Long Islanders will want to prepare for a wet Tuesday morning commute, as steady rain is expected to move in before daybreak, forecasters said.

Look, too, for windy conditions during the day and the potential for “a rumble of thunder or two,” said Jay Engle, National Weather Service meteorologist in Upton.

The fast-moving system could bring 1⁄2 to 3⁄4 of an inch of rain to the Island before the precipitation wraps up from west to east during the afternoon, he said.

Temperatures Tuesday were expected to warm up to the mid-50s, with 38 degrees the normal high for the day, said Rich Hoffman, News 12 Long Island meteorologist. There’s potential, he said, for the day’s record for high temperature — 55 degrees set in 1999 at Long Island MacArthur Airport — to be broken.

Then, along come “drier conditions and colder air” overnight Tuesday into Wednesday, “with temperatures returning to slightly below seasonable levels by Thursday,” the weather service said in its regional summary.

The rest of the workweek was looking to be sunny, with Wednesday expected to see a high of around 40 degrees, and Thursday and Friday rising to around the mid-30s.
