Storminess Continues:
Strong thunderstorms moved over portions of northern and central Minnesota during the past week, especially on July 11-12 (Mon-Tue). Rainfall totals from 5-7 inches occurred over portions of 10 central Minnesota counties, causing widespread flash flooding. Tornadoes caused some damage to homes, businesses, and farms in Meeker and Stearns Counties. Large hail was reported in 4 Minnesota Counties, the largest, 2.5 inch diameter near Mora.
According to the Minnesota State Climatology Office the storm on July 11-12 was the largest mega-rain event since the Duluth flood of June 19-20, 2012. A mega-rain event is classified as a six-inch rainfall that covers at least a 1000 square miles, with a central core value of at least 8 inches. There have been only 13 such storms documented in Minnesota history, but 6 of these have occurred since 2002. You can read more about this weeks storms at the MN State Climatology Office.
