0800 PM CDT Wed Sep 23 2026

Valid 240100Z - 241200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
WESTERN DAKOTAS...

...SUMMARY...
Isolated severe thunderstorms are possible this evening across parts
of the western Dakotas.

...01z Update...
Primary severe potential will be relatively short term and focused
across the western Dakotas, with isolated severe hail and wind
remaining possible on an isolated basis this evening. These storms
are being influenced by a northeastward-transitioning shortwave
trough and related belt of moderately strong flow aloft. Sufficient
instability exists potentially for an additional severe storm or
two, but nocturnal boundary layer influences will become more
prevalent over time, with a diminishing intensity trend expected.
