Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1014 AM CST Sun Jan 18 2026
Valid 181630Z - 191200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast across the U.S. today or
tonight.
...Discussion including South Florida...
A longwave trough will remain prominent east of the Rockies, with an
embedded shortwave trough crossing the Southeast, in addition to
multiple clipper-type troughs over the Upper Midwest. The potential
for isolated thunderstorms will exist across the far southern
Florida Peninsula and near the Keys to the south of a cold front,
somewhat enhanced by diurnal heating and a moist pre-frontal air
mass with lower 70s F surface dewpoints. However, most of the
thunderstorm potential should focus offshore, and that will
particularly be the case by late today as low-level winds veer and
the front progresses offshore.
