Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0206 PM CDT Thu Sep 25 2025

Valid 271200Z - 281200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Scattered thunderstorms are expected across the Southwest/Four
Corners states, and from the Southeast to the Mid-Atlantic. Severe
storms are not forecast.

....Discussion...
Relatively weak winds aloft will exist over most of the CONUS, with
the main upper jet over Canada. Thunderstorm potential will still be
focused over the Southwest and Southeast, where slow-moving upper
lows will exist.

Given the persistence of both upper features, instability is
forecast to be weaker than on the previous day due to clouds and
overall moistening. For the southwestern states, slightly stronger
instability may develop over central/eastern AZ, with around 1000
J/kg MUCAPE possible. Modest deep-layer shear in this area could
support a few cells with small hail or gusty winds. For eastern
areas including the Carolinas and VA, widespread early precipitation
and clouds will likely hamper destabilization.
