AREAS AFFECTED...NRN AND CENTRAL GA/SC/PARTS OF SRN NC
CONCERNING...SEVERE THUNDERSTORM WATCH 579...
VALID 062059Z - 062200Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 579
CONTINUES.
MID AFTERNOON SURFACE ANALYSIS SHOWED A BOUNDARY EXTENDING FROM SERN
VA SWWD THROUGH CENTRAL NC INTO THE SC PIEDMONT...AND THEN WNWWD
THROUGH NRN GA TO FAR NRN AL TO NERN MS. REGIONAL RADAR IMAGERY
INDICATED THAT MOST OF THE TSTM ACTIVITY HAS REMAINED CONFINED TO
THE VICINITY OF THIS BOUNDARY AND WITH ACTIVITY THAT HAD DEVELOPED
AND MOVED E/SEWD OFF THE HIGHER TERRAIN IN THE NWRN EXTENT OF WW
579. CONVECTIVE OUTFLOW INTERACTIONS WILL ALSO AID IN NEW TSTM
DEVELOPMENT AS THE AIR MASS ALONG AND S OF THE PRIMARY FRONTAL ZONE
IS MODERATELY-VERY STRONGLY UNSTABLE /MLCAPE 2000-2500+ J PER KG/.
STRONG WIND GUSTS WILL REMAIN THE PRIMARY THREAT THROUGH THE REST OF
THE AFTERNOON INTO THE EARLY EVENING GIVEN THE HIGH MOISTURE CONTENT
AIR MASS RESULTING IN WATER LOADING OF DOWNDRAFTS. ALSO...ANY COLD
POOL DEVELOPMENT /E.G. CURRENTLY LOCATED OVER NERN GA INTO FAR WRN
SC WHERE SURFACE TEMPERATURES ARE IN THE 70S AS COMPARED TO MID 90S
OVER EAST CENTRAL GA AND CENTRAL SC/ SHOULD ENHANCE THE DOWNSTREAM
WIND THREAT.
