...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not forecast through tonight.

... 01Z ...

Showers and the occasional thunderstorm will be possible this
evening along and south of a surface front stretched from the
Carolinas southwest toward the upper-Gulf coast of Texas. Limited
instability should preclude any severe potential.

Overnight a secondary cold front will move south into the southern
Plains. Cool surface temperatures and moist vertical profiles will
limit overall instability, but enough elevated instability may
develop to support an occasional thunderstorm.

The severe potential will remain low through the forecast period.
