What was the coldest wind chill temperature ever recorded in Minnesota? The answer can be tricky because the National Weather Service began to use a modernized wind chill formula in November 2001. Perhaps the coldest wind chill the Twin Cities has ever seen was -63 with the new formula (-77 with the old formula) back on January 22nd 1936. The temperature was -34 with a wind speed of 15 mph. Without a lengthy state-wide wind record, it is difficult to say when was the coldest statewide wind chill. There are some candidate dates though besides January 22, 1936. On January 9th and 10th, 1982 temperatures of -30 and winds of around 40 mph were reported in Northern Minnesota. This would translate to -71 by the new formula (-100F by the old formula.)
What about the highest heat index ever reached in the Twin Cities or Minnesota? The heat index is a "feels like" measure which factors together temperature and dew point. The highest heat index value ever recorded in the Twin Cities is believed to be 119 degrees, occurring on July 11, 1966 (our thanks to climate historian Charles Fisk). For Minnesota, an air temperature of 97 degrees teamed with an 84 degree dew point to create a heat index value of 127 degrees at the Red Wing airport at 3:00 pm on July 30, 1999.
* The maximum high temperature record for Minnesota was amended by the National Climatic Data Center. The record, previously cited as 114.5 degrees F at Beardsley, was rounded to 115 degrees.
