A blast of arctic air will be making its way through Iowa this week.
Overnight temperatures are expected to fall below zero every day this week in the Storm Lake area. It will get especially chilly later in the week, as the National Weather Service has issued a Wind Chill Watch for the area from Thursday into Saturday, as high temperatures during those days should be sub-zero. During that extremely cold period, wind chills are expected to fall to 20 or 40 degrees below zero or colder. The National Weather Service urges those with holiday travel interests from late Wednesday through the end of the week to pay close attention to forecast updates, and be prepared to consider alternate plans.
Before the temperature takes a tumble, more snow is anticipated, with a bit of snow and freezing rain possible later today (Mon) and tonight. Then starting Wednesday afternoon into Thursday morning, around three inches of snow is predicted in the Storm Lake area. Be prepared for areas of blowing snow toward the end of the work week.
