UPDATED: Friday 3:15pm
The Friday morning computer data has come in… and the consensus is that the Hudson Valley will just miss out on another Spring snow event…
A wave of low pressure will ride along an arctic boundary, and spread a rather narrow band of moderate to heavy snow as it does. A day or two ago… it appeared like that band of heavy snow would pass right over the Hudson Valley. Now… that boundary looks like it’s about 50 miles further south… and that should be enough to take the accumulating snow, just to our south.
The image above demonstrates where the general consensus is at this point. The heavy snow should stay in NE PA, and northern NJ. Our area could see some light snow showers, and flurries… but at this point in the season, if it’s not snowing hard… anything that falls, will melt on contact. So while a period of light snow showers can’t be ruled out in our area… it would likely melt as it falls, and temperatures could even climb above 40° in many parts of the area.
It is worth noting… and can be seen by looking at the map above… that the smallest of shift north, could pull the accumulating snow up into Orange, Rockland, and Westchester counties. We can’t completely rule that out at this point… but it must be stated, that we can’t find a single piece of data that supports that idea right now. Should this change… we’ll be sure to pass it along. But right now… it looks like the accumulation, stays south of the Hudson Valley…
Original Post below:
The cold front has passed through the region, in its wake are much cooler temps compared to yesterday. We still have a good bit of instability in its wake thanks to an upper level feature. This will allow some pop up showers and areas of grauple through the afternoon hours. Highs today should longer in the upper 40’s to low 50’s, with lows trending back below freezing with lows around 30. A NW flow will begin to take hold across the region in the wake of the cold front and a negative trough in the NE corridor will allow even colder air to filter in for the weekend. Both Sat and Sun lows will also look to dip below freezing across the region.
We have also been monitoring the possibility for an area of low pressure to develop along this negative trough Saturday. Exactly where this low pressure forms and how far north it can track are not completely clear at the moment, but the trend has been to keep it a bit further south. This would keep the bulk of any Frozen precip that falls to our south. Some light snow is possible Saturday evening with the probability being highest across the higher elevations and some of the southern counties. We will continue to monitor today’s data for more clarity and adjust forecast as needed. Best bet is no matter how you slice it, Saturday and Sunday will not feel very much like April, some snow is possible. Please check back with us later today for more updates.
