Multiple rounds of severe thunderstorms impacted the region on May 26th producing widespread damage, leaving over 100,000 customers without power at its peak. The first wave was a bowing line that progressed east across southeast Missouri into western Kentucky and far southern Illinois between 5 and 10 AM. This was quickly followed by a second line that was mostly sub-severe which then exited our region by 1 PM. The environment was able to recover during the afternoon, providing ample fuel for another round of severe thunderstorms during the evening. Supercells formed across parts of the region between 6 and 9 PM. Meanwhile a line of storms developed to our west and moved quickly east-southeast across the entire area after 7 PM. This line sagged south toward the Kentucky/Tennessee border by 11 PM. Widespread damaging winds of 60 to 70 mph occurred with both rounds, along with large hail up to tennis ball sized, and numerous tornadoes. There have been 18 confirmed tornadoes from this event, including 3 EF-3's.
