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.
