A winter mix of precipitation is expected Friday night into Saturday. Then, an extended period of sub-freezing temperatures is expected through Monday midday.

Quiet weather remains in place as you are heading out the door on this Friday morning, but there are a few areas of patchy fog to start.

Get your driveway ready: Grab some salt, sand, or even kitty litter now. You’ll want it on hand for icy walkways and driveways. Check on people you care about: Call your neighbors, elderly relatives, and friends. Make sure they’re prepared for the cold. That below-zero cold can be dangerous.

If temperatures do come up into positive territory on Friday afternoon, don’t expect it to be by much. Winds will be northwesterly around 10 to 20 miles per hour, with gusts near 30 miles per hour, keeping wind chills in the -10 to -20 range after the morning.

A major winter storm stretching from Texas to New England could affect more than 150 million Americans this weekend.

Dangerous cold, ice and possible snow move in Friday night. Wind chills could drop below zero — now is the time to prepare and stay off the roads.
