August recap

Dr. Mark Seeley of the University of Minnesota summarized our statewide August weather in his WeatherTalk blog:

Mean August temperature values from around the state were generally 2 to 4 degrees F cooler than normal. Only the second cooler than normal month in 2017 (May was the other). Extreme temperatures for the month ranged from 93 degrees F at Granite Falls (Yellow Medicine County) on August 1st, and just 30 degrees F at Embarrass, Brimson, and Crane Lake on the 25th. Some observers in St Louis, Lake, Cook, and Koochiching Counties reported frosts during the month. Minnesota did not report the nation's lowest on any date this month.

The most noteworthy climate attribute of August was the rainfall. Overall the statewide average rainfall was over 5 inches, ranking as the 11th wettest month of August in state history. Some western and southern communities reported their wettest August in history with total rainfall values over 10 inches. Redwood Falls topped the state network reports with over 13 inches. They reported the largest ever 1-day rainfall on August 17th in state history with a measurement of 8.12 inches. In addition over 40 climate stations in the state reported at least one new daily rainfall record during the month.
