Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1135 PM CST Tue Feb 24 2026
Valid 251200Z - 261200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible across parts of the central
Plains, middle Mississippi Valley, and lower Ohio and Tennessee
Valleys.
...Discussion...
Within a belt of enhanced northwesterly flow aloft, a low-amplitude
midlevel impulse will advance southeastward from the northern Plains
to the middle MS Valley through the period. Despite limited
boundary-layer moisture through this corridor, steepening lapse
rates and focused ascent accompanying the impulse will support
southeastward-spreading convection with isolated lightning potential
across the central Plains toward the middle MS Valley during the
afternoon and evening/overnight hours. Enhanced low-level flow
within a well-mixed boundary layer may promote locally strong gusts
with initial convection over the central High Plains, though weak
buoyancy should limit severe potential. Farther east, isolated
thunderstorms are also possible within a developing warm-advection
wing over the lower OH and TN Valleys late in the period.
