An absolutely bitter arctic air mass entrenched itself across the Midwest a couple of days prior to the New Year and continued to start 2018.  Air temperatures well into the negative teens to mid 20s were seen across Iowa throughout the event.  Fortunately, with the broad arctic high over the area, winds were not extreme, but were enough to drop wind chills well into the negative 30s and even negative 40s at times.  Suffice it to say, it was a prolonged stretch of dangerously cold air temperatures and wind chills.
