OMAHA, Nebraska — The Great Plains and Midwest are staring down a significant severe weather return on Thursday, April 23 — and the threat corridor is locked in. Damaging winds, very large hail, and tornadoes are all possible across a zone stretching from Oklahoma City through Wichita, Kansas City, Omaha, and up toward Sioux Falls as a powerful storm system charges into the region.
Thursday marks the end of a brief quiet stretch. The atmosphere is reloading fast — and residents from Oklahoma to South Dakota need to be ready.
Cities Directly in Thursday’s Storm Corridor
The Slight to Enhanced risk zone covers a dense population corridor:
- Nebraska: Omaha and Sioux Falls on the northern end — directly inside the yellow Slight Risk zone
- Kansas: Wichita sitting in the heart of the highest risk area Thursday
- Iowa: Des Moines on the eastern edge of the storm corridor
- Missouri: Kansas City in the crosshairs where cold front and dryline energy converge
- Oklahoma: Tulsa and Oklahoma City on the southern end of the active zone
- Minnesota: Minneapolis on the northern fringe of the broader marginal risk area
Primary Threats Thursday
Three distinct dangers are expected with Thursday’s storms:
- Very large hail — the atmosphere is loaded with enough instability to support hail-producing supercells capable of baseball-size or larger hail across Kansas and Nebraska
- Damaging winds — widespread wind damage potential as storms organize along the cold front pushing through the Plains Thursday afternoon and evening
- Tornadoes — isolated tornado potential exists, particularly where discrete supercells can fire ahead of the main line across Kansas, Nebraska, and Iowa
A Different Kind of Threat Than Last Week
Omaha, Nebraska and the surrounding Plains corridor have already been battered this spring — but Thursday’s setup has a distinctly different character than the recent outbreak events. Where last week’s major events featured 45–60% tornado probability with hatched Enhanced Risk zones, Thursday’s threat is more focused on very large hail and damaging straight-line winds as the dominant hazards, with tornadoes as a secondary concern.
That distinction matters for how people prepare. A wind and hail-dominant event means the danger is widespread across the entire storm corridor rather than concentrated in specific tornado tracks. Every community inside the yellow Slight Risk zone from Wichita to Omaha faces a meaningful chance of seeing damaging weather Thursday — not just those directly under a tornado warning…
