Yesterday we had our first taste of cold weather for the season, with temperatures dropping down into the low 30s for much of the state! A cold weather pattern is swingingin for most of the week from Canada, and we will see the chance for spotty rain showers, and even the slight possibility for flurries in the Litchfield hills.
A low pressure system lies over Southern Canada, and a warm front extends east across Northern New England. An amplifying upper level jet at 250 mb will strengthen this system, but pull it northeast and away from New England for Saturday. Following the passage of this system, a major dip in the jet stream will advect cold, dry air down from Canada. This will dictate our weather for next week mainly, with temperatures staying below average and cool. This northwest flow will remain until next weekend, where we will see a building ridge and a chance for temperatures to climb to seasonal again.
High pressure over the mid-Atlantic moves offshore, and daytime heating will keep temperatures around seasonal. By tonight clouds will build in ahead of the approaching cold front from the associated low in Canada.
A cold front approaches from the west, and scattered showers will pass through during the day tomorrow. Following the passage of the cold front, a secondary weaker front will pass through and begin our cold weather for the week. Temperatures should climb to the low 60s, but plunge overnight following the passage of the secondary front.
A northwesterly flow and high pressure building to our south will make for brisk temperatures and some windy conditions for Sunday. With this weather pattern in place, afternoon flurries and snow showers are common for upstate NY, particularly in the mountains. Now depending on how far southeast these scattered snow showers come, I cannot completely rule out passing flurries or isolated snow showers for the extreme northwestern portion of the state. It is a slight chance we could see the first flakes of the season, but I wouldn’t bet everything on it. Temperatures will be below seasonal in the upper 40s, and skies will improve throughout the day.
Monday – Tuesday
Monday looks cool, with temperatures in the upper 40s and lower 50s. Afternoon clouds may develop and move through, but besides that expect a mostly sunny day. Tuesday though is more interesting. A weak clipper system looks to pass through, and with temperatures in the 50s, the chance for snow is ruled out. But, there will be a chance for an afternoon passing shower.
Wednesday – Friday
An upper level ridge and the building of high pressure will make for a nice end to the work week. Temperatures will remain cool in the upper 40s and lower 50s for this time, and by Friday the northwesterly flow that will have dominated our weather will move out, and be replaced with a more zonal flow.
Friday: Sunny becoming cloudy. Highs in the 50s.
Saturday: Cloudy. Chance for showers 50%. Highs in the lower 60s.
Sunday: Cloudy becoming mostly sunny. Highs in the upper 40s. Breezy.
Monday: Cool. Mostly sunny. Highs in the upper 40s and lower 50s.
Tuesday: Mostly sunny with afternoon clouds and a passing shower. Highs in the 50s.
Wednesday: Mostly sunny. Highs in the lower 50s.
Thursday: Partly sunny. Highs in the lower 50s.
