Millions under prolonged flash flood threat as relentless storms pummel Midwest, Central Plains

A Level 1 out of 5 risk of severe thunderstorms covers more than 20 million people, stretching from Amarillo, Texas, to Toeledo, Ohio, with damaging wind gusts being the main hazard.

THE TAKEAWAY

  • A persistent pattern is set to bring heavy rain, flooding and severe storms to the Midwest and Middle Mississippi Valley into Saturday.
  • Rounds of thunderstorms and downpours developed from the Texas Panhandle, across the Midwest to the Great Lakes on Tuesday.
  • The heaviest rain is expected just north of Kansas City, across parts of Kansas and Missouri, where a Level 3 flash flood threat is in effect into Wednesday morning.

Relentless storms are slamming parts of the Midwest and Central Plains as a stalled weather pattern fuels a weeklong flash flood threat that will last into Saturday. 

A Level 2 out of 4 risk of flash flooding stretches across a corridor from Amarillo, Texas, across Missouri to northern Indiana.

This multiday threat of heavy rain and flash flooding is taking shape across the Midwest and Middle Mississippi Valley this week as a stubborn southern heat dome acts as an atmospheric block.

This high-pressure ridge is pulling a continuous plume of tropical moisture out of the Pacific and Mexico, steering it north through the Rockies before bending it east over the Plains and Midwest.

Simultaneously, Pacific Northwest atmospheric troughs are pushing south, driving a front that will stall directly across eastern Kansas, Nebraska, Iowa and Illinois.

Because the heat dome prevents this front from moving south, moisture-laden storm clusters will repeatedly track over the exact same corridor.

This sets up a prolonged, high-intensity rain threat through mid-to-late week across the Middle and Upper Mississippi Valley, where 5 to 8 inches of rain could trigger widespread flash flooding all week long.
