Thursday should see highs in the mid-40s, but it will also usher in a shot of cold air — call it bundle-up weather — for Friday, Saturday and Sunday, forecasters say.

After Thursday’s overnight lows in the upper 20s, Friday should bring highs in the upper 30s on Long Island, slipping down to the mid-20s for most areas overnight, according to the National Weather Service.

It’s a shot of the coldest air so far this season, said Faye Barthold, a weather service meteorologist based in Upton.

Overnight Thursday into Friday brings a 20 percent chance of snow showers or flurries as a cold front passes through, Barthold said. Accumulation would probably not be in the picture, she said, other than a possible quick coating with any heavier shower.

Friday is also expected to be on the breezy side, so wind chill will be in play, making temperatures feel even cooler.

As of Wednesday’s forecast, Saturday’s high is expected to reach the mid-30s, with overnight lows mostly in the mid-20s.

Sunday may be looking at a small bounce-back, with highs in the lower 40s, and Monday is expected to head back up to highs in the upper 40s, she said.

But don’t get too used to that, as forecasters are watching computer models that are pointing to a second cold blast.

“A pattern change seems to be underway that will bring much colder weather” to the area by the middle to end of next week, said Bill Korbel, News 12 Long Island meteorologist.

Temperatures could “perhaps be as much as 10 degrees below normal for a few days,” he said.

The normal high at Long Island MacArthur Airport in the period would be 42 to 43 degrees, Barthold said, with lows of 27 to 29.
