It will be a great pre-Labor Day weather-wise Sunday with lots of sun and high temperatures in the low 80s for much of Long Island, and reaching nearly 85 on the North Shore.

And the only damper on the weather for the week ahead comes in the form of increasing humidity each day and a chance of showers that begins on Thursday.

"It'll be a Labor of lovely, Bruce Avery, a meteorologist for News 12 Long Island, said of Sunday and Monday. "It'll be summerlike this week -- a little bit muggy, then Thursday and Friday there'll be much-needed rainfall."

Labor Day starts the week off in the mid-80s with sunny skies continuing and lows in the upper 60s at night.

"It'll be somewhat humid on Monday," said John Cristantello, a meteorologist with the National Weather Service in Upton.

Temperatures get warmer on Tuesday when they reach into the upper 80s and it will be mostly sunny with nighttime lows in the low 70s.

High temperatures on Wednesday remain in the upper 80s when it will again be mostly sunny. "It will be more humid and will start feeling more and more uncomfortable," Cristantello said. Look for lows at night in the lower 70s.

On Thursday, highs in the mid-80s return when clouds come in and there will be a 20 to 30 percent chance of pop-up showers and thunderstorms. Evening lows will be in the upper 60s.

Friday starts the weekend with temperatures dipping to near 80 for highs and the chance of those pop-up showers and thunderstorms increasing to 40 percent. Nighttime lows will be in the 70s.

Avery said that looking ahead to Saturday there is even expected to be a "touch of fall" in the air.

"It'll be crisp with high temperatures in the upper 70s."
