1115 AM CDT Mon Mar 23 2026
Valid 231630Z - 241200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible today from southeast Georgia to
the coastal Carolinas.
...Coastal Carolinas/Georgia...
A large upper trough continues to track eastward across the lower
Great Lakes and into New England today, while the associated surface
cold front sags across the southeast states. As the front
approaches the more moist and marginally unstable offshore air mass,
showers and a few thunderstorms will become more numerous. This
process will occur late this afternoon, and might result in a strong
storm or two along the immediate coast of NC before activity moves
out to sea. Small hail or gusty winds are possible, but the overall
severe threat seems too low to warrant probabilities at this time.
