MESOSCALE DISCUSSION 1289
NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...CNTRL/E-CNTRL GA...SW SC

CONCERNING...SEVERE THUNDERSTORM WATCH 387...

VALID 031735Z - 031830Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 387
CONTINUES.

SUMMARY...SOME INCREASE IN CONVECTIVE INTENSITY IS POSSIBLE ACROSS
PORTIONS OF SWRN SC AS THE CURRENT LINE OF STORMS CONTINUES SEWD.
PRIMARY SVR THREAT IS DAMAGING WIND GUSTS.

DISCUSSION...17Z CHS RAOB REVEALS A MODERATELY UNSTABLE ENVIRONMENT
DOWNSTREAM FROM THE LINE OF TSTMS CURRENTLY MOVING THOUGH FAR
E-CNTRL GA AND SW SC. WIND SPEEDS HAVE SHOWN LITTLE CHANGE FROM THE
12Z SOUNDING WITH A LAYER OF MODERATE WLY FLOW STILL PRESENT BETWEEN
1 AND 4 KM. SLIGHTLY STRONGER MID-LEVEL WINDS WERE SAMPLED BY RECENT
FFC VAD PROFILES WITH WINDS FROM 40 TO 50 KT IN THE 1 TO 4 KM LAYER.
THE EXPECTATION IS FOR THESE SLIGHTLY HIGHER WIND SPEEDS TO CONTINUE
EWD AND...WHEN COUPLED WITH THE MODERATE INSTABILITY
DOWNSTREAM...FOSTER INCREASED CONVECTIVE INTENSITY ALONG THE LEADING
EDGE OF THE SEWD PROGRESSING COOL POOLS /ONE COOL POOL IS ASSOCIATED
WITH THE CLUSTER CURRENTLY ENTERING WILKINSON AND WASHINGTON
COUNTIES IN GA AND THE OTHER FARTHER SE FROM SCREVEN COUNTY GA NEWD
TO BERKELEY COUNTY SC/. AS SUCH...PRECIP LOADING AND
FORWARD-PROPAGATION WILL CONTINUE POSE A THREAT FOR DAMAGING WIND
GUSTS ACROSS PORTIONS OF WW 387.
