Update: Tarrytown, Sleepy Hollow Could Be Facing a Major Snow, Ice Storm This Weekend

Updated at 5:13 p.m. on Wednesday, Jan. 21, 2015: The National Weather Service has revised its forecast from this morning, and it’s definitely not good news for Tarrytown and Sleepy Hollow residents.

According to the latest National Weather Service update issued Wednesday afternoon, a coastal storm Saturday and Saturday night could result in either a significant snowfall across the Hudson Valley, or significant icing across the region.

And here’s the kicker, there remains a high level of uncertainty with regards to the track of the low and this will greatly impact the type and amount of precipitation.

The National Weather Service says snow could start after 3 a.m. Saturday morning, and then rain, snow, and ice will fall throughout Saturday and into Saturday night. Snow could accumulate up to 3 inches along with an ice accumulation. The likelihood of the precipitation is at 70 percent currently.

Snow is expected to end around midnight.

Forecasters are keeping a close eye on a potential weekend nor’easter that could dump more than a half-foot of snow on Westchester and the Hudson Valley.

The National Weather Service issued a hazardous weather outlook for the entire region early Wednesday.

“Unlike many storms this winter, this particular one has the potential to bring a foot of snow to some locations, where rain fails to mix in,” according to AccuWeather.com Chief Meteorologist Elliot Abrams.

However, the exact strength of the storm is unknown, due in part to the final track it will take.

“There is uncertainty and the precipitation in terms of amount and type will be highly dependent on the strength and exact track of the low [pressure system],” the NWS said in the hazardous weather outlook.

The current forecast calls for increasing chances of snow across the entire region going into Saturday and continuing into Saturday evening before tapering off late at night. The nor’easter could result in snow accumulations ”in excess of 6 inches,” the NWS says.

Before the potential winter whopper, the Hudson Valley will likely get a small taste of snow on Wednesday night, with up to a 70 percent chance of precipitation, the NWS says.
