While the area will have cold, windy “hold onto your hats” weather for Tuesday, according to the National Weather Service’s Upton office, forecasters are also focused on the potential for a significant nor’easter Friday night into Saturday.

Thanks to blustery winds, Tuesday’s “feels-like” temperatures could be in the single digits to teens, said Kevin Kacan, weather service meteorologist based in Upton. That will be followed by mostly dry and cold conditions the rest of the week.

But, looking at elements, including a low pressure area still in the Pacific, “widespread snow is becoming more likely from this storm system for Friday and Saturday for the eastern U.S.,” said the National Oceanic and Atmospheric Administration’s Weather Prediction Center in a Facebook post.

The impact on Long Island, though, depends on factors such as track and timing, and it’s just too early to pin them down with much certainty, Kacan said. Depending on the track, the range for the Island includes “a very significant event with heavy snowfall,” to “a lot of rainfall,” to even just a fairly dry day, should the system take a turn out to sea, he said.

News 12 Long Island meteorologist Rich Hoffman advises to “be alert” to changes to the forecast, and “If the storm is on the maps Wednesday morning — start finding the shovels.”

That’s because one scenario, the weather service said, could mean “significant snowfall,” high winds and coastal flooding, with an added dimension of Friday night being just one day shy of a full moon.
