The unseasonably warm weather over the weekend is forecast to come to a wintry end Monday as a snowstorm is expected to sweep over Long Island on Monday night into Tuesday.

Don't expect to do much shoveling, though, as the National Weather Service predicts no more than an inch and a half of powder.

If the storm drifts further south over New York, however, there is a chance that it could bring as much as 4 or 5 inches in some parts of Nassau and Suffolk counties. The last time Long Island saw 3 inches of snow was on Feb. 13, 2022, according to Dominic Ramunni, a weather service meteorologist in Upton.

The mercury is expected to rise to about 48 degrees during the day Sunday and dip to around 32 in the evening, both under cloudy skies.

The average high temperature for this time of year is 40 degrees, according to Ramunni, who added the entire month of February has been warmer than average.

The temperature Saturday topped out at 55 degrees in Islip at 3:41 p.m.

Monday will feature some sun during the day and a high of 46 before dropping to about 34 degrees. An area of low pressure emerging off the Atlantic coast late Monday night into Tuesday is expected to bring cold air from the north and could drop rain that changes to snow, Ramunni said.

Gov. Kathy Hochul called on state residents to prepare for a storm that could bring heavy snow, gusty winds, moderate coastal flooding and potentially dangerous driving conditions.

The weather service issued a winter storm watch for northern Westchester County and Putnam and Rockland counties, as well as inland Connecticut and northeast New Jersey. Snow accumulations in those areas late Monday night through Tuesday afternoon could be 6 to 8 inches with 10 inches possible at higher elevations. 

Although it is too early to predict how much snow will stick on Long Island, it might be the time “to get those plows out and give them something to do this season,” Ramunni said.

He noted that Tuesday has the “potential for the largest snowfall in a couple of seasons — at least on Islip.”
