Preliminary Climate Summary for December of 2024: With the expected warmer than normal last week of the month (to conclude next Tuesday), most climate stations in Minnesota will report a mean monthly temperature that is 3°F to 5°F above normal for December.

Minnesota reported the coldest temperature in the nation four times during December, on the 12th, 13th, 19th, and 21st. Moisture was generally above normal during December in most places. Statewide precipitation average was close to 1 inche, well above normal. Many areas of the state reported from 1 to 2 inches of precipitation (liquid equivalent) and some areas along the north shore of Lake Superior reported over 2 inch...
