...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE MDT RISK FROM
THE FL PANHANDLE...NWD INTO IND/OH...

...CENTRAL GULF STATES/OH VALLEY...

PERSISTENT SHOWERS/TSTMS ACROSS NERN AL/NRN GA HAVE SLOWED NWD
RETURN OF MARITIME AIRMASS INTO THE NRN GULF STATES.  A NARROW WEDGE
OF HIGHER THETA-E AIR IS ADVECTING WEST-NORTH BEHIND THIS BUBBLE OF
STABLE AIR...IMMEDIATELY AHEAD OF COLD FRONT ADVANCING ACROSS NCNTRL
AL.  SFC WIND SHIFT APPEARS RESPONSIBLE FOR AIDING MORE LINEAR BAND
OF THUNDERSTORMS THAT ARE GRADUALLY DEVELOPING SWD INTO HIGHER
INSTABILITY.  OF MORE CONCERN ARE THE DISCRETE SUPERCELLS ALONG SRN
END OF THIS ACTIVITY...AND WITHIN THE WARM SECTOR OVER CNTRL AL. 
THIS ACTIVITY HAS STRUGGLED AT TIMES...ALTHOUGH CONTINUED
SUNSHINE/HEATING SHOULD AID FURTHER DESTABILIZATION.  SHEAR PROFILES
REMAIN VERY SUPPORTIVE FOR SUPERCELL STRUCTURES...AND WITH CONTINUED
MOISTENING BOUNDARY LAYER...TORNADO THREAT REMAINS DISTINCT WITH
STRONGER UPDRAFTS.

FARTHER NORTH INTO THE OH VALLEY...MOIST ADIABATIC PROFILES AND
MARGINAL INSTABILITY SEEM TO BE THE MAIN IMPEDIMENT FOR WIDESPREAD
SEVERE THUNDERSTORM EVENT ACROSS THIS REGION.  EVEN SO...SUFFICIENT
INSTABILITY CURRENTLY EXISTS FOR THUNDERSTORM DEVELOPMENT...AS
EVIDENT BY LIGHTNING DATA INTO KY/SERN IND.  DAMAGING WINDS APPEAR
THE MAIN SEVERE THREAT IF BOW-TYPE STRUCTURES CAN MATERIALIZE.
