VALID 261449Z - 261645Z

AREA IS BEING MONITORED FOR ADDITIONAL WW.

SHORT WAVE...PROGRESSING THROUGH BASE OF LARGER-SCALE AMPLIFYING
UPPER TROUGH OVER THE MISSISSIPPI VALLEY...APPEARS TO BE PROVIDING
FORCING FOR ONGOING CONVECTIVE LINE ACROSS WEST CENTRAL ALABAMA/
CENTRAL MISSISSIPPI.  AS LINE CONTINUES EAST OF THE INTERSTATE 59
CORRIDOR NEXT FEW HOURS...THERE APPEARS TO BE INCREASING POTENTIAL
FOR INTENSIFICATION...WITH RISK FOR DAMAGING WINDS IN ADDITION TO
LARGE HAIL.

COOL MID-LEVEL AIR MASS IS ALREADY PRESENT ACROSS THE CENTRAL/
EASTERN GULF COAST REGION...WITH FURTHER COOLING LIKELY AS BOUNDARY
LAYER POSSESSING MID 50S+ DEW POINTS BEGINS TO WARM.  BREAKS IN
CLOUD COVER ARE ALREADY PRESENT IN BROAD CORRIDOR FROM MOBILE TO
MONTGOMERY...WHICH SHOULD ALLOW SUFFICIENT INSOLATION FOR MIXED
LAYER CAPE IN EXCESS OF 1000 J/KG BY 18-20Z.

AS BOUNDARY LAYER DESTABILIZES...ONGOING CONVECTIVE LINE SHOULD
INTENSIFY...WITH WEAK CAP ALSO ALLOWING MORE ISOLATED CONVECTIVE
DEVELOPMENT ACROSS SOUTHERN/EASTERN ALABAMA...WHERE SHEAR PROFILES
WILL REMAIN FAVORABLE FOR SUPERCELLS.
