VALID 271200Z - 281200Z  
 
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF  
THE CAROLINAS AND EASTERN GEORGIA...  
   
..SUMMARY
 
 
THUNDERSTORMS ASSOCIATED WITH A MARGINAL WIND DAMAGE THREAT WILL BE  
POSSIBLE THURSDAY AFTERNOON ACROSS PARTS OF THE CAROLINAS AND FAR  
EASTERN GEORGIA.  
 
...EASTERN AND SOUTHERN NORTH CAROLINA/SOUTH CAROLINA/FAR EASTERN  
GEORGIA...  
AN UPPER-LEVEL TROUGH WILL MOVE SLOWLY EASTWARD ACROSS THE  
NORTH-CENTRAL STATES ON THURSDAY AS SOUTHWEST MID-LEVEL FLOW REMAINS  
ALONG THE ATLANTIC SEABOARD. AT THE SURFACE, A COLD FRONT IS  
FORECAST TO MOVE SOUTHEASTWARD ACROSS THE CAROLINAS WITH THE FRONT  
EXTENDING SOUTHWESTWARD INTO THE CENTRAL GULF COAST STATES. SURFACE  
DEWPOINTS AHEAD OF THE FRONT IN THE LOWER 70S F MAY ENABLE A POCKET  
OF MODERATE INSTABILITY TO DEVELOP ALONG THE COASTAL PLAINS OF THE  
CAROLINAS AND EASTERN GEORGIA AROUND MIDDAY. SURFACE HEATING AND  
INCREASED LOW-LEVEL CONVERGENCE ALONG THE FRONT SHOULD RESULT IN  
SCATTERED THUNDERSTORM DEVELOPMENT. 0-6 KM SHEAR OF 25 TO 35 KT  
ALONG WITH STEEP LOW-LEVEL LAPSE RATES, EVIDENT ON FORECAST  
SOUNDINGS, MAY BE ENOUGH FOR A MARGINAL WIND DAMAGE THREAT DURING  
THE AFTERNOON.
