Long Islanders might want to hang up their sweaters -- at least for Wednesday -- as temperatures for the day are expected to be 10 degrees above normal, with parts of Nassau possibly flirting with 90, according to the National Weather Service.
There's "high confidence" for "a hot and humid day," the service said.
Much of the Island can expect temperatures in the upper 80s, feeling more like lower 90s in some cases, thanks to humidity, said Tim Morrin, weather service meteorologist based in Upton.
Records could certainly be approached, he said, as the record high temperature for the day at Long Island MacArthur Airport, in Ronkonkoma, is 88, set in 1989.
Still, it's expected to be "a brief warm spell," he said, with temperatures forecast to dip back to the lower 80s on Thursday.
As for early Tuesday, scattered showers touched parts of Long Island, mostly on the North Shore, during the morning commute.
The National Weather Service said a fast-moving, eastbound system crossed southern Connecticut and dropped rain on northern Suffolk County, starting just after 6 a.m. Precipitation amounts were less than one-tenth of an inch in most spots, Morrin said.
He said the heavier rain fell across the Twin Forks just before 7 a.m.
Morrin said it was doubtful a system expected to deliver heavy thunderstorms in several upstate counties would make its way toward Long Island later Tuesday.
"There's no reason to believe there's any more rain activity, at least through the lunchtime hours," Morrin said.
There also were showers reported on the South Shore, including parts of Freeport, but Morrin said early precipitation amounts there also appeared to be light.
Most of the rain for Long Island was likely to move into the Atlantic by 9 a.m., the service said.
