The seemingly endless summer of ‘21 continues to set records. 

The first half of meteorological fall is the warmest on record for Duluth, Minn., and ties the warmest on record for the Twin Cities. Minnesota is just one of the areas setting records for the warmest start to meteorological autumn (September-November) on record.

And on the record early autumn warmth that covers most of the northern United States:

Minnesota is running about 10 degrees above average so far this October. 

So why are we feeling record warmth this fall across the Upper Midwest? It’s likely the  combination of well-established climate change trend of warmer fall seasons in the Upper Midwest and the La Niña event in the tropical Pacific Ocean.

Henson’s piece details the connections:

A cold front brings Minnesota back to reality later this week. But temperatures could push the 70-degree mark again by next Tuesday.
