather on Friday and Saturday across much of the Northeast. Flood advisories have been issued up and down the eastern sea board where heavy amounts of rain is being observed and can be expected to continue. Regionally forecast rainfall could very well range between 1.0" across the interior to 3.0" along the coast. South of the region the heavy rain could be accompanied with some embedded thunderstorms, some of which could produce severe weather and locally heavier amounts of rain. The rainfall is forecast to dissipate from west to east across the region on Monday. This storm system is currently dragging a sharp cold front and with its passage temperatures will plummet through out the course of the week as an arctic air mass settles in. As the storm system pulls away and temperatures drop, wind orientation across the Great Lakes have the potential to produce lake effects snow showers for a good portion of the week. This arctic air mass combined with the current progressive weather pattern could yield a snowier time period ahead. NCEP forecast models seem to agree as data seems correlate with colder temperatures for the days ahead.

Friday, January 22, 2010

Weather synopsis: January 22-25


At 1:20am temperatures in the Northeastern U.S. are pretty chilly but still above average ranging generally between 10's in the interior to low 30's along the coast. Temperatures continue to oscillate between seasonable conditions and mild temperatures as the jet-stream reconfigures itself producing a dynamic weather pattern. The weather in the Northeast is being dominated by High Pressure creating sinking air and a chillier night relatively speaking. This High Pressure system will act as a blocking mechanism as it should divert a storm system that is moving up from the South and steer it clear from the region. As the High Pressure system progresses eastward, its clockwise flow will shift winds from the south again, re-introducing mild temperatures into the region. A storm system will move in from the west and likely impact the region by the latter half of the weekend. With mild temperatures in place rain will be on tap. With the recent Arctic Cold invasion and some areas still covered in snow combined with mild temperatures and heavy rain this situation will likely create flooding. Rain should continue through Monday. Behind this system temperatures will likely take a tumble. Looking ahead, NCEP forecast models suggest another period of bitter cold so don't put away the Arctic gear just yet, we've only entered the thick of the season and old man winter always has tricks up his sleeves.

Tuesday, January 19, 2010

Weather synopsis: January 18


At midnight the temperature in Bronx County, NY is 43°F under mostly cloudy skies. The rain storm that has impacted the region this past Sunday has produced a considerable amount of rain and wind. Rainfall amounts have been recorded over 0.5" in NYC to greater than 1.5" over Long Island combined with a melting snow pack causing some flooding. Considerable wind gusts have also been reported ranging between 40MPH in the Bronx to over 50MPH at Shinnecock inlet in Long Island. Unseasonably mild conditions continue after weeks of bone chilling cold, we reached a high temperature of 50°F today. Temperatures are running some 15° to 20° above the average for January standards. Climatologically speaking, these mild temperatures aren't that unusual as it is typical to see a prolonged period of mild temperatures in the month of January within the contiguous United States. This phenomenon is known as the January Thaw. These mild conditions however will likely be short lived as we are only entering the thick of the Winter season. A cold front will sweep the region tomorrow and drop our temperatures to more seasonable readings tho not nearly as cold as we've experienced thus far this Winter season. This cold front has the potential to initiate a few light snow showers within the region Tuesday night and Wednesday morning, I want to emphasize the word light; any precipitation that does fall shouldn't have any considerable impact on any event plans or travel arrangements. Looking ahead, temperatures will likely oscillate between cold and mild readings for the foreseeable future. The next real chance for any considerable precipitation will arrive by the weeks end. A storm system will likely impact the region on Friday the 22nd through Saturday the 23rd with a mix of Rain and Snow as temperatures will run right on the precipice of supporting frozen and liquid precipitation. Looking far ahead, NCEP forecast models are predicting a colder pattern to return to the region with the possibility of a storm system impacting the Northeast region near Ground Hog's Day. I want to mention that a forecast this far into the future is subject to change as weather, especially this time of year; is dynamic and virtually unpredictable even with the most sophisticated forecasting equipment and super computer calculations.

Saturday, January 16, 2010

Weather synopsis: January 16


Currently in the Bronx the temperature is 42°F under mostly clear skies. High temperatures today should hit 50°F as our warm streak continues. A storm system over the Gulf of Mexico will be moving northward to our region by Sunday the 17th. This low pressure system will feature heavy rain and strong winds. The low should move out by Tuesday and in its wake colder temperatures should move in. On Wednesday a clipper system will move in from Canada and has the potential to produce steady snow showers.

Weather synopsis: January 15


At 9:19am the temperature in the Bronx is 38°F with an overcast sky. Warm weather has infiltrated the region with high temperatures returning to the 40's. This temperature rebound is the result of a shift in the weather pattern that will allow the subtropical jet-stream to bring milder conditions. A storm system brewing over the Gulf of Mexico will initiate heavy rain an possible severe thunderstorms for the Southeast this week then it will begin to work its way northward up the east coast sometime this weekend into early next week. With warmer temperatures influencing our weather the precipitation will likely fall in the form of rain for the most part and it could be heavy at times. In the wake of this system a cold front will drop temperatures by Tuesday 19th.
