...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated non-severe thunderstorms will be possible today in south
Florida and in California.

Latest water vapor loop shows multiple shortwave troughs affecting
the US today, but relatively dry/stable conditions will limit the
risk of thunderstorm activity to small parts of south FL and central
CA.  In both areas, large-scale forcing is weakening through the day
and the risk of deep convection will diminish through the afternoon.
 No severe storms are expected.
