The Arctic Express will continue its icy grip on the Hudson Valley on Wednesday, bringing wind chill readings below zero and biting, 25 mph gusts, forecasts predicted.

With temperatures hovering around 20 degrees, Wednesday could be the coldest day in the region since January 2011, which set records for snowfall, News12 meteorologist Joe Rao said.

Anyone who has to remain outdoors for an extended period should bundle up as a combination of wind and cold air settles in from Yonkers to Woodstock.

"You've got to cover all the extremities," said Brysen Van Eck, a News12 meteorologist. "If you work outdoors or wait for your train for a half hour, you could get frostbite."

From 5 to 8 a.m. Wednesday, the temperature in Yonkers is expected to sit at 14 degrees, with a 13 mph breeze, and Poughkeepsie is forecast to fall to 10 degrees at 7 a.m., with a wind of 10 mph.

"The jet stream has dipped into our area, and the jet steam is coming out of the Arctic," Van Eck said. "It's coming right down through the Northeast, bringing transpolar flow."

The bitter cold front howled through the United States from the Dakotas to the Northeast, bringing the coldest weather this winter, according to the National Weather Service.

The Hudson Valley's cold snap is expected to linger into Saturday, when the high is expected to reach 32 degrees.

Van Eck said snow might develop Friday.

A warming trend will not arrive until the middle of next week, Van Eck said, bringing temperatures in the 40s.

To avoid delays and inconvenience for those waiting for Metro-North trains, the Metropolitan Transportation Authority urged commuters to sign up for email and text message service updates. Service information also is available online at
