After a clear Wednesday night, rain is expected to arrive and stop before dawn, likely ushering in a day of dropping temperatures and strong winds, the National Weather Service said.
The weather service issued a wind advisory for the entire region from 9 a.m. to 7 p.m. Thursday with sustained northwest winds of 20 to 30 mph and gusts of between 45 and 50 mph. Winds are predicted to increase through the day and the service warned it could result in downed trees.
Temperatures will reach the high 40s Thursday morning, but then drop throughout the day to below freezing with wind chills of between 10 and 15 degrees. The high Friday will be just 29 degrees, the service said, and temperatures in the teens are expected Friday night into Saturday, when partly sunny skies are expected to give way to snow and freezing rain.
Meanwhile, a gale warning will be in effect from 7 a.m. Thursday until 1 p.m. Friday for Long Island waters, the weather service warned. Included in the warning are the Long Island Sound, as well as South Shore bays from New York Harbor and Jones Inlet all the way to Montauk Point.
The weather service is calling for seas of five to eight feet in ocean waters and three to six feet on the Sound. Wind gusts in excess of 50 mph are expected.
