   ...NO SVR TSTM AREAS FORECAST...
   
   ...MIDDLE ATLANTIC/SOUTH FL...
   
   CONVECTION IS INCREASING OVER THE WARMER GULF STREAM...JUST OFFSHORE
   OF CAROLINA COAST...IMMEDIATELY AHEAD OF DEVELOPING SFC LOW.  A
   NARROW WEDGE OF MODIFIED BOUNDARY LAYER AIR HAS SPREAD ACROSS THE
   OUTER BANKS REGION WHERE LOW LEVEL FLOW HAS VEERED TO ESELY
   DIRECTION WITH NEAR 60 SFC DEW POINTS. IT APPEARS THIS LINE OF
   THUNDERSTORMS WILL CONTINUE TO DEVELOP NNEWD AND BRUSH ERN MOST
   PORTIONS OF NC BEFORE ACTIVITY MOVES TOTALLY OVER WATERS.
   
   FARTHER SOUTH...MARITIME TROPICAL AIRMASS HAS RETURNED TO SRN
   PENINSULA AHEAD OF APPROACHING THUNDERSTORM CLUSTERS.  12Z SOUNDING
   FROM MFL INDICATES LOW LEVEL WARM ADVECTION PERSISTS...WITH
   APPROACHING UPPER LEVEL TROUGH WELL DEPICTED ABOVE 700MB.  THIS
   FEATURE WILL ENHANCE CONVECTIVE POTENTIAL ACROSS THE REMAINDER OF FL
   PENINSULA THIS MORNING.  SFC-BASED INSTABILITY IS NOT EXPECTED TO
   BECOME SUFFICIENT ENOUGH TO WARRANT MORE THAN MARGINALLY SEVERE
   CONVECTION CAPABLE OF GENERATING GUSTY WINDS...ESPECIALLY GIVEN THE
   DEEP LAYER LAPSE RATES ON THE ORDER OF 6 C/KM.
   
   
   ...CA...
   
   WARM CONVEYOR BELT PRECIPITATION WITH EMBEDDED LINE OF CONVECTION IS
   SAGGING SEWD ACROSS THE SACRAMENTO VALLEY INTO THE NRN PORTIONS OF
   THE SAN JOAQUIN VALLEY.  POST FRONTAL DESTABILIZATION WILL PROVE
   DIFFICULT DESPITE THE STEEP LAPSE RATES AS THERMODYNAMIC PROFILES
   ARE QUITE COLD WITH MARGINAL SFC DEW POINTS.  IT APPEARS CONVECTION
   WILL INCREASE AS UPPER TROUGH MOVES INLAND...HOWEVER ACTIVITY WILL
   REMAIN SHALLOW AND LIKELY RESULT IN A FEW BRIEF INTENSE STORMS WITH
   SMALL HAIL.
