AREAS AFFECTED...PORTIONS ERN LA...NRN AL...MUCH OF MS.

CONCERNING...CONVECTIVE TRENDS 

VALID 260623Z - 260830Z

GEN TSTM POTENTIAL WILL INCREASE ACROSS CORRIDOR FROM NRN AL TO SWRN
MS THROUGH AT LEAST 9Z.  MOST OF THIS ACTIVITY SHOULD REMAIN BELOW
SEVERE LIMITS...HOWEVER OCCASIONAL DAMAGING GUSTS AND MRGLLY SEVERE
HAIL ARE POSSIBLE.  WW NOT ANTICIPATED ATTM.

CONVECTION ACROSS THIS REGION WILL OCCUR IN ASSOCIATION WITH LOOSELY
ORGANIZED TSTM COMPLEXES NOW MOVING ESEWD FROM SWRN TN AND NWRN MS
TOWARD N-CENTRAL AL...AS WELL AS MOVING EWD FROM WW 253 ACROSS MS
RIVER FROM ERN LA INTO WRN MS. ADDITIONAL DEVELOPMENT ALSO IS
POSSIBLE ACROSS THIS REGION.  SFC MESOANALYSIS SHOWS OUTFLOW
BOUNDARY FROM EARLIER MCS FROM FL PANHANDLE INTO NRN GULF...THEN
NWWD ACROSS EXTREME SE TX AND EXTREME SWRN LA. NRN PORTION OF
MCS-OVERTURNED AIR ALOFT APPEARS TO LIE NEAR BHM-GWO LINE.  MODIFIED
RAOBS AND RUC SOUNDINGS INDICATE ELEVATED MUCAPES AROUND 500 J/KG
ACROSS PORTIONS CENTRAL/SRN MS...TRENDING UPWARD TO 1500-2000 J/KG
RANGE WITH NRN EXTENT INTO NRN PORTIONS MS/AL WHERE EARLIER MCS DID
NOT AFFECT AIR MASS ALOFT AS MUCH.  GIVEN STEEPER LAPSE RATES OVER
NRN PORTIONS MS/AL...AND SOMEWHAT LARGER EFFECTIVE SHEAR PROFILES
WITH NRN EXTENT...HAIL POTENTIAL WILL BE LARGER WITH ACTIVITY IN
THOSE AREAS THAN WITH COMPLEX MOVING EWD FROM LA.
