I broke it

FSD reached 89 which was good not only for a daily record but the warmest March temp in history. I reached 93 IMBY. Felt like summer. Spent most of the day outside at a family BBQ. Quite enjoyable.

The 5 minute temps - may not be a 5 minute avg- which is what ASOS uses as official temp--

Bison on Highway 191 a couple miles north of town.

Automation at its finest. Most don't know that an official temp from Asos is a 5 minute avg. Not a big deal you say? So even though it reached 92F for two consecutive minutes , it doesn't count and the official high for DSM is 91F. 92F would have been the warmest March day ever, but 91F tie 3 /29/1986. Seen it do this for -20F also, but -19F it's official. Frustrating at times. Certainly not like the old days with a min/max thermometer in a instrument shelter. In that case- it would have been 92F.
