0747 PM CDT Thu Sep 04 2025

Valid 050100Z - 051200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not expected tonight.

...Southwest/south-central KS...
A sharpening cold front will sweep southward across KS tonight.
Mostly elevated convection should increase to the cool side of this
undercutting boundary, mainly during the early morning/pre-dawn
hours. Initially steep mid-level lapse rates and adequate MUCAPE
could support a few storms capable of producing small hail and
locally strong gusts amid strengthening low-level northerlies.
Overall severe potential still appears fairly low.
