Hurricane Season 2010 Update: July 1


The first named storm of the Atlantic Hurricane Season made landfall in northern Mexico approximately 100 miles south of Brownsville, Texas. Hurricane Alex made landfall as a Category 2 Hurricane with the strongest winds near its center of circulation measured at 100 MPH. Its minimum central pressure was measured at 947 Millibars making Hurricane Alex the strongest Hurricane to form in the Atlantic basin since Hurricane Dolly in 1994. Hurricane Alex formed from a tropical wave that made its way across the Atlantic Ocean. When it reached the Caribbean Sea it brought torrential downpours to Puerto Rico, The Dominican Republic, Haiti, Jamaica and Cuba. The tropical wave slowly churned the waters of the Caribbean Sea until it developed a closed circulation surface Low Pressure. It was the dubbed Tropical Depression 1 and it began to slowly move west towards Mexico and Belize. The system intensified in to a Tropical Storm and it made landfall over the Yucatan Peninsula. The Tropical Storm brought flooding rains to Honduras, Belize and Mexico' Yucatan. Over land, the system weakened to a Tropical Depression however, Alex moved into the open waters of the Gulf of Mexico an quickly restrengthened to Tropical Storm status then Hurricane status making it the first Hurricane to form in the Atlantic since 1994. Hurricane Alex produced storm surge, torrential rains, damaging winds and spawned Tornadoes over south Texas. Now over land once again, Alex will continue to weaken and eventually dissipate however the remains of this system will continue producing heavy rain over south Texas then eventually over the Midwest.

Weather synopsis: June 8


4:20pm it has been a rather cool start to the work week for the most part across the Northeast. A storm system has pulled out of the region and in its wake a cool and dry air mass has moved in. High temperatures have been generally in the upper 50's to lower 70's with lows down in to the upper 40's in upstate New York and upper 50's along the coast. A new storm system will move infiltrate the region Wednesday; expect increasing clouds tonight in western New York with rain showers for tomorrow. The heaviest rain should remain south of Buffalo in to the Ohio River Valley; this storm system will progress east towards the coast and produce a steady rain fall for Pennsylvania then eventually the Hudson River Valley and southern New England. The rain will likely cease by early Thursday morning in the New York City metropolitan area. In the wake of this next system, temperatures should rebound nicely by Friday and down right hot by the weekend. A slight chance of showers and storms in the forecast in to the weekend with the greatest risk of storms likely on Sunday.

Weather synopsis: June 6




4:09pm a vigorous low pressure system is charging through the region. This storm system is dragging an sharp cold front. Ahead of the front temperatures are in the 90°F range; behind the front temperatures are in the 50°F range. This sharp difference in temperature is indicative of a very unstable atmosphere over the region. This instability has produced impressive amounts of rain over western New York yesterday with strong storms that have spawned a deadly Tornado outbreak over the Ohio River Valley and portions of the Midwest. Now this same system is plowing east towards the coast; Tornado watches have been posted from down east Maine to Washington D.C. Wind gusts of up to 80MPH are likely as a squall line of storms race eastward. Along with the damaging wind potential these storms could also produce golf ball sized hail and frequent cloud to ground lightning. Doppler radar indicate that these storms have been loosing strength, however portions of southern New England could still receive some severe thunder storms. Once this storm system pulls away expect a stretch of fair weather through the work week. Monday should be dry with cooler temperatures ranging between 65°F and 75°F. Temperatures will moderate this week but should remain around average with ample sunshine.

Weather synopsis: May 25


5:41pm although technically not a heatwave, it will certainly feel that way across the entire region these next few days. A High Pressure system will usher in a hot and humid air mass to influence the eastern two thirds of the Nation. The Northeast will experience temperatures some 15° to 25° above the average for this time of year. Temperatures will range between 85°F and 95°F from Buffalo, NY to Bangor, Maine and down the coast from Boston to New York and Washington D.C. Long range forecast models indicate this pattern wont last long, by this Friday temperatures should return to the 70s which is more typical and more bearable for late May. The high heat will produce enough instability in the Atmosphere that will likely trigger some strong to severe thunder storms Wednesday evening. Highs on Wednesday will reach 90°F or better for most of the region. Word of advise, wear plenty of Sunscreen to protect your skin from harmful Ultraviolet radiation from the Sun. Every time you get sunburned you increase your chances of skin cancer by a significant factor. Also, keep your self hydrated; drink plenty of water and avoid excessive alcoholic beverages.

Tuesday, May 4, 2010

Weather synopsis: May 4

10:25am wide spread showers with a slight chance of a thunderstorm today. Highs in to the upper 60s and low 70s for the Northeast. Warming up tomorrow warming up to the upper 70s and low 80s for the entire region with plenty of sunshine.

Saturday, April 24, 2010

Weather synopsis: April 24


10:41am an area of High Pressure will give way to a Low Pressure System moving from the South to the Northeast. This system will feature moderate to heavy rain for the Northeast. The Southeast has been receiving strong to severe thunderstorms capable of spawning Tornadoes that will stay well south of the Northeast. The forecast for the Northeast region calls for nice weather today with temperatures in the mid 60s. Increasing clouds can be expected through the evening ahead of the Low Pressure System. Rain will break out in the early morning tomorrow and will continue at a moderate rate. Looking ahead, rain will continue through the early week. Rain should cease by Tuesday in upstate New York but will linger into Wednesday along the Atlantic coast. Temperatures will go on a roller-coaster ride; ahead of this Low Pressure System temperatures will be on the warm side in the 60s, behind the system temperatures will be some 10° cooler in the 50s, then by Wednesday and Thursday temperatures will warm up once more. NCEP forecast models suggest that another big warm up is in the works for the latter portion of the week with temperatures possibly approaching record levels.

Tuesday, April 20, 2010

Weather synopsis: April 20


4:20pm beautiful spring weather continues over much of the Northeast. Hardly any clouds in the sky today in Buffalo, NY and for a good portion of the region. A weak Low Pressure system will try and push in from the south but the region remains under the influence of a dense High Pressure air mass preventing any heavy precipitation if any. The Low Pressure System will produce partly cloudy skies tonight with a very slight chance of a shower tonight especially for southern portions of the Northeast region. Fair weather will be likely through the week and much of the weekend. The average temperature trends and fair weather will stick around till Sunday afternoon-ish. A new Low Pressure System currently affecting the Pacific coast will progress east-bound, affecting much of the Nation before moving in to the Northeast. Current NCEP forecast model projections suggest that the unsettled weather should arrive during the early evening hours this Sunday. Looking far ahead, NCEP forecast models indicate this next Low Pressure System might be a slow mover;if this is indeed the case we can expect a more soggy forecast for next week.

Monday, April 19, 2010

Weather synonpsis: April 19


1:17pm typical spring like conditions prevail over the region. Almanac records indicate that our temperatures are running right around the average for the date. Plenty of sunshine today with just a slight brisk in the air of a spring day. Temperatures are running between 50° and 60° Fahrenheit in upstate New York with a temperature spread between 60°F and 70°F along the Atlantic coast. The forecast calls for this trend to continue through the week as a High Pressure system will take precedence over the Northeast. This system will produce an air mass of stable dense sinking air, this should prevent any showers or mass cumulus cloud formations.

Monday, April 12, 2010

Weather synopsis: April 12


7:11pm typical spring weather will continue this week across the Northeast. High temperatures this week will range between 55°F-60°F in upstate New York and New England and up to 70°F in the southern portion of the region in to southern New York and Pennsylvania. There is a slight chance of light rain Tuesday with a better chance of rain on the horizon into the up coming weekend. NCEP forecast models indicate a prominent storm system will move south from Canada and initiate rain showers in western New York on Thursday. The rain should spread east in to southern New York by Friday. Heavy rain is likely this weekend in the Tri-state area with the storm system redeveloping of shore. Behind the storm system a period of slightly cooler temperatures is possible.

Thursday, April 8, 2010

Weather synopsis: April 8



11:32am beautiful weather is in the forecast for most of the day, temperatures will climb in to the 50s and 60s north of a stationary front and in to the 70s and 80s to the south. Partly to mostly cloudy skies today with increasing clouds by evening. The increasing clouds are due to an approaching cold front to our west that is associated with an upper level low pressure system. Behind this front temperatures will be much cooler but right around normal. Temperatures have been well above average lately for much of the region. A stationary front extended from the Midwest to the Northeast, this was the same front that produced the train of stormy weather and cool temperatures in Buffalo, NY most of the week. South of the front temperatures reached record levels. Yesterday New York City reached 92°F making April 6 the earliest 90° day on record in Central Park; its hard to believe that just 6 weeks ago we were buried in 2 feet of snow. The dry heat sparked concerns of wild brush fires; the National Weather Service posted advisories that placed much of the Northeast under Red Flag Warnings. Though not quite as hot today, New York City will approach 80°F; the same can be expected for much of the region south of the stationary front. The big cheese today will be the passage of a cold front that will spark some showers and introduce a cooler air mass for the entire region. The front will intrude from west to east. It will reach western New York State early this evening then work its way east towards the Atlantic Ocean. Highs on Friday will be in the 30s in northern New England, 40s in Upstate New York and 50s along the coast. Beyond Friday the Northeast will be under the influence of a High Pressure system that will produce pleasant spring weather this weekend and most of next week.

Wednesday, April 7, 2010

Weather synopsis: April7




12:37pm it was a stormy scene in Buffalo, NY this morning as severe thunderstorms spawned large hail as they rumbled through town. The weather across the Northeast will be divided by a frontal boundary. To the north of this front expect cool temperatures with the chance of showers and storms. South of this front expect summer like heat with temperatures approaching 90°F with ample sunshine. The high heat combined with low relative humidity south of the frontal boundary has raised concerns for wild fires. For this reason, the National Weather Service has posted Fire Weather Warnings for much of the Northeast and Midatlantic. Expect much of the same conditions through Thursday before a cold front sweeps the region and drops our temperatures to where they should be this time of year. The weekend is looking to be sunny and dry but cooler with pleasant Spring time temperatures.

Tuesday, April 6, 2010

Weather synopsis: April 6


11:03am scattered showers and thunderstorms have been rumbling through the Northeast this morning. A stationary front over the Great Lakes has provided a means for a series of weak disturbances to move from the Midwest into the Northeast. Some of these disturbances will feature some embedded thunderstorms; some of which could be strong to severe. Temperatures to the north of the stationary front will be slightly cooler in to the 50s and 60s compared to the 70s south of the front. This frontal boundary is associated with a more potent storm system over the nation's mid section that will likely produce severe weather in the Midwest today before working its way to the Northeast as the week progresses. This storm system will drag a cold front that will eventually drop our temperatures by the end of the week by a significant factor. Highs are forecast to be in the 40s and 50s by Friday with a chance of rain mixing with snow at night in to the higher elevations. Tomorrow will be a nice day with highs reaching the 70s and warmer south of the frontal boundary with 80's. These warm temperatures will likely cause enough instability in the Atmosphere to produce isolated spring time thunderstorms. Thursday will be a trancision day as a cold front works in from the west. Generally speaking; expect temperatures to remain mild to warm with a slight chance of scattered showers and storms then cooler and by the end of the week. This weekend wont be a complete washout as sunshine returns by Saturday afternoon and highs returning to the 60s. Fair weather should continue beyond Sunday with a chance of showers returning next week Wednesday.

Saturday, April 3, 2010

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.

Tuesday, March 30, 2010

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.

Thursday, February 25, 2010

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.
