Record November Warmth

Minnesota's dramatic and highly varying fall continues, with some of the warmest November conditions ever recorded in the state.

After a historically winter-like late October, the jet stream retreated into Canada by November 2nd, opening the door to a rush of historically warm air that overspread the entire region, lasting into Monday the 9th in southern and eastern parts of the state.

On November 3rd, with cloudless skies and light winds, temperatures soared into the 70s right up to the Canadian border, and along the shore of Lake Superior, reaching the 80-degree mark in parts of western and southwestern Minnesota. This marked the beginning of the warmest six-day period in any November on record throughout the state.

The warmth set a slew of records across the state. Duluth, International Falls, Rochester, St. Cloud, and the Twin Cities, all broke (and in some cases shattered) their records for number of November days with 70-degree (or higher) daily maximum temperatures. Of those,  Duluth, International Falls and St. Cloud all set new all-time high temperature records for November. One of Minnesota's longest-running cooperative observers, at Milan in Chippewa County, set its all-time November high temperature record (82 degrees F), and recorded three separate high temperatures of 80 degrees or higher.

The one record that did not fall is the state's all time high temperature mark for November. The highest known temperature recorded by an official observer anywhere in Minnesota during November remains at 84 degrees F in Winona on November 1, 1950.
