Long Island weather: Rain overnight before a hot Friday

Showers are likely overnight and possibly into Friday morning before what it expected to be an unusually hot afternoon in the high 80s, the National Weather Service said Thursday.

A dry patch then starts this weekend, with no rain predicted until Tuesday night, the weather service said.

Friday, thermometers could reach 88 as a swath of warm air between cold and warm fronts settles in, the forecasters said.

Then daytime temperatures over the next seven days will cool to around the mid-70s, before popping back up to nearly 80 degrees by Tuesday.

Nighttime lows will run around the low 60s, the weather service added.

Friday’s chances for rain are 30%, though the clouds should slowly lift, allowing the sun, coupled with a westerly wind, to raise temperatures to just under 90 degrees — "well above normal," the weather service said.

However, the humidity will decline during the day, easing the impact of those higher temperatures. 

“A very comfortable night is anticipated with lows mainly in the middle 50s to middle 60s,” the weather service said. 

Saturday’s temperatures will then be as much as 10 to 15 degrees below normal, with the high officially forecast at 69 degrees.

Saturday through Tuesday should be at least partly sunny, as a cloud-clearing high pressure system settles into the west of the New York metro area. 

And then the odds of showers returning are estimated at 30% on Tuesday night and Wednesday.
