Long Islanders should brace for very cold temperatures Wednesdayand subzero windchills Wednesday night, forecasters say.

Winds could reach 40 mph Wednesday night, contributing to wind chills of minus-10 to minus-15 degrees, said John Cristantello, a National Weather Service meteorologist in Upton. The wind chill advisory begins at 7 p.m. Wednesday and lasts until 8 a.m. Thursday.

Long Island escaped on Tuesday with just a dusting of snow and might get lucky again Wednesday as the forecast calls for scattered snow showers, according to the weather service.

"It's probably not going to be something that's widespread or would last very long," said John Cristantello, a weather service meteorologist in Upton.

Even if the wind abates, Thursday's temperature will struggle to get past 20.

Temperatures will linger about 10 degrees below normal until around Friday, when they should rise into the 30s, aided by the sun.

It's far too early in the month to say whether January will set records.

The state Department of Transportation and Nassau and Suffolk police said the evening commute appeared fairly normal.

"It is slow going ... People seem to be driving cautiously, as they should in this kind of weather, to get home safely," said Eileen Peters, a spokeswoman for the Department of Transportation.

The day began with multiple accidents on the Island's highways, including the Northern, Meadowbrook and Sagtikos parkways and the Long Island Expressway.

The snow also caused daytime delays on some arrivals and departures at LaGuardia Airport, according to the Federal Aviation Administration. With Gary Dymski
