Long Islanders out early on the final day of 2025 will find it cold, dry and partly sunny, but by the time one year ends and another begins, there could be fresh snow on the ground with more on the way.
The high Wednesday, New Year’s Eve, will hit about 35 degrees, with winds of between 10 and 13 mph, and occasional gusts as high as 23 mph, making if feel closer to between 15 and 23 degrees, according to the National Weather Service.
Clouds are forecast to thicken by Wednesday evening with a low of 24 and the chance of snow rising to 70% by 1 a.m. Thursday, the weather service forecast Tuesday.
"We've got snow starting as early as 7 p.m. [Wednesday] ... but it's going to be most likely between midnight and 7 a.m. [Thursday]," meteorologist James Tomasini with the weather service's Upton office told Newsday Tuesday evening. "We're looking at totals around an inch for Suffolk County on average."
The East End will see closer to 1.5 inches of snow, while Nassau County and western Suffolk will receive closer to a half-inch, Tomasini added.
High and low temperatures on New Year’s Eve, New Year’s Day and through the weekend are forecast to be 5 to 10 degrees below normal, according to Tomasini.
"The normal highs are usually in the lower 40s and the normal lows are usually in the upper 20s," the meteorologist added.

In some areas of Nassau and Suffolk, including Bayville and Baiting Hollow, gusts blew at 60 mph early Tuesday. The island's strongest early morning gust, 69 mph, was measured in Stony Brook.
Winds could gust up to 25 mph Wednesday evening, "nothing that is expected to be too impactful," Tomasini said.
