Freeze Warning is in effect from Midnight Monday night to 9am Tuesday

Tonight: Temperatures will drop into the mid-30s across Long Island. It likely won’t freeze in most spots, but a frost advisory is in effect for Suffolk County, meaning sensitive plants could still be damaged. If you’ve started gardening, it’s a good idea to cover or bring plants inside overnight.

Monday: It will stay on the cool side, with highs in the upper 40s to low 50s. A passing shower is possible, but much of the day will just feel brisk with a mix of clouds and sun.

Monday night: Another chilly night is expected, but temperatures may drop to near freezing for parts of Long Island. Even so, patchy frost is possible and even a freeze in colder spots, so it’s worth protecting plants again.

Midweek into next weekend: A warm-up begins Tuesday, with a more noticeable jump in temperatures by Wednesday and Thursday when highs reach the 60s. By Friday and into next weekend, cooler air may return along with a slight chance of rain.
