Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1036 AM CDT Wed Mar 18 2026
Valid 181300Z - 191200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible today across far south
Florida.
...Synopsis...
A substantial upper high and attendant ridge is apparent in morning
water vapor imagery over the western U.S. Further east, a stalled
front is noted across the Bahamas and Florida Straits. Surface high
pressure in the wake of the frontal boundary across the Southeast
will maintain offshore trajectories and a dearth of boundary layer
moisture. This will preclude thunderstorm activity across most of
the CONUS.
Some lingering low-level moisture and weak elevated instability may
support a couple of thunderstorms over far south FL and portions of
the Keys today, though most activity will remain offshore.
