Long Island weather: Rainy and windy

After a mild and sunny Friday, Long Island will see rain and high winds as the weekend starts Saturday.

The National Weather Service on Friday evening said it will rain Saturday, mainly after 10 a.m., with a chance of precipitation pegged at 100%.

The high temperature Saturday is predicted to be a relatively balmy 59 degrees — the normal high for the date in Islip is only 48 degrees — and a south wind is expected to blow at 17 to 25 mph with gusts as high as 41 mph.

Saturday night will be mostly cloudy, then gradually clear, with a low temperature of around 32 degrees, according to forecasters.

Sunday and Monday, meanwhile, should be sunny, with highs in the mid- to upper 40s.

"High pressure builds over the Atlantic ... [on Friday night], allowing a cold frontal passage to occur late Saturday. High pressure builds in Sunday into Sunday night and gradually slides offshore Monday into Monday night," according to the area forecast.

More rain is possible Tuesday and Wednesday, when highs both days are expected to be about 57 degrees.

And then the sunshine will return Thursday with a high temperature of around 50 degrees, the weather service said.
