Snow likely Sunday on Long Island, with East End getting up to 4 inches, NWS says

Long Islanders can expect their next significant snowfall on Sunday morning, the National Weather Service said. 

The agency is tracking two low-pressure systems that will bring snow across the state. From Friday night through Saturday, the first system will bring the "most significant snowfall" in the Lower Hudson Valley, meteorologist Sam Lankowicz with the weather service's Upton office, told Newsday on Friday afternoon.

That region, as well as northeast New Jersey, could see 2 to 4 inches of snow, according to a Friday afternoon weather service briefing.

While the weather service has forecast a chance of snow for Long Island overnight Friday through Saturday morning, "if there's anything" falling on the Island during this first wave, "it's not anything really significant," Lankowicz said.

"For Long Island, what we're looking at is the second system on Sunday," she added.

The weather service has forecast a chance of rain across Long Island for Saturday evening. Between early Sunday morning through Sunday evening, most of Long Island will receive around a half-inch to 1½ inches of snow, Lankowicz said. The East End could receive 2 to 4 inches of snow.

"It looks like midmorning into the afternoon is when it's really going to pick up for the Island," Lankowicz said.

Between heavier snowfalls last month and a few less-than-an-inch hits in January, more than 13 inches of snow have been recorded in Islip so far this season, according to NWS records.

Saturday highs are expected to reach the low- to mid-40s before temperatures drop around 10 degrees at night. Sunday highs will peak just below 40 degrees.

The sun is expected to shine on Monday, Martin Luther King Jr. Day, when temperatures will reach the mid-30s. Temps will drop into the low 20s on Tuesday, according to the weather service.
