LI Snow Update: See What's Ahead For The Weekend's Next Blast Of Winter

LONG ISLAND, NY — Long Islanders should expect the possibility of some snow this weekend — but so far, forecasters say accumulation may not be as significant as last weekend's storm.

According to Joe Pollina, meteorologist with the National Weather Service: "We're looking at a 30 to 40 percent chance of snow for western to central Long Island for Sunday morning. It could start Saturday night, but the peak of the storm for us is Sunday morning. There's about a 50 to 60 percent chance for eastern Long Island," he said.

Projected snowfall amounts are currently only available through Saturday night until 7 a.m. Sunday, when about an inch of snow or less is expected for much of Long Island, he said.

The barrier islands and the South Fork, including Montauk, could receive about 1.2 inches by 7 a.m. Sunday, Pollina added.

Snowfall estimates for the rest of Sunday should be available closer to the storm, Pollina said.

Chances of precipitation decrease late Sunday morning into Sunday afternoon and evening, Pollina said.

He added that there is still a great deal of uncertainty about the forecast, with the model likely to change later on Thursday.

Temperatures are expected to remain cold: On Thursday across Long Island, a cold weather advisory remains in effect until 10 a.m. Friday, with wind chills as low as minus 6 degrees. Cold wind chills could result in hypothermia if precautions are not taken, Suffolk County officials said, urging residents to wear appropriate clothing when heading outside.

Highs on Sunday will only in the 20s, Pollina said.

According to a release from AccuWeather, the "bitterly cold Arctic air will stay locked in across much of the eastern half of the U.S., complicating storm cleanup efforts and keeping energy demand elevated."

And, AccuWeather said, as the storm intensifies Friday night into Saturday in the southeastern states, strong winds and rising seas will push water onshore from North Carolina to New England, producing coastal flooding and beach erosion.

“Beach erosion is one of the hidden hazards of powerful winter coastal storms. When waves repeatedly crash against the shore on top of elevated water levels, dunes can be carved away and protective berms can vanish, leaving communities more exposed to future storms," AccuWeather Senior Meteorologist Scott Homan said. “With a full moon this weekend, astronomical tides will be higher than normal. That means even a modest storm surge can push water much farther inland than people expect. Coastal residents need to be prepared for flooding near high tide.”
