ORGANIZING LINE SEGMENT ACROSS PORTIONS OF W-CNTRL GA EXPECTED TO
CONTINUE EWD ALONG AND E OF THE I-75 CORRIDOR. A SMALL BRIEF WINDOW
OF OPPORTUNITY MAY EXIST FOR AN ISOLD BRIEF/WEAK TORNADO OVER THE
DISCUSSION AREA FOR THE NEXT HOUR OR TWO. SEEMINGLY LIMITED
POTENTIAL AND MAGNITUDE OF THREAT PRECLUDE A WW ISSUANCE.
22Z SURFACE MESOANALYSIS PLACES A WAVY FRONT EXTENDING FROM LAMAR
COUNTY ESEWD INTO LAURENS COUNTY GA. RECENT KFFC RADAR IMAGERY
SHOWS AN ORGANIZED SUB-SEVERE SQUALL LINE MOVING EWD FROM MUSCOGEE
COUNTY NEWD TO HENRY COUNTY GA. FURTHER E...STRONG/SEVERE STORMS
HAVE INTENSIFIED AS THEY CROSS/MOVE E OF THE BOUNDARY...BUT MOIST
LOW LEVELS ARE MAINTAINING SUFFICIENTLY HIGH THETA-E AIRMASS.
BACKED LOW LEVEL FLOW IMMEDIATELY ALONG AND BEHIND THE BOUNDARY MAY
HELP CONTRIBUTE TO POSSIBILITY OF A BRIEF/WEAK TORNADO...ESPECIALLY
WITH THE MORE INTENSE UPDRAFTS BEHIND/INVOF THE BOUNDARY AND WITH
THE MORE ORTHOGONAL PORTIONS OF THE SQUALL LINE AS IT INTERACTS WITH
VORTICITY RICH W-E ORIENTED BOUNDARY.
