Unique Storm of December 15, 2021:
"The storm system that crossed over Nebraska, Iowa, Minnesota, Wisconsin and Illinois over December 15-16 was almost totally unique in many of its atmospheric attributes. Hundreds of temperature and dew point records were set with the rapid transport of heat and moisture from the south. The wind structure of the atmospheric layers supported record-setting wind speeds, as well as producing 25 reports of tornadoes (12 in NE, 13 in IA), and three suspected reports of tornadoes in MN, yet to be verified. Though fast moving, the storm system produced some record-setting rainfall amounts as well. Among the most rare and unique measurements of the storm were: confirmed tornadoes on the ground near Lewiston (Winona County) and Hartland (Freeborn County), the first ever observed such storms in Minnesota during the month of December; a radiosonde (balloon) measured precipitable water measurement from the Twin Cities (integrated water vapor content in the atmosphere overhead) of 1.23inches, the highest measurement ever made in Minnesota during the months of December, January, and February; a dew point measurement at MSP airport of 55°F, the highest historical dew point measurement historical for the Twin Cities between December 6th and March 6th; a maximum temperature reading of 66°F at Caledonia, Winona, and Austin, all-time statewide record high for this time of year, and about 30-35 degrees F above normal."
