Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1059 AM CDT Sun Apr 19 2026
Valid 191630Z - 201200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast today.
...Synopsis...
A shortwave trough currently approaching Baja California will
provide increasing large-scale forcing for ascent over Mexico and
south/west TX today. This will lead to scattered thunderstorms
through the period.
Other isolated afternoon thunderstorms are expected ahead of a
frontal band affecting New England and eastern NC, beneath cold air
aloft in the Lower Great Lakes region, and over south FL. In all of
these areas, weak instability and/or limited vertical shear will
preclude a risk of organized severe storms.
