A storm brought an extended period of hazardous winter weather to southeast Minnesota ahead of the Christmas holiday. Periods of snow fell from December 21st into the 23rd. Most accumulations were in the 3 to 5 inch range but combined with winds of 35 to 50 mph, significant blowing and drifting resulted. It even resulted in some whiteout conditions. The wind also combined with an influx of arctic air to create dangerously cold wind chills from the 22nd into Christmas morning. Values of 25 to 45 below zero were common during this period with the lowest calculated wind chill of -47 at a mesonet site near Eyota (Olmsted County). Numerous schools closed in advance of the storm. Deliveries of fuel were delayed causing some gas stations to run out of fuel.
