Long Island forecast: Cooler, less humid weather to continue

Long Islanders will see more comfortable conditions this week, as heat and humidity will remain low until at least the weekend, according to the National Weather Service.

Monday's forecast includes mainly dry conditions with the potential of a passing thunderstorm or showers in the afternoon, said Joe Pollina, a National Weather Service meteorologist. The daily high will be in the low to mid 80s with the nighttime low around 65. 

The relief from several days of 90-plus temperatures came in the form of a cold front that produced thunderstorms across the area Saturday night and caused a shift in wind direction, the weather service said.

“The winds have been pretty much out of the south or southwest, which was ushering in warm and humid temperatures and conditions,” said weather service meteorologist Matthew Wunsch. “But behind the thunderstorm last night we have a northwest flow that's bringing in a drier and a cooler air mass.”

Dry conditions will remain until about the middle of the week with highs in the low to mid 80s into next weekend and evening lows in the mid 60s.

“It should be pretty moderate through the week,” Wunsch said.

There’s a 40% chance of showers after 8 p.m. Thursday, jumping to 50% Friday under otherwise partly sunny skies, according to the weather service’s five-day forecast.
