CENTRAL UNITED STATES — The Storm Prediction Center is flagging a potentially significant multi-day severe weather and tornado outbreak threat stretching from the central and southern Great Plains all the way into Dixie Alley between Thursday and Monday. Forecasters warn that five consecutive days of severe weather risk are on the table, with the tornado threat beginning across Kansas, Nebraska, and Iowa on Thursday before shifting southward and eventually expanding eastward into Dixie Alley by Monday.
The SPC Days 3 through 7 outlook map, generated on April 21, 2026, color codes each day’s threat zone separately, clearly illustrating how the severe weather risk is expected to evolve and track across a broad swath of the country over the course of the multiday event.
Thursday Through Saturday Threat Focused on the Great Plains
The initial severe weather threat on Thursday is centered across a corridor spanning Kansas, Nebraska, and Iowa, shown in cyan on the outlook map. Forecasters indicate the dry line across central Kansas and Nebraska will serve as the primary trigger for storm development on Thursday, with tornado potential accompanying the severe weather risk across that corridor.
By Friday, the threat shifts southward and consolidates across Oklahoma and surrounding areas of the southern Plains, shown in purple on the map. Saturday continues the severe weather pattern across a similar area shown in green, with Oklahoma remaining at the core of three consecutive days of tornado and severe weather risk across the southern Plains.
Sunday and Monday Threat Expands Into Dixie Alley
As the pattern progresses into the weekend and early next week, the severe weather focus begins expanding significantly eastward. Sunday’s threat zone, shown in red, indicates a continued risk across the southern Plains, while Monday’s threat zone shown in bright magenta expands dramatically into Dixie Alley, covering portions of Missouri, Arkansas, Tennessee, Mississippi, and Alabama…
