Hudson Valley Forecast: Wind Chill Warning this Weekend, Snow Possible Monday

The National Weather Service early Saturday made it official: a Wind Chill Warning is now in effect for all of Westchester as well as Putnam and Rockland counties, today and into Sunday.

“The Hudson Valley is in store for an ugly day on Saturday,” said Bill Potter of Hudson Valley Weather.

The Sound shore had been under a “Wind Chill Watch,” which was upgraded to a warning Saturday morning -- and the time frame expanded to earlier Saturday afternoon.

• Wind Chill Warning in effect from February 13, 01:00 PM EST until February 14, 12:00 PM EST
• Special Weather Statement
• Hazardous Weather Outlook

Around midnight the region is expected to be below zero and falling into Sunday morning, and wind chill factors could make it feel as cold as 25 to 30 below. The “warmer” parts of the area will only feel like 15 degrees below zero.

Then, once the extreme cold snaps on Monday, we could be looking at some snow, turning to sleet, and then heavy rain on Tuesday.

The National Weather Service already has issued a “Hazardous Weather Outlook” for Monday night saying “significant wintry precipitation” may hit us -- but the track of the storm is causing a lot of uncertainty.

No snow accumulation estimates have been made.

“In a winter full of complicated storms, and difficult forecasts… why would we expect anything different this time?” Potter said.

Snow should break out across the Hudson Valley sometime Monday -- but whether it will start in the late morning or hold till the evening is uncertain.

Even more uncertain is what will happen next. The computer models vary, predicting anything from low snowfall, short period of icing, then warming and heavy rain -- or more snow, more icing, less rain.
