....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Thursday.

....Synopsis...

A progressive upper pattern is expected on Thursday. The upper
trough over the MS Valley will track across the eastern U.S. while
another trough moves inland across the West. The upper ridge between
the two troughs will migrate from the Rockies/Four Corners vicinity
toward the Plains, becoming somewhat less amplified as it does so. A
surface cold front is forecast to be located just offshore from the
Carolinas/Georgia coast into northern FL and the eastern Gulf of
Mexico Thursday morning. The front will develop southward across
central FL through the period.

Isolated to widely scattered thunderstorms will develop along the
front across central FL by early afternoon. While mid/upper 60s
surface dewpoints will contribute to modest instability, poor
midlevel lapse rates and weak vertical shear will limit severe
thunderstorm potential.

Additional isolated thunderstorms will be possible across parts of
coastal CA into the Central Valley. Strong deep-layer westerly flow
and cool midlevel temperatures will support a few lightning flashes.
However, generally cool boundary-layer conditions and meager
instability will preclude severe thunderstorm potential.
