11:11pm a powerful storm system will plow through the region on Friday, this system will produce heavy rain and strong winds gusting over 40 miles per hour along the coast with heavy snow further inland. Snowfall rates of up to 2" per hour are likely over western New York State during the height of the storm between 7:00am through 2:00pm. Snow accumulations will range between 4" to as much as one foot in Buffalo. Along with the heavy snow, winds gusting to 35 miles per hour will drop visibilities to around a 1/4 mile or less producing white out conditions. During this same time frame, heavy rain will affect the Atlantic coast. Combined with a deep snow pack, rain could create issues of urban and small stream flooding. Strong winds will also be an issue. Wind gust of up to 60 miles per hour could knock down trees and cause wide spread damage. Precipitation will subside in the evening.

Weather synopsis: Monday February 21


8:35pm The extended forecast calls for a continuation of the cold weather this week, forecast highs will be in the 20s and 30s through out the week - though it will be cold, a High Pressure system will produce clear skies thus the higher angle of the sun as we come closer towards spring will produce a brilliant sunshine during the daytime through the middle of the week. High temperatures will reach the 40s on Thursday. Then another storm system will be in the works late in the week. The cyclone genesis of this storm is yet to be determined - nevertheless, this next system may bring more Ice, snow and wind to the Northeast late this week on Friday and Saturday.

12:14pm a winter storm will affect the Northeast tonight and tomorrow. This storm system will produce a heavy snowfall across interior portions of the Northeast this evening into Monday morning - snow will mix with rain and sleet along the coast on Monday limiting snow accumulations. 3-6" of snow is possible in Buffalo by Monday Morning with lesser amounts as you head towards the Atlantic seaboard ~2-5" expected in and around New York City. The extended forecast calls for a continuation of the cold weather this week, forecast highs will be in the 20s and 30s through out the week - though it will be cold, a High Pressure system will produce clear skies thus the higher angle of the sun as we come closer towards spring will produce a brilliant sunshine during the daytime through the middle of the week. High temperatures will reach the 40s on Thursday. Then another storm system will be in the works late in the week.

Weather synopsis: February 11 & 14


இڿ­ڰۣ-ڰۣ—Happy-Valentines-Dayஇڿ­ڰۣ-ڰۣ—
11:11am needless to say, it's been a bone chilling cold week thanks to this latest intrusion of arctic air. Temperatures remained between 10-20° below where we should be this time of the year. Along with the frigid temperatures, winds inexcess of 40 miles per hour made it feel well below zero. There is good news for the winter weary - finally there is a warm up on the way after Valentines Day. First we have to get through another clipper system that produced more light snow over the Great Lakes and Northern New England - this clipper will keep the cold temperatures around for a time but not for long. A mass of relatively warmer air will advance northward this upcoming week that will expel northward the dense cold air mass which has gripped the Northeast for the better part of this winter. This week our temperatures will climb into the 30s and 40s early next week in the Northeast with 50s and 60s or better not out of the question during the latter portion of the week; it is definitely going to feel like spring. Look, I'm not saying that we are done with winter, keep in mind - it's only mid-February, there is still one more month of Winter to contend with. Nevertheless, the prolonged cold spell of below average temperatures over the Northeast will fall apart - temperatures over the next several weeks will oscillate between alternating cold and warm periods. I guess the groundhog - Punxsutawney Phil was right, spring might make an early entrance, but keep in mind - it's only mid-February. Historically speaking, late February and early March are notorious for big Northeast winter storms. Enjoy the warmth but don't put away the shovels and snow melts just yet.

Weather synopsis: Saturday February 5


5:08pm more rain and snow will continue through the evening. The greatest accumulations will be associated with an upper level low pressure system moving over the Northeast this evening changing rain back to snow, an additional 2-4 inches is likely across western New York - little to no accumulations expected along the coast. A wicked cold arctic air mass will visit the Northeast this week that could set the stage for another storm along the coast - forecast models are in disagreement in regards to the cyclone genesis and track of this potential storm system late next week but one thing is almost certain, it will be cold. Temperatures will bottom out once again this week as frigid air streams into the region on Monday and Tuesday lasting through the week, single digit cold and subzero lows are likely with this next invasion of arctic air. Good news for those starked by old man winter, long range temperature projections indicate that a warm air mass with above average temperatures my try to push into the Northeast for a time after Valentines Day.

12:44pm another storm is in the forecast for the Northeast on Saturday. This storm will move northeastward and produce a swath of precipitation - predominantly closer to the coast. Light rain, snow and sleet will fall through the day on Saturday in New York City with light snow further inland. Snow flurries could make it all the way in to Buffalo with little to no accumulations. Then, the upper level low feature associated with this storm will produce a light, but steadier snowfall during the late evening hours on Saturday over New York City. Snowfall totals should be minimal between 1-4 inches. After this weekend's storm, two more storms will affect the Northeast, the latter of which could turn into a big Nor'Easter late next week. Temperatures will actually moderate by a few degrees early in the week - then another arctic air mass will infiltrate the region behind a cold front on Tuesday, this will set the stage for the potential Nor'Easter later on during the week. It is too early to forecast the precise impact this system will have on the Northeast, however; forecast models are indicating a strengthening system moving up the eastern sea board around the Thursday time frame.

10:05am our big winter storm is still amongst us however, the bark was bigger than the bite. The storm system began to break apart this morning during the time that the heaviest precipitation was forecast to fall. Additionally, sleet and snow pellets began to mix in with the snow as a temperature inversion aloft allowed warmer air to come in to the upper atmosphere with temperatures below freezing at the surface. Snow accumulations have ranged between 3" and 6" in and around the grater Buffalo area with another 1-2 inches on the way towards the afternoon hours. Up to 2" of snow and nearly 1/2 inch of ice has fallen over New York City, now the precipitation has changed to plain rain causing concerns of street flooding as we get some melting of the snow pack. I hate to sound like a broken record but another storm is on the way for this weekend, this next system looks like it will be a coastal storm. The exact track this storm will take as it rides up the coast is uncertain at this point but it does appear as if warmer air will be involved with this system right along the coast with cold air staying further inland. More details will be made available as we approach the weekend. Today is Groundhog Day and the famous Punxsutawney Phil did not see his shadow predicting an early end to the winter and early arrival of Spring.
