Long Island weather: Rain-snow mix moves in Tuesday night

Tuesday starts out with cloudy skies, giving way to some sunshine, as temperatures warm up to the mid-30s, forecasters say.

Then, another bout of precipitation enters the picture, as clouds “increase late Tuesday night into Wednesday as a storm system approaches from the Tennessee Valley,” the National Weather Service said in its regional summary.

Long Islanders can expect to see precipitation starting as snow Wednesday morning, possibly around the commute time, switching to rain as temperatures warm up, potentially by around noontime, said Jay Engle, a weather service meteorologist in Upton. Highs in the mid-40s were expected, as was less than an inch of accumulating snow, as of the late Monday afternoon forecast.

Rain, possibly ending as snow, can be expected to wrap up in the early morning hours of Thursday, Engle said.

Drier air then moves in, with Thursday looking at highs in the low to mid-30s.
