Our severe weather season went off with a bang on Memorial Day with several tornadoes reported across the region. Along with tornadoes, we also saw heavy rainfall with portions of southeast Minnesota picking up 2 to 5 inches of rain by Monday evening.
Storm Survey results from the National Weather Service revealed at least 7 tornadoes Memorial Day afternoon across parts of Floyd and Howard Counties in Iowa and Fillmore County in Minnesota. While pictures and videos of these tornadoes revealed large, wedge shapes tornadoes, the actual tornadoes did not seem to be as strong as they looked.
The Charles City Tornado was rated as an EF-1 with estimated peak wind speeds of 110mph. The tornado that moved from Saratoga to near Lime Springs was also rated as an EF-1 tornado with estimated peak wind speeds of 105 mph and was on the ground for 9 miles. 4 EF-0 tornadoes touched down in Fillmore county including 1 near Greenleafton and 3 tornadoes that touched down just east of Hwy 63 between Chester, Iowa and Spring Valley. All of these tornadoes had peak winds of 85 mph or lower. There was also an EF-0 tornado just north of Glenville.
