Right now: tornado watch has been issued in the radar-hole-land of west ND, east MT.
Tomorrow, I agree with you. The area from Kansas City to the MO/AR border should see several thunderstorms. I think there will be some severe wx in this area, and also some areas of elevated T-storms that are sub-severe.
NAM 84-hr rain totals show pretty high rain amounts, most of Missouri, to Memphis and Paducah.
