   ...DAMAGING WINDS LIKELY...POSSIBLE TORNADOES IN ATLANTA METRO AREA
   0145-0300Z...
   
   SQUALL LINE CONTINUES TO DISCRETELY PROPAGATE AS NEW CELLS DEVELOP
   IMMEDIATELY AHEAD OF THE COLD POOL...EFFECTIVELY RESULTING IN A
   FASTER TRANSLATION ESE.  EXTRAPOLATION INCORPORATING THIS SCENARIO
   SUGGESTS PRIMARY SQUALL LINE ARRIVING IN NW METRO ATLANTA 0145-0200Z
   AND THE REMAINDER OF ATLANTA...INCLUDING HARTSFIELD INTERNATIONAL
   AIRPORT...0230-0330Z.
   
   00Z PEACHTREE CITY SOUNDING EXHIBITED ONLY 300 J/KG MLCAPE...BUT
   RAPID SFC MOISTURE TRANSPORT NWD INTO THE METRO AREA WILL OCCUR AS
   EVIDENCED BY NEARLY 5 DEG F DEW POINT RISE AT NEWNAN GA.  THIS WILL
   INCREASE BUOYANCY AND COMBINATION OF STRONG COLD POOL DYNAMICS WILL
   MAINTAIN STRONG TSTMS ACROSS NWRN GA.
   
   DAMAGING WINDS APPEAR TO BE THE PRIMARY SVR THREAT IN NW GA THROUGH
   THE EVENING AS CONVECTIVE MODE REMAINS LINEAR.  HOWEVER...AN
   EMBEDDED SUPERCELL TORNADO CANNOT BE RULED OUT AS FLOW IN THE
   0.5-1KM LAYER CONTINUES TO INCREASE...BOOSTING SRH AMIDST STRONG
   DEEP LAYER SHEAR.  HIGHER THREATS FOR TORNADOES WILL EXIST ACROSS
   CNTRL AL INTO WCNTRL GA SOUTH OF ATLANTA.
