Friday morning commuters can expect dangerously slippery conditions, forecasters say, with falling temperatures causing overnight rain and snowfall to freeze.

“There is a high threat for icy conditions to develop during the morning commute, resulting in hazardous driving conditions,” the National Weather Service said in a special statement issued late Thursday afternoon.

Along with accumulating snow, the “greatest concern” is for “flash freezing,” with temperatures heading down to the mid- to upper 20s, the weather service said.

That would particularly be the case for untreated roadways, sidewalks and parking lots, said Brian Ciemnecki, a weather service meteorologist in Upton.

Expect a messy morning rush hour, given the “threat for icy and snow-covered roads,” said Rich Hoffman, a News 12 Long Island meteorologist.

The Thursday afternoon forecast was for snow to wrap up by around 9 a.m. Friday, with 1 to 2 inches expected for Long Island.

While not likely, up to 3 inches couldn’t be ruled out, Ciemnecki said. That would be if “heavier snow bands develop or the rain changes over to snow an hour earlier than forecast,” the weather service said.

“Gusty northwest winds will bring colder, drier air for Friday and Friday night,” the weather service said in its regional summary.

Temperatures Friday were expected to rise to only 32 degrees or so, feeling colder thanks to wind chill, then nose-dive to about 11 degrees by daybreak Saturday and remain below freezing through the day, the weather service said.

Sunday and then Sunday night bring further chances for precipitation, looking to start out as snow for a few hours in the morning, switching to rain for the duration, the weather service said.
