“An intensifying and fast moving storm will bring rain for tonight,” said the National Weather Service in a tweet.

That would be moving in from southwest to northeast by around midnight and winding down by around noon Saturday, said Gary Conte, weather service meteorologist based in Upton.

Around three-quarters to an inch of rain, possibly higher in some spots, is in the forecast from 7 p.m. Friday to 1 p.m. Saturday, the weather service said.

A “quick shot of rain is coming our way,” News 12 Long Island meteorologist Rich Hoffman.

Look for breezy conditions Saturday, with dry skies in the afternoon and highs in the upper 40s, Conte said.

Highs dip down to the upper 30s for Sunday, which also brings the chance for flurries, then snow showers after midnight into Monday morning. This is expected to be just a dusting, Conte said, with no significant accumulation anticipated.

Speaking of Monday, you might want to plan on bundling up, as highs dip down to the upper 20s.
