Temperatures hit 90 degrees again today in western Minnesota — in the last week of September.

Madison hit 91 degrees. I also saw 90 at Hallock, Roseau, Thief River Falls, Wheaton and Ortonville. That’s more than 20 degrees warmer than average for western Minnesota on Sept. 28.

The Twin Cities tipped out at 81 degrees. That’s average — for June 23.

Wednesday brings another day that will feel more July than almost October. Highs in the 80s will be widespread across Minnesota Wednesday afternoon.
