Long Island Weather Forecast Includes Freeze Watch

Long Island may soon see its first frost as temperatures are locally forecast to dip below freezing overnight at least one night this week, threatening crops and possibly ending the growing season.

A freeze watch is in effect 10 p.m. Tuesday to 10 a.m. Wednesday, when temps are expected to drop to a low of 26 overnight across Nassau and Suffolk counties, as well as parts of New York City and New Jersey, according to the Upton-based National Weather Service meteorologists.

A freeze watch means below freezing temperatures are possible. An NWS forecaster said a recent freeze warning on LI did cause some frost, but it was not widespread and didn’t last long.

The watch comes as Veterans Day hit the 50s with a 50-percent chance of light rain overnight into Tuesday morning, when temps may reach a high of 45 before potentially dropping down below the freezing mark overnight.

The forecast calls for sunny skies for the rest of the week, hitting a high of 42 Wednesday but dropping down to a low of 32 at night.

Temps will remain in the 50s during the day and hover around the high 30s to mid 40s after sundown through the weekend.

If the forecast proves accurate, the first frost will be right on schedule, where it usually comes after Nov. 10 on western LI and as early as mid to late October on parts of Suffolk’s South Shore and East End.
