All of these values are statewide areal averages computed by the IEM.

Day 5 of 6 below 60 degrees?

11 May 2010 05:13 AM

A model's forecast for today and tomorrow have yet to verify, but if it does, this period would tie a record for consecutive days below 60 in May.

A bit frosty for May

10 May 2010 05:10 AM
Clear skies and calm winds helped temperatures to drop to frosty levels Sunday morning as shown by the featured IEM analysis of low temperatures. The full impacts of this cold event will take a bit to be determined, but the corn crop was probably not far enough developed to be significantly impacted. Trees and flowers took the brunt of this cold weather with more cool weather expected this week. The big story will be the heavy rainfall along with highs only in the 50s for the next few days.
