A hazardous weather outlook has been issued for Suffolk County east of the William Floyd Parkway, as there's a chance that a nor'easter expected to develop Saturday night to the southeast of Montauk Point could track closer to the coast, according to the National Weather Service.
As of Friday morning, "the chance for a significant snowfall is low" late Saturday into Sunday, the weather outlook said, but that could change if the storm's course shifts.
Still, a shift that would lead to significantly heavy snowfall is becoming less likely, said Tim Morrin, weather service meteorologist based in Upton.
Snowfall on Long Island is expected to be 1 to possibly 4 inches, he said, with the higher end of the range forecast for eastern Suffolk, this from late in the day to early evening Saturday through late morning Sunday.
As a prelude to that weather event, mixed rain and snow turning to all snow is expected to start Friday night close to midnight, ending by late morning Saturday, this with minor accumulation, he said. Precipitation is expected to be light, "and I will underline light," he said.
As for Sunday, prepare for a blast of bitter cold, he said, with temperatures in the 20s made to feel chiller -- in the single digits -- by winds picking up from the north-northwest. Monday is expected to be more seasonable, he said.
