A storm that dropped on average about 3 to 5 inches of snow on Long Island moved out in time for the Friday evening commute — but bitter cold is on its heels, forecasters said.

An arctic front is expected to bring near-record cold temperatures overnight, according to the National Weather Service.

Watch for a “hard freeze” making for icy roads, News 12 Long Island meteorologist Rich Hoffman said.

Temperatures are expected to fall into the teens overnight, with winds gusting 30 to 35 mph that will make it feel like zero, forecasters said.

Earlier, as the snow fell, Nassau County Executive Edward Mangano said he was worried about travel conditions once the snow moved out and the sun went down.

“I would be more concerned about what happens tonight,” Mangano told News 12 Long Island in a telephone interview, when drivers may experience “potential black ice issues.”

The storm arrived later than expected Friday morning, enabling schools to stay open and putting more commuters on the roads than would be expected, officials said.

Only one public school district — Montauk — canceled classes because of the snow. Some districts canceled after-school activities.

Police officials in Suffolk and Nassau said they saw no uptick in traffic accidents during the morning commute.

National Weather Service meteorologist Carlie Buccola said the temperature on the roads was warmer, so the snow mostly accumulated on grassy surfaces. Temperatures hovered in the low 30s during the storm.

The storm turned out to be a record breaker — at least for March 10. The 4 inches recorded at Long Island MacArthur Airport broke the old daily record of 2 inches set in 1993, according to the weather service.
