0645 PM CST Wed Feb 25 2026
Valid 260100Z - 261200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected tonight.
...01z Update...
Midlevel short-wave trough is digging southeast across the central
Plains early this evening. 500mb speed max is forecast to translate
across KS into western TN by sunrise, and this feature may aid a
weak frontal wave and weak low-level warm advection along/north of
the synoptic boundary. Forecast soundings continue to depict weak
MUCAPE, but likely adequate for lightning discharge within stronger
elevated convection. Risk of severe is negligible the rest of
tonight.
