Monday works out to be another sunny summer day for Long Island.

The National Weather Service's Upton office calls for daily highs in the mid to upper 80s across Nassau and Suffolk counties, with winds from the south at 7 to 14 mph.

There's a slight chance of rain, starting from late afternoon and extending into the overnight hours, but most of the day is expected to be dry and cloud free.

News 12 meteorologist Rich Hoffman said the best chance for showers or thunderstorms is overnight into Tuesday morning.

"I don't see many hours of prolonged wet weather," Hoffman said of daytime conditions Monday.

Monday night some clouds roll in, courtesy of a slow-moving cold front just east of Long Island. Overnight lows are in the mid 70s.

Showers remain a possibility for Tuesday, starting just after noon and as late as 11 p.m.

Chance of rain late Monday through Tuesday is 30 to 40 percent, the service said.

But, mostly on Tuesday, it's a day of sunshine, mixed with some clouds, and mid 80-degree temperatures, Hoffman said.

Wednesday is a complete return to blue skies and sunshine, as the cold front lowers temperatures slightly; daily highs in the low 80s are expected.
