Areas of fog that developed early Thursday over Long Island had burned off by midmorning, leaving mostly cloudy skies, a chance of rain and temperatures climbing into the high 70s, forecasters said.

“Tropical moisture from the remnants of Irma will move in today,” the National Weather Service said, bringing showers and “a few thunderstorms.”

The chance of rain Thursday is about 30 percent, with isolated showers in the afternoon, then scattered showers and thunderstorms after 4 p.m., the service said. Rain is again possible before 10 p.m., with isolated showers through early Friday.

Thursday’s “a bit humid,” said News 12 Long Island meteorologist Matt Hammer. Long Island will see mostly cloudy skies but with a “chance for a few breaks of sun” and “the risk for a passing shower or storm — especially later this afternoon and evening.”

Thursday night is “mild and muggy,” Hammer said.

Anyone venturing to the beach Thursday should know there’s a high risk of rip currents at eastern Long Island beaches through this evening, according to the weather service.

Lows overnight Thursday should dip to the mid-60s under cloudy skies, the service said.

Friday brings mostly cloudy weather with highs again near 80 degrees, the service said. The chance of precipitation is about 20 percent “before improving weather arrives for the weekend,” the service said. Temperatures will continue to be slightly above average into the weekend.

Beginning Friday, building ocean swells from Tropical Cyclone Jose “will pose an increasing threat for high surf, dune erosion, localized washovers and dangerous rip currents along the ocean beachfront” through early next week, the service said.
