Recent Freezing Reports

20 May 2014 05:37 AM
Late last week and into the weekend experienced some very cold temperatures for mid May with the featured map display reports of sub freezing temperatures. The red crosses are reports below 29 degrees Fahrenheit and the blue squares are reports between 29 and 32 degrees. Temperatures can vary dramatically even with modest terrain differences, so many low laying areas in Iowa probably had frost on them at some point. Warmer weather this week and warm over night temperatures will help warm the soils back up and help crop development.

Good: 15

Cold May Day

16 May 2014 05:37 AM
Thursday was a very cold day in Iowa for May with highs struggling to reach 50 degrees and some locations reporting frozen precipitation. The featured chart looks at the hourly temperature reports from the Des Moines Airport versus long term hourly climatology for the middle of May. The bottom chart shows the hourly temperature percentiles with lower numbers indicating more extreme cold. Needless to say, we should be at much warmer levels than those on Thursday. Friday is starting off very cold as well with frost expected over much of the state this morning.

Good: 38
Bad: 10
Abstain: 7
