Long Island Forecast: Frigid temps continue through Wednesday, then a slow warm-up

Wednesday will feel like deja vu as an arctic air mass will continue to depress day and nighttime temperatures across Long Island, the National Weather Service forecasts.

Like Tuesday, Wednesday's high temperatures will linger in the low 20s, said James Tomasini, a meteorologist with the weather service’s Upton office.

"With wind chills, temperatures will be in the single digits," he added. "You combine that with a little bit of wind picking up late in the night, that will bring the wind chill down below 0."

Long Islanders should "bundle up," said meteorologist Bill Goodman with the weather service’s Upton office, as having skin exposed in this weather for an extended period can lead to frostbite "pretty quickly."

"Throw extra layers on, maybe double up on the socks, all that kind of good stuff," he said.

In Nassau County, warming centers at the Cantiague Park administration office, 480 W. John St. in Hicksville, and the Wantagh Administration Building, 1 King Rd., are open to residents from 9 a.m. to 4 p.m. Wednesday. The Mitchel Field administration building, 1 Charles Lindbergh Blvd. in Uniondale, will also be open as a warming center 24 hours a day.

A complete list of warming centers in Suffolk County is available through the Fire, Rescue and Emergency Services website. Facilities open Wednesday include the Riverhead Senior Center, 60 Shade Tree Lane in Riverhead, from 8 a.m. to 4 p.m., and the Southold Town Community Center, 1170 Peconic Lane in Peconic, from 7:30 a.m. to 4 p.m.

The Flanagan Senior Center, 423 Park Ave. in Huntington, will welcome those seeking warmth from 10 a.m. to 4 p.m. daily through Friday. The senior center on Shelter Island, 44 South Ferry Rd., will open as a warming center from 8 a.m. to 4 p.m. through Friday.

Long Island is expected to warm up to the 30s Thursday through Saturday and near 40 on Sunday, Tomasini said.
