MESOSCALE DISCUSSION 1016
NWS STORM PREDICTION CENTER NORMAN OK
0921 AM CDT MON MAY 31 2004

AREAS AFFECTED...SERN LA/FAR SRN MS/FAR SRN AL/SWRN GA/FL PANHANDLE

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 311421Z - 311515Z

WW MAY BE REQUIRED SOON FOR PORTIONS OF SERN LA...FAR SRN MS...FAR
SRN AL...FL PANHANDLE...AND EWD INTO SWRN GA.

SURFACE HEATING WITHIN A VERY MOIST AIR MASS ACROSS SRN LA EWD TO
SWRN GA/FL PANHANDLE IS RESULTING IN THE DEVELOPMENT OF A MODERATELY
UNSTABLE AIR MASS PER OBJECTIVE ANALYSES.  ADDITIONAL SURFACE
HEATING WILL FURTHER DESTABILIZE THIS AIR MASS WITH STORMS EXPECTED
TO DEVELOP AND/OR RE-INTENSIFY ACROSS SRN AL WSWWD INTO SRN MS TO
SERN LA.  THESE STORMS WILL BE AIDED BY INCREASING DEEP LAYER ASCENT
ALONG A SWD MOVING OUTFLOW BOUNDARY AND INCREASING LARGE SCALE
ASCENT IN THE ENTRANCE REGION OF A WSWLY 75 KT MID-LEVEL JET MOVING
ACROSS THE TN VALLEY INTO THE AFTERNOON.  SUFFICIENT DEEP LAYER
SHEAR FOR SUPERCELLS AND STRAIGHT HODOGRAPHS WITHIN A VERY MOIST AIR
MASS /SURFACE DEWPOINTS IN THE MID-UPPER 70S/ WILL SUPPORT A TORNADO
THREAT...ESPECIALLY ALONG THE SURFACE BOUNDARY.  BOWING SEGMENTS
WITH A DAMAGING WIND THREAT WILL ALSO BE LIKELY.
