March 31 Record High Temperatures

Warm southwest wind helped boost temperatures to unseasonably warm levels around western Wyoming on Saturday, March 31.  In fact, several locations broke high temperature records for the date and set or tied all-time March temperature records.  High temperatures will be cooler on Sunday, April 1 as a cold front trudges east across the state during the day.
