AREAS AFFECTED...SRN AL/CNTRL GA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 141922Z - 142115Z

TSTMS WILL LIKELY CONTINUE TO DEVELOP ALONG CONVERGENCE BOUNDARY
THROUGH THE AFTERNOON. A MODERATELY UNSTABLE AIRMASS ALONG WITH
MODERATE SPEED SHEAR WILL SUPPORT A THREAT FOR MAINLY LARGE HAIL.
TRENDS ARE BEING MONITORED FOR A POSSIBLE WW IN THE NEXT FEW HOURS.

TSTMS APPEAR TO HAVE INITIATED ALONG AN APPARENT OUTFLOW BOUNDARY
FROM EARLIER CONVECTION...GENERALLY IN AN AXIS BETWEEN MGM AND TOI
ARCING NEWD TOWARDS MCN. AIR MASS HAS DESTABILIZED TO THE S OF THE
OUTFLOW BOUNDARY...ALTHOUGH HINDERED SOMEWHAT BY CONVECTIVE DEBRIS.
TEMPERATURES AROUND 80 AND DEW POINTS AROUND 60 SUPPORT MLCAPES FROM
1000 TO 1500 J/KG PER MODIFIED RUC SOUNDINGS. EOX AND JGX VAD WIND
PROFILERS INDICATE UNIDIRECTIONAL WLY FLOW ACROSS MUCH OF SRN AL
INTO CNTRL GA...WITH ADEQUATE SPEED SHEAR AROUND 35 TO 45 KTS. AS
STORMS PROPAGATE EWD INTO THE MORE UNSTABLE AIR MASS S OF THE
OUTFLOW BOUNDARY...POTENTIAL FOR LARGE HAIL WILL INCREASE THROUGH
THE AFTERNOON HOURS.
