This Labor Day may be the first day of meteorological fall, but summer's heat and humidity blanketed Long Island, according to the National Weather Service.

Monday turned out to be warm and humid, with a chance of scattered afternoon showers and thunderstorms, said David Stark, meteorologist with the service's Upton bureau.

The high hit 85 in Islip just before 4 p.m., but with the moisture in the air, it felt more like 91 degrees in some parts of the Island, such as Shirley, meteorologists said.

After sunset, the chance of rain goes down but the mugginess remained, Stark said. Lows on Monday will be in the upper 60s to low 70s.

Monday also marks the start of meteorological fall, a three-month period that is based on the annual temperature cycle, according to the National Oceanic and Atmospheric Administration's National Climatic Data Center.

But if you're starting to miss summer, don't worry: Astronomical fall, which is based on the Earth's position relative to the sun, begins Sept. 22 -- a full three weeks away.

Highs on Tuesday will be in the low 80s on the East End and the mid- to upper 80s for the rest of Long Island, Stark said.

The humidity will continue, making it feel closer to 90 degrees, Stark said.

A chance of showers and thunderstorms returns Tuesday after 8 p.m. Lows on Tuesday again will be in the upper 60s to low 70s.

The first relief from the humidity will come Wednesday, which is expected to be a dry day with highs reaching into the low to mid-80s.

The respite will come with a front moving through the region Tuesday night into Wednesday morning, Stark said.

"That's going to bring humidity levels down" to a more comfortable level, he said.

There is no chance of precipitation Wednesday, he said. Lows will be in the low to mid-60s.

Thursday will continue to have lower humidity, with highs in the low 80s and lows in the low to mid-60s. Highs on Friday will be in the low 80s.

"It should be a better end to the week than what we're seeing here in the next few days," Stark said.
