Some late season snow is in the forecast for late Thursday into Friday, with the Friday morning commute expected to be impacted.

Forecasters are also watching another system that could affect the area late Monday into Tuesday.

Though the Friday system’s track and timing could shift with later computer model runs, as of Wednesday evening the expectation was for precipitation to start as rain Thursday night, with a rain snow mix, and pretty much pure snow in Friday’s early morning hours, said John Murray, National Weather Service meteorologist, based in Upton.

That means morning commuters would be confronting slippery conditions on untreated roads, he said.

Snow is expected to be diminishing in the afternoon hours, he said.

In all, an average of 3 to 4 inches are forecast for most of the Island, with slightly higher amounts possible for the East End.

Still, that could shift with the Upton office’s next major forecast update, based on computer models run in the overnight hours, he said. That update comes out around 4 a.m. Thursday.

As snowfall wraps up later Friday, look for Arctic air to rush into the region, said Jay Engle, also a weather service meteorologist in Upton. Given gusty winds, temperatures early morning Saturday could feel like the single digits, even near zero in some areas, he said.

The next chance for snow is for Monday night into Tuesday, and “computer models are showing a potentially more significant snow next Tuesday, but that is way too far in the future to get into specifics,” said Bill Korbel, News 12 Long Island meteorologist.

As for more winter-esque temperatures, the weather service says to look for colder than normal temperatures continuing into early next week.
