What happened

The episode as NWS OAX wrote it up.

A prolonged Arctic surge of cold air plunged south across western Iowa on January 2 and continued through midday January 4. North winds of 25 to 40 mph accompanied the surge of cold air and when combined with air temperatures which fell below zero, produced wind chill temperatures of 35 to 50 below zero much of the period. In addition to the extremely cold wind chills, a 24 to 48 hour snow event preceded and accompanied the Arctic surge dropping 2 to as much as 7 inches of new snow on much of the area. When combined with the strong winds, blowing and drifting of the freshly fallen snow occasionally reduced visibilities below 1/2 mile, mainly from the evening of 1/2/99 through late afternoon on 1/3/99. The drifting snow also closed some east to west roads, mainly in rural areas.
