While we are on track for a relatively mild day, look for another blast of arctic cold starting tonight. Temperatures will fall and remain bitterly cold through mid week, with sub zero readings at night. Wind chill readings will dip into the dangerous zone at times as well. Some moderation in temperatures is expected going into the weekend.

On both Wednesday and Thursday nights, wind chills will range from 20 to 35 below. This can cause frostbite in less than 30 minutes. Bundle up in layers and limit your exposure to the cold.
