NWS STORM PREDICTION CENTER NORMAN OK
1052 PM CDT FRI JUL 08 2016

AREAS AFFECTED...CNTRL AND COASTAL SC / E-CNTRL AND SERN GA

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

VALID 090352Z - 090445Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...AN ISOLATED THREAT FOR WIND DAMAGE DUE TO 40-60 MPH WINDS
WILL EVENTUALLY SPREAD FROM THE PIEDMONT TO THE COAST.

DISCUSSION...RADAR MOSAIC SHOWS RENEWED STORM DEVELOPMENT OVER THE
SAVANNAH RIVER VALLEY LOCATED ON THE SWRN EXTENSION OF A LONG-LIVED
LINEAR MCS.  A 32-KT GUST AT 0343Z WAS MEASURED AT KDNL NEAR THE
GREATER AUGUSTA AREA.  THE AIRMASS DOWNSTREAM OVER E-CNTRL GA EWD TO
THE SC LOWCOUNTRY AND GRAND STRAND IS CONSIDERED VERY MOIST WITH
DEWPOINTS IN THE LOWER-MID 70S AND SURFACE TEMPS IN THE MID 80S AS
OF 03Z.  TEMPS WILL BE SLOW TO COOL THROUGH THE EARLY PART OF THE
OVERNIGHT.  MODIFYING THE 00Z CHS RAOB FOR AREA SURFACE CONDITIONS
YIELDS A VERY UNSTABLE PROFILE WITH 3000 J/KG MLCAPE.  RECENT VAD
DATA FROM KCAE SHOWED STRENGTHENING WNWLY FLOW FROM 25 KT TO 45 KT
IN THE PAST 1-2 HRS.  FLOW FIELDS AT KCLX ARE BEGINNING TO SLOWLY
INTENSIFY TOO WITH 30 KT AT 0.5 KM AGL.  WILL MONITOR SHORT-TERM
TRENDS FOR THE POSSIBILITY FOR ADDITIONAL STORM STRENGTHENING AND
INSTRUMENTED SITES OVER THE SAVANNAH RIVER VALLEY FOR PEAK WIND
GUSTS.
