An Arctic air mass will push temperatures on Long Island into the teens or lower later this week, according to the National Weather Service.

Sunday will see a chance of scattered flurries before 1 p.m., with partly sunny skies and highs in the upper 30s to near 40, said Joe Pollina, meteorologist with the service's Upton bureau. It will be breezy, with southwest winds from 13 to 20 mph.

Sunday night will be partly cloudy, with lows in the upper 20s to low 30s.

Monday will again be partly sunny, with highs in the lower 40s. The clouds will return Monday night, with lows in the mid-20s for much of Long Island, and in the teens in eastern Suffolk and the pine barrens, Pollina said.

The Arctic cold moves in on Tuesday, bringing with it a chance of scattered flurries before noon, with a 20 percent chance of snow showers. Mostly cloudy skies will prevail, with highs in the mid-20s.

A polar vortex earlier this month pushed temperatures into the teens and single digits, with the windchill making it feel below freezing. Pollina said that this week's cold weather was simply an Arctic air mass pushing into the area.

The 20 percent chance of precipitation will continue Tuesday night, with lows in the single digits to around 10, Pollina said.

Wednesday will be mostly sunny, but highs will reach only into the upper teens. Wednesday night lows will be in the teens, with single digits possible in the pine barrens.

Thursday will see a 30 percent chance of snow, with highs in the mid-20s. Lows on Thursday will be in the teens, with mostly cloudy skies and a continued 30 percent chance of snow showers.

Friday will be mostly sunny, with highs in the mid- to upper 20s. Friday night will be mostly cloudy, with lows in the teens.

By Saturday, the region will warm up slightly, into the middle 30s.

"It's still slightly below normal for this time of year, but a little better than what Friday will be," Pollina said.
