September blew in on decidedly summery notes. Temperatures Thursday afternoon soared into the 90s across most of western Minnesota. I also saw 90 degrees in Blaine in the northern Twin Cities and in Princeton farther north.

You can see on the temperature map above that Minnesota is riding the eastern end of a toasty air mass that covers the entire western half of the nation. It’s well over 100 degrees in parts of west. 

Friday brings another steamy September day to southern Minnesota, but a cold front cutting southward will slide across the Twin Cities between about 1 p.m. and 3 p.m. Friday. Highs will be noticeably cooler across northern Minnesota Friday, but temperatures near 90 degrees are again likely from the Twin Cities southward. 

A few short-range mesoscale forecast models develop storms along the frontal zone late Friday afternoon. The most likely region to see scattered strong storms favors southeastern Minnesota, western Wisconsin, and northern Iowa.

Here’s the National Oceanic and Atmospheric Administration’s NAM 3 km model between 4 p.m. Friday and midnight Saturday.

A cooler, more comfortable air mass rides into Minnesota behind Friday’s cool front. Highs will be in comfy 70s across most of Minnesota Saturday and Sunday, with a few 60s up north. 

Warmer than average temperatures and mostly dry weather conditions look likely for the first 10 days of September. 

Highs return to the 80s for most of Minnesota next week. A few locations could hit 90 degrees once again. 

September still looks likely to see above-average temperatures overall. NOAA’s monthly temperature outlook for September favors warmer-than-average conditions over much of the United States.
