This is a better summary for DLH starting with the beginning of the water year. Rollercoaster temps, and generally dry. Forgot about this section under the climate n past wx page.

May 2026 finished exactly 1.0F above the long term average in Minneapolis. 2.24” of precipitation which is -1.67” below average. There was a late freeze on May 6th.
 

The somewhat surprising 0.37” we received yesterday couldn’t have been timed better.

Spring finished tied w/ 1987 & 2000 for 8th warmest on record of 153 at Detroit. Naturally it was 100% due to March/April, as May finished cooler than avg. An about face from the 44th coldest winter.

How did you find the combined temperature average for Spring, and the ranking? I don't see any seasonal summary on the NWS local offices' climate web sites. All I can see is the climate summary for each month. Also, I can use the NOWDATA to see the average value or each (single) month. I am just curious.
