Long Island weather: Some more sun but rain coming

Long Island should get some more sun Friday but forecasters say rain is coming.

The National Weather Service on Thursday evening was predicting it will be partly sunny Friday with a high temperature near 66 degrees and a northeast wind of about 11 mph.

But Friday night into early Saturday morning there is a 40% chance of rain after 2 a.m.

Saturday rain is likely, with thunderstorms possible after 2 p.m. The chance of precipitation is 70%.

"Cloud cover with rain chances persist for much of the extended period, as the remnant Ian likely lingers to the south of the region,” the weather service, referring to now-Tropical Storm Ian, said Thursday morning.

The New York region can plan for what the weather service calls “a period of long duration, but light rainfall this weekend into early next week.”

The arrival of clouds is due to a rain-creating low-pressure system developing to the south that will incorporate remnants of Tropical Storm Ian, now pummeling Florida with catastrophic and life-threatening floods and powerful winds clocked at around 65 mph, according to the weather service and the National Hurricane Center.

Ian should have exited Florida but by Friday afternoon or evening, it could have made landfall for a second time on the South Carolina coast, the forecasters said.

Easterly breezes, the weather service said, could cause the sea to rise enough to reach “minor coastal flood benchmarks around times of high tides, mainly across the South Shore bays and the coastline of Long Island Sound along Westchester and southwest Connecticut.”

On Sunday, the precipitation chances slip to 40%, and Monday should be at least partly sunny and breezy, though the rain may return that night.

The rainfall odds are 30% Monday night and Tuesday.

The skies should clear by Wednesday, as a weak high pressure system arrives from the Ohio Valley.
