The city issued a snow alert for Monday evening — despite temperatures forecast to stay above freezing.

The Sanitation Department’s warning begins at 8 p.m. as wet weather could turn into sleet briefly during the tail end of the evening commute.

“We’re just being ready because we’re anticipating some slush in the morning,” said Kathy Dawkins, a DSNY spokeswoman. “We just want to be ahead of the game. With weather, you never know.”

About 650 sanitation workers were mobilized Monday to prep plows and get salt trucks ready in case the streets get slick.

“It’s a smart call,” insisted Harry Nespoli, head of the sanitation union. “We’re ready for whatever comes.”

But the call to action may be overkill, as meteorologists are predicting that the wintry mix of snow, sleet and ice will skip New York — instead causing a mess in New Jersey and north of the city limits.

Some sleet could come down Monday evening — quickly shifting to rain that will last through Tuesday morning, according to Accuweather meteorologists.

“Most of the time, it’s going to be plain old rain,” said Kerry Schwindenhammer, a senior meteorologist for Accuweather.

Temperatures will bounce back up to 50 Tuesday and stay mild through New Year’s Eve, when the mercury will hover around 53 degrees during the day.

By midnight, it will drop to 43 degrees, well above average for this time of year.

“You’re going to need a jacket, but it’ll definitely be one of the better New Year’s Eves as far as temperatures go,” Schwindenhammer said.
