NWS Storm Prediction Center Norman OK
0749 AM CDT Sun Aug 31 2025
Valid 311300Z - 011200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Overall severe weather potential is expected to be low today and
tonight.
...Discussion...
Modest-strength mid-level northwesterly winds aloft will persist
over the Great Plains, to the east of the Rockies-centered upper
ridge and an upper low off the coastal Pacific Northwest. Weak
convergence/subtle surface troughing will be prevalent in
association with a persistently moist air mass across the southern
Plains. Although a few strong storms could occur across parts of
Kansas/Oklahoma into Texas this afternoon into evening, the
combination of only modest instability and relatively weak
deep-layer shear should limit the overall severe-weather potential.
A few strong storms could also develop across southwest New Mexico
and southeast Arizona later this afternoon into this evening, with
some stronger wind gusts a possibility.
