Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1251 AM CDT Sat Sep 27 2025
Valid 271200Z - 281200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
A severe threat is not expected to develop across the continental
U.S. today and tonight.
...DISCUSSION...
At mid-levels, a trough will move through the southeastern U.S.
today, as a ridge remains over the central U.S. A low will remain
over southern California. At the surface, a moist airmass will be in
place ahead of the trough in the Southeast, and in parts of southern
Arizona. Scattered thunderstorms are expected to develop this
afternoon in these two areas, but the combination of instability,
lift and shear should be insufficient for severe storms. No severe
threat is expected across the remainder of the continental U.S.
today and tonight.
