An active pattern developing as we move straight from one winter weather event to the next. A low pressure will push northeast into the Great Lakes on Wednesday, and it will bring another round of wintry weather to the Hudson Valley.
– Snow develops between 10am and 2pm Wednesday
– Snow falls steady/heavy late PM early evening
– Snow changes to sleet then rain before ending near/after midnight.
Preliminary Snow Accumulations (Subject to change):
– Catskills: 4 to 8 inches
– Mid & Upper Hudson Valley: 2 to 6 inches
– Lower Hudson Valley (south of I-84): 1 to 3 inches
Cold air will be in place ahead of this storm, so we’ll all start off as snow. However another storm track where a low pressure moving into the Great Lakes will bring enough warm air in the mid layers of the atmosphere to cause the snow to transition to a wintry mix, and then rain (likely between 7pm and 10pm), before tapering off after midnight as the low pressure pushes the precipitation to our northeast.
Temperatures are projected to be in the upper 20s to around 30° when the snow moves in, and should begin to accumulate on all surfaces. In addition, the timing of the snow arrival appears to be late morning. This will cause have impacts on travel, so school cancellations or early releases appear likely on Wednesday.
In terms of accumulations, this system has the potential to spread a blanket of 2 to 6 inches of snow over a wide area. Highest totals will be in the higher elevations like the Catskills and Taconics, where it will take longest to transition to rain. But much of the valley could see several inches of snow as well. Unfortunately for snow lovers, this system is very likely to transition to rain before ending late Wednesday night.
We will iron out the details on Tuesday, prior to issuing the formal storm forecast Tuesday evening, but signs of winter are finally appearing in the Hudson Valley.
