Long Islanders should prepare for a little rain overnight, as the expectation is for scattered showers and thunderstorms, starting in the late evening, forecasters say.

That’s as the Storm Prediction Center is indicating a marginal risk for severe thunderstorms in neighboring areas — including eastern Pennsylvania and the lower Hudson Valley — with the prime threat being from damaging winds.

Arrivals are being affected at area airports, with average delays of an hour and three quarters for Kennedy and just over an hour for LaGuardia, according to the Federal Aviation Administration website. Departures, too, could be affected.

A line of storms stretching from northern New York down to central Pennsylvania — with a second line behind that one — is impacting flights, said Faye Morrone, a National Weather Service meteorologist based in Upton.

In addition, a high risk of rip currents continues for Atlantic Ocean beaches through 9 p.m. Tuesday, the weather service said.

Chances for showers and thunderstorms were at 50 percent for overnight Tuesday — lessening to around 30 percent for Wednesday, mostly through around noon, the weather service said.

Temperatures Wednesday are forecast for the low to mid-80s, similar to Tuesday’s, but with lower humidity, Morrone said.

“Nice weather into the weekend,” said Rich Hoffman, News 12 Long Island meteorologist.

The rest of the week should be sunny with high temperatures in the mid- to upper 70s, the weather service said.
