Winter Storm Has Sioux Falls in Its Sights Friday, Saturday

After Sioux Falls got seven plus inches of snow on Friday and Saturday, a serious bit of cold air will settle on the Upper Midwest this weekend. Those temperatures combined with strong wind will create dangerous wind chills. So, The National Weather Service has issued a Wind Chill Warning for most of South Dakota and parts of Nebraska, Iowa and Minnesota until noon Sunday.

A WIND CHILL WARNING MEANS THE COMBINATION OF VERY COLD AIR AND THE WIND WILL CREATE DANGEROUSLY LOW WIND CHILL VALUES. FROST BITE CAN OCCUR QUICKLY AND EVEN HYPOTHERMIA OR DEATH IF PRECAUTIONS ARE NOT TAKEN.

Sioux Falls is forecast to have a high of 0 early in the day with temperatures falling throughout the day. Low temperatures early Sunday morning will be around 28 below zero. Additionally the winds will cause blowing and drifting snow reducing visibility, especially in open areas.
