HUDSON VALLEY, NY — The first of two back-to-back winter storms is likely to bring wet snow to the region to kick off the weekend. The National Weather Service has issued winter weather advisories in effect from 6 p.m. to 10 a.m. Saturday.

For Orange, Putnam, Rockland and Westchester counties, the NWS predicts total snow accumulations of 3 to 5 inches with locally higher amounts up to near 6 inches on higher elevations, especially in Orange County near and northwest of Interstate 84.

For Dutchess and eastern Ulster, total snow accumulations of 2 to 5 inches, greatest across higher elevations.

Hudson Valley Weather is predicting 4-6 inches of snow could accumulate in parts of Orange and northwestern Rockland counties and even in Dutchess and Putnam. "Highest probability of heavy snowfall amounts are west of the river, and higher terrain facing east or south, such as Hudson Highlands and Eastern Cats. Lowest amounts - southernmost Westchester and Rockland Counties, areas along and east of the river," said Alex Marra.

There's also a potential for minor coastal flooding along western Long Island Sound.

The storm is likely to begin as rain, and then transition to wintry mix and snow around the New York City metro area.

Snowfall rates of up to 3/4 inch per hour are possible from 10 p.m. to 9 a.m., the National Weather Service said.

Still, temperatures above freezing mean low-elevation locations in southern New York are likely to have mainly wet roads, even at night, said AccuWeather Senior Meteorologist Joe Lundberg. "But snow-covered roads are much more likely a few hundred feet higher up over the hills and mountains."

Meteorologists are already looking past the weekend toward another storm system that could become a nor-easter by Monday.

If it hugs the mid-Atlantic coast, then mountainous regions from the Poconos to the Catskills and Berkshires could be "in the thick of the heavy snow," Lundberg said. Gusty winds, storm tides and flooding could also be in the mix.

After Saturday's snow, temps will be in the high 30s during the day and below freezing at night, so there will be a little time for any snow that accumulates overnight Friday to melt before more arrives Monday into Tuesday.
