Preliminary Climate Summary for January of 2026: As mentioned last week, the temperature pattern in January was distinctly warmer than normal for the first half of the month, and colder than normal for the second half of the month. Most climate stations in Minnesota reported a mean monthly temperature that was 2°F to 5°F colder than normal. Extremes ranged from 53°F at Canby (Yellow Medicine County) and Marshall (Lyon County) on the 13th to -43°F at Brimson and Kabetogama (St Louis County) on the 24th. Minnesota reported the coldest temperature in the 48 contiguous states 9 times during the month. Most areas of the state reported a slightly above normal number of nights with subzero temperatures. For example, MSP recorded 12 such nights (the 50 yr average is 10), while International Falls recorded 21 such nights (the 50 yr average is 19). Despite the cold second half of January, only a modest number of daily low minimum temperature records were set (perhaps 25) within the state climate...
A warm, then bitter cold January: It appears that January weather this year will be divided into a warm half and a cold half. The first half of the month (January 1-16) saw temperatures around the state average between 7°F and 11°F above normal, with many areas reporting some daytime highs in the 40s F and a few places reporting at least one daytime high temperature of 50°F or higher. Now the second half of January (January 17-31) will be quite the opposite, with temperatures likely averaging 9°F to 14°F below normal. In fact, some areas may see close to record cold temperatures and certainly dangerous Wind Chill conditions. Some communities may record the coldest January daytime maximum temperatures since the winter of 2019. BTW, Minnesota has reported the coldest temperature in the 48 contiguous states 5 times so far this month, most recently earlier this week on January 20th when it was -30°F at Indus (Koochiching County) a few miles west of International Falls. There will likely be...
