AREAS AFFECTED...CENTRAL GEORGIA
CONCERNING...SEVERE THUNDERSTORM WATCH 462...
VALID 260344Z - 260545Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 462
CONTINUES.
SUMMARY...OUTFLOW BOUNDARIES PUSHING INTO AN UNSTABLE ENVIRONMENT
WILL PROMOTE AN INCREASE IN THUNDERSTORM COVERAGE OVER THE NEXT FEW
HOURS. TRANSIENT, BUT STRONG THUNDERSTORMS WILL SUPPORT DAMAGING
DOWNBURST WINDS AND ISOLATED LARGE HAIL.
DISCUSSION...THUNDERSTORM COVERAGE CONTINUES TO SLOWLY INCREASE
ACROSS CENTRAL GA AS TWO OUTFLOW BOUNDARIES - ONE ASSOCIATED WITH AN
MCS MOVING ACROSS EASTERN GA, AND ANOTHER PUSHING NORTH OUT OF A
CONVECTIVE CLUSTER ORIGINATING IN THE FL PANHANDLE/SOUTHWEST GA -
CONTINUE TO PUSH INTO A VERY UNSTABLE AIR MASS. BASED ON THE 00 UTC
FFC SOUNDING, MID-LEVEL LAPSE RATES ON THE ORDER OF 7.5 C/KM RESIDE
OVER THE REGION, AND LITTLE IN THE WAY OF CONVECTIVE OVERTURNING HAS
OCCURRED THUS FAR. BASED ON SURFACE OBSERVATIONS, NOCTURNAL COOLING
HAS RESULTED IN A RELATIVELY SHALLOW STABLE LAYER NEAR THE SURFACE,
BUT THE DEPTH/INTENSITY OF THE OUTFLOWS WILL CONTINUE TO BE
SUFFICIENT TO LIFT SURFACE-BASED PARCELS TO THEIR LFCS. AS SUCH,
ADDITIONAL THUNDERSTORM DEVELOPMENT IS ANTICIPATED ACROSS CENTRAL
GA. WEAK DEEP LAYER SHEAR IS PROMOTING TRANSIENT CELLS/CLUSTERS WITH
THE POTENTIAL FOR DAMAGING DOWNBURSTS AND PERHAPS SPORADIC LARGE
HAIL. THE SEVERE THREAT WILL BE LOCALLY MAXIMIZED WHERE THE TWO
OUTFLOW BOUNDARIES CONVERGE, WHICH BASED ON RECENT STORM TRACKS,
WILL LIKELY OCCUR IN THE VICINITY OF THE I-75 CORRIDOR IN THE COMING
HOURS.
