Iowa had perhaps its coldest day so far this winter season on Thursday with high temperatures generally in the single digits and lows well below zero. The featured map presents IEM computed minimum wind chill temperatures from airport weather stations. Values below -30 can be found over portions of northern Iowa. Friday will start off in a similar manner to Thursday with dangerous wind chills and well below zero temperatures, but will be slightly warmer during the afternoon hours. The near term forecast continues to look cold with perhaps a warm up by the end of next week.
