Rain is likely on its way for Tuesday, a possible quarter to a third of an inch, forecasters say.

It's not enough, though, to whittle down by much the area's 4.32-inch precipitation deficit since April 1, but "every little bit helps," said Joe Pollina, National Weather Service meteorologist based in Upton.

The best chance for light but fairly widespread rain is after 3 a.m. through around noon on Tuesday, he said, with likely scattered showers tapering off by nighttime. Isolated thunderstorms are also a possibility.

Patchy fog can be expected after midnight, he said.

Long Island has been deemed "abnormally dry" by the U.S. Drought Monitor. April saw a 2.68-inch deficit, with May, as of Sunday, down by 1.64 inches.

Still, Saturday saw .26 of an inch of rain at Long Island MacArthur Airport, followed by .02 on Sunday.

Though not much, that rain, along with Tuesday's, "will definitely help improve things," Pollina said.

There's a 70 percent chance for rain Tuesday morning, the weather service said.

News 12 Long Island meteorologist Rich Hoffman said there will be "a little bit of wet weather the next 24 hours, but it will not put a dent in our abnormally dry conditions."

A fast-moving warm front enters the forecast Tuesday and is replaced Tuesday night by a cold front and more high pressure, which lingers through the weekend.

Hoffman said the result is a run of dry, sunny conditions.

"As of now, Wednesday through Sunday looks dry and sunny," he said.

Clearing begins Wednesday morning, with daily highs climbing again into the low 70s.
