Snow Accumulating in Nanuet's Weekend Forecast

NANUET, NY — We all know that weather can change fast. This week's a good example: On Monday, meteorologists predicted a 30 percent chance of snow for the weekend. Wednesday, they were all in agreement that the much discussed potential-first-accumulating snow of the season wouldn't happen.

Now they're forecasting 2-4 inches in the lower Hudson Valley.

The short version: while waves of Arctic air continue in from Canada as expected, the Atlantic storm making its way up the East Coast got more organized and shifted its track westward.

The National Weather Service put a Winter Weather Advisory out for Putnam, Rockland and Westchester counties:

6 AM SATURDAY TO 1 AM EST SUNDAY

WHAT...Snow expected. Plan on hazardous travel conditions. Total snow accumulations of 2 to 4 inches are expected.

WHERE...Portions of northeast New Jersey and southeast New York.

WHEN...From 6 AM Saturday to 1 AM EST Sunday. Highest snow accumulation should occur Saturday morning into Saturday evening.

ADDITIONAL DETAILS...Be prepared for reduced visibilities at times.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Weather Advisory for snow means periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use caution while driving. The latest road conditions for the state you are calling from can be obtained by calling 5 1 1.
