Day 1 Convective Outlook  

NWS Storm Prediction Center Norman OK

1049 AM CDT Thu Mar 19 2026



Valid 191630Z - 201200Z



...NO THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Thunderstorms are not forecast across the U.S. today or tonight.



...Synopsis...



Surface high pressure over the Southeast and a dry airmass over the

Gulf Basin will result in a persistent stable environment east of

the Rockies, precluding thunderstorm activity. A drier airmass is

also expected across south FL compared to previous days. Offshore

thunderstorms may approach the east-central FL coast tonight.

However, meager instability and nebulous forcing will likely limit

any thunderstorm coverage on land to less than 10 percent.
