AREAS AFFECTED...PARTS OF GA

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 191849Z - 192045Z

CONVECTIVE LINE CONTINUES MOVING ACROSS WRN GA AND THE FL PANHANDLE
ATTM. WHILE AN ISOLATED DAMAGING GUST WILL BE POSSIBLE THIS
AFTERNOON...THREAT SHOULD REMAIN LIMITED AND WW ISSUANCE APPEARS
UNLIKELY ATTM.

DAYTIME HEATING CONTINUES ACROSS THE SERN HALF OF GA...AHEAD OF
ONGOING CONVECTIVE LINE. DESPITE THIS...AND DEWPOINTS INTO THE LOW
60S...VERY WEAK MID-LEVEL LAPSE RATES WILL CONTINUE TO HINDER ANY
APPRECIABLE DESTABILIZATION. ALONG WITH 16Z ATLANTA GA RAOB AND
MODEL FORECAST SOUNDINGS...LACK OF OBSERVED LIGHTNING CONFIRMS THIS
LACK OF INSTABILITY.

ANY THREAT FOR DAMAGING WINDS ACROSS THIS REGION IS THE RESULT OF A
VERY STRONG DEEP-LAYER WIND FIELD IN PLACE ACROSS THE AREA. THE 16Z
ATLANTA RAOB REVEALED 50 TO 60 KT LOW-LEVEL JET AND 85 KT SWLYS AT
H5...WITH EVEN STRONGER MID-LEVEL FLOW PER RECENT VWPS. THUS --
WHILE LACK OF INSTABILITY WILL STRONGLY HINDER SEVERE
THREAT...STRENGTH OF WIND FIELD SUGGESTS THAT A POTENTIAL FOR A
LOCALLY-DAMAGING GUST OR TWO WILL LINGER THROUGH THE AFTERNOON.
