"Record-Breaking Arctic Blast to Bring Sub-Zero Temps and Blowing Snow Across US"
An arctic cold outbreak is set to bring potentially record-setting frigid air to much of the US, including the Deep South, with daily records for mid-January at risk of being broken from Montana to the Gulf Coast. The cold air will arrive in two rounds, with temperatures dropping below freezing for several days and potentially reaching lows in the minus 20s and even minus 40s in some areas. Strong winds will also produce dangerous wind chills, and the cold pattern is expected to linger into the week of January 22.
