An unusually hot and muggy air mass for June brought triple-digit temperatures to much of southern, central, and western Minnesota on June 20, 2022.
The heat had actually begun one day earlier, on Fathers' Day (June 19), with temperatures soaring through the 90s across much of the state, with some 100-degree readings in western Minnesota, including 102 F at Sabin and Crookston, 101 F at Georgetown, and 100 F recorded from Benson down to Redwood Falls.
With temperatures staying in the mid-to-upper 70s overnight, dew point temperatures climbing to near 70 F, and winds increasing from the southwest ahead of a cold front, the stage was set for even more widespread heating on Monday.
Temperatures crossed the century mark across the Twin Cities area, and in much of central and western Minnesota. The high temperature of 101 F at the Twin Cities airport set a record for June 20th, and was just the tenth 100-degree reading on record during June, and the first since 2011.
The heat was broken in northwestern Minnesota by damaging thunderstorms, but otherwise covered the entire state, including much of the Lake Superior shore, where the southwesterly winds prevented a refreshing lake breeze in many areas.
This was the warmest June 20th on record at many stations new and old, and record high temperatures set on Monday at other 1st-order climate stations included 101 F at St. Cloud and 94 F at Duluth.
