Friday is looking to be mostly sunny, with increasing chances for rainfall mostly in the overnight hours, forecasters said.
Chances increase after 8 p.m., but the most likely time for rain to move in is around 2 a.m. Saturday, moving from west to east, said Joe Pollina, weather service meteorologist based in Upton. Easternmost Long Island could still see some lingering showers into midmorning, he said.
Forecasters are calling for 1/3 of an inch to 1/2 inch of rain.
The rainfall, he said, would bring some relief, at least for a couple of days, from the fire weather conditions the area has seen the past two days. Relative humidity is "a bit higher today, but still very low," according the weather service's Facebook page. Still, "lighter winds will greatly reduce concerns for fire weather."
As for temperatures, Friday is looking at highs in the upper 50s to low 60s, he said.
Highs Saturday are expected to be in the lower 60s for most of the Island, possibly down to lower 50s for the Twin Forks, he said. There's also a 40 percent chance of more rain Saturday night before midnight, he said.
Apart from possible isolated showers, Sunday is expected to be dry, with highs around 60, slightly lower for the East End, he said.
