Several pockets of heavier rain embedded in Thursday afternoon's thunderstorms, accompanied by strong, gusty winds, moved quickly through parts of Long Island, forecasters said.

As of shortly before 4 p.m., no damage related to the short-lived squalls had been reported, said Jay Engle, National Weather Service meteorologist based in Upton.

Showers moving in from the south and west mean that evening commuters in parts of Suffolk County could be impacted by brief, heavy rainfall and gusty winds, the weather service said.

A dense fog advisory is in effect through midnight, warning of quarter-mile or less visibility at times, the weather service said, meaning hazardous travel conditions.

There's the potential for isolated, heavy downpours through around midnight, said Brian Ciemnecki, National Weather Service meteorologist in Upton, along with possible thunderstorms.

While the showers linger until late morning Friday, the warm air stays only a short time, pushed out by a cold front from the south, said the service's Upton office.

Daily highs in the low 50s are expected Thursday across Nassau and Suffolk counties; by Friday cold air settles in, dropping daily highs for the weekend by 10 degrees or more, the service said.

Along with the splash of warmth Thursday comes winds from the south, increasing to 12 mph to 17 mph by the afternoon, the service said.

News 12 Long Island meteorologist Rich Hoffman called for a "brief break in the cold air" Thursday, also with daily highs in the 50s.

Hoffman said showers and a threat of thunderstorms dominate the Thursday outlook, "before a cold front passes Long Island around midnight."

Daily highs Friday are expected to be in the mid 40s before slipping to the high 30s Saturday and low 40s Sunday.

The service forecasts an 80 percent chance of rain overnight into Friday morning, with up to three-quarters of an inch of new precipitation.

Meteorologist Brian Ciemnecki of the Upton office said showers until late Friday morning will be on again, off again, with the occasional isolated thunderstorm likely.

"You could get some that are heavy at times," Ciemnecki said.

As that cold front shifts winds back to the Northwest, conditions dry out and "colder-than-normal air is back for the weekend," Hoffman said.
