Significant Winter Storm Expected Across Parts of NY and New England

For the most part, this will just be a nuisance type storm with snow changing to rain. Most will only see a Trace to perhaps as much as 3" across the higher terrain. Across parts of Upstate NY into Northern New England, this event will produce a moderate to locally heavy snowfall, with highest amounts across the mountains. We have capped the snowfall at a maximum of 10", which will be possible across Adirondacks of New York, Green/White mountains of Vermont, and the Foothills of Northern New Hampshire and Maine.

We have highlighted several areas where locally heavier amounts are possible. Most of this area is in responses to the expected wrap-around and Lake Effect/Enhancement from Lakes Erie and Ontario on the backside of that Low Pressure. The region across North Central PA and the Northern Pocono mountains are where local amounts of up to 3" could be found from the intial wave of snow. Elsewhere, downwind of Lakes Erie and Ontario could potentially see some moderate to locally heavy amounts of snow, particularly the mountains of Northwestern Pennsylvania and the Chatauqua Ridge of Western New York. Concerning Lake Ontario... expect Oswego, Oneida, Lewis, and southern Jefferson counties will be under the gun for this event, with locally in excess of 1 foot possible.

We do expect a Lake Effect Event to setup during the day late Thursday into most of Friday, however this forecast package extends only thru Midnight Friday. Therefore, the projected accumulations are only meant to capture the early going enhancement before any significant Lake Effect Plumes set in.
