Strong to severe thunderstorms developed across northeastern South Dakota during the afternoon of Sunday the 17th and as the storms moved into extreme western Minnesota they produced a tornado outside Wheaton along with widespread wind damage to trees and power lines. As they continued their march eastward the storms congealed into a Mesoscale Convective System (MCS) that continued to produce large hail and strong wind gusts into the early hours of Monday morning. The strongest wind gusts reported were 76 mph from Appleton along with a report from a storm chaser of 77 mph near Cosmos in Meeker County. Hail two inches and larger was reported in Le Sueur and Rice counties. Heavy rain was also an issue with these storms as amounts three inches and above fell in a swath from Kandiyohi to Goodhue counties. Some of these locations, such as Cannon Falls, once again experienced flash flooding just days after receiving substantial rains and flooding on the 14th.
