Overview
Two rounds of severe thunderstorms impacted the region on May 20th. The first occurred during the overnight hours between midnight and 5 AM. Then we had a lull during the late morning into midday before additional clusters of storms formed by 2 PM across southeast Missouri and pushed east into west Kentucky through the early evening. There were two tornadoes that happened with the first round, including an EF-1 that struck the north side of Cape Girardeau, MO shortly after 1 AM. There were scattered reports of wind damage and some hail with these storms, although most of the hail was sub-severe (dime sized or smaller). |
