Residents of the Northeastern US are probably tired of being told to bundle up, but another winter storm is getting ready to sweep through this weekend, bringing the potential for some of the coldest weather the region has seen in the past 20 years.

The National Weather Service is warning of dangerous wind chills in the mid-Atlantic region through New England. The frigid conditions come ahead of another coastal storm, which the service predicts will bring heavy snow to New England this weekend.

Temperatures are expected to drop through the weekend and will likely hit their lowest by Sunday night or early Monday morning, warming back up again Monday and Tuesday.

At the lowest possible forecast, many cities in the Northeast, including Boston, Hartford, and maybe even New York City, could experience temperatures below freezing.
