Long Island weather: Rain, mild temps through Wednesday

Rain was making its way into the region but the heavier showers are due to come down in the evening, overnight and into Wednesday, the National Weather Service said.

Gusty winds and mild temperatures will accompany the system with highs in the mid- to upper 50s Tuesday through Thursday. But daytime readings will start to slide back into the upper 40s on Friday, and nighttime lows will drop to around freezing.

“Toward afternoon steady rain will attempt to work in from the west, but much of this steadier rain is likely to hold off until the evening further west and closer to midnight further east,” the weather service said.

There is a 90% chance of rain Wednesday, and another half an inch of precipitation might fall, bringing the two-day total about an inch and a half, forecasters said. Those chances then decline to 60% that night, and there is only a slight chance of showers after 8 p.m.

“Drier and noticeably cooler (air) begins to work in late at night and towards daybreak as temperatures fall back mainly into and through the 40s,” the weather service predicted.

Look for mostly sunny skies Thursday and Friday, as a cloud-erasing high pressure weather pattern will briefly nose in from north of the metropolitan area, the weather service said.

North winds could gust up to 25 mph, a lingering effect of that departed frontal system.

And it could be quite chilly in some spots on Thursday night: “Lows will fall below freezing north and northwest with upper 20s in some spots, and 30s elsewhere,” the forecasters said.

Rain could return Friday night — the odds are 30% after 8 p.m. — and Saturday could also be damp, with a 30% chance during the day and through Sunday.

Friday will be partly sunny but temperatures that day and the weekend will be more seasonable, with daytime highs in the high 40s and lows hovering around the freezing mark.

Only rain is predicted for most of the tristate area but the state's interior could see light snow.

Monday’s should be at least partly sunny. The forecasters said: “High temperatures will be at or below normal through the weekend, with a slight warmup expected … early next week."
