AREAS AFFECTED...MUCH OF SOUTHERN GEORGIA
CONCERNING...SEVERE THUNDERSTORM WATCH 285...
VALID 181418Z - 181615Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 285
CONTINUES.
SUMMARY...A CORRIDOR OF SEVERE WIND POTENTIAL MAY EXTEND SOUTHEAST
OF WW 285, WITH ISOLATED HAIL OVER SOUTHERN AREAS. A NEW WATCH MAY
BE NEEDED DOWNSTREAM SOON.
DISCUSSION...AN ORGANIZED CONVECTIVE SYSTEM CONTINUES TO MOVE
RAPIDLY SOUTHEASTWARD OVER WEST-CENTRAL GA. THIS SYSTEM IS NEAR THE
INSTABILITY GRADIENT, WITH EXTENDS ALL THE WAY TO THE COAST. THE
MORNING SOUNDINGS SHOW SUBSTANTIAL MID LEVEL WINDS ALONG WITH GOOD
LAPSE RATES ALOFT AND RELATIVELY WEAK LOW-LEVEL WINDS. THIS APPEARS
FAVORABLE FOR FORWARD PROPAGATION AND CONTINUED DAMAGING WIND THREAT
FOR A FEW HOURS.
IN ADDITION, GIVEN THAT THE STRONGEST INSTABILITY IS ON THE SOUTHERN
PERIPHERY OF THIS CONVECTIVE SYSTEM, AT LEAST A GRADUAL INCREASE IN
STORM CORES IS POSSIBLE ALONG THE SOUTH END WHICH MAY ALSO CONTAIN
LARGE HAIL, ESPECIALLY AS BOUNDARY LAYER HEATING OCCURS.
