BOUNDARY
.
SATELLITE ANALYSIS AND TRENDS...LATEST SFC ANALYSIS SHOWS A STATIONARY
BOUNDARY DRAPED NW-SE ACROSS W TX/N AL THEN BECOMING ORIENTED W-E ACROSS
N GEORGIA AT 15Z.  OVER THE LAST 1-2 HRS CONVECTIVE HAS BEEN NOTED
DEVELOPING ACROSS EAST-CENTRAL TN AND N/CENTRAL GA.  A VERY MOISTURE-RICH
LLVL PW PLUME WITH PW VALUES UP TO 2.0” IS SEEN EXTENDING INTO S-CENTRAL
AL/GA PER LATEST GOES SOUNDER AND GPS NETWORK DATA. BASED ON PROFILER
DATA..LLVL 925-850MB FLOW HAS SHOWN A PERSISTENT BACKING TREND OVER PAST
SEVERAL HRS AND BECAUSE OF THIS EXCELLENT LLVL MOISTURE TRANSPORT IS
OCCURRING ACROSS AL/GA/E SC.  TWO MAIN AREAS OF CONCERN FOR HVY RAIN AND
TRAINING OF CELLS ARE ACROSS E-CENTRAL TN AND N-CENTRAL GA/W-CENTRAL SC.
.
IN GA/SC..A RATHER DISTINCT W-E LINE OF CONVECTIVE IS SEEN STRETCHING
FROM CARROLL COUNTY GA INTO AIKEN COUNTY IN SC.  IN LAST 30 MINS CLOUD
TOP TEMPS ASSOCIATED WITH A CELL INVOF CARROLL/COWETA COUNTIES HAS COOLED
BY 28C (-22C AT 1745Z TO -50C AT 1815C).  FURTHER CLOUD TOP COOLING WITH
THIS CELL AND THOSE TO ITS E ARE EXPECTED OVER THE NEXT SEVERAL HRS.
THE CELLS ARE REMAINING RATHER STATIONARY AND THIS IS MOST LIKELY
ASSOCIATED WITH THE BACKING LLVL FLOW.  MOST IMMEDIATE CONCERN WILL BE
FOR HVY RAINS WITH THE CONVECTIONS ACROSS CARROLL/COWETA COUNTIES AND
ANOTHER INTENSE CLUSTER OF CELLS ALONG THE GA/SC BORDER NEAR RICHMOND
COUNTY IN E GA/AIKEN COUNTY IN W SC.  ADDITIONAL REDEVELOPMENT THIS
AFTERNOON ACROSS N-CENTRAL GA SHOULD BE EXPECTED AND WITH THIS TRAINING
OF CELLS OVER THE SAME LOCATIONS COULD RESULT IN SOME FLOODING CONCERNS.
.
IN TN..A SLOW MOVING CELL CURRENTLY LOCATED NEAR WARREN COUNTY IS EXPECTED
TO PRODUCE HVY RAINS OVER NEXT 1 HR.  ADDITIONAL CU/TCU ARE SEEN IN
VIS JUST TO THE WEST OF THIS AREA OF CONVECTION ACROSS CENTRAL TN.
ADDITIONAL CONVECTION IS LIKELY TO DEVELOP THIS AFTERNOON AND THE
LIKELIHOOD FOR CELLS TO REMAIN STATIONARY OR MOVING VERY SLOWLY IS HIGH
JUST E OF THE STATIONARY BOUNDARY.
