(ISSUED ISSUED BY NATIONAL WEATHER SERVICE COLUMBIA SC) SHORT TERM (REST OF THIS AFTERNOON THROUGH SATURDAY)... DIFFERENTIAL HEATING IN THE MOUNTAINS AND AN INCREASE IN MOISTURE AHEAD OF THE BACK DOOR FRONT SHOULD CAUSE SCATTERED THUNDERSTORMS LATE THIS AFTERNOON. THE MAIN THREAT FROM THE THUNDERSTORMS APPEARS TO BE HAIL. SHEAR APPEARS WEAK...BUT INSTABILITY MODERATE WITH FAVORABLE WET-BULB ZERO HEIGHTS. THE BACK DOOR FRONT SHOULD MOVE INTO THE FORECAST AREA TONIGHT. CONVERGENCE ASSOCIATED WITH THE FRONT AND UPSLOPE FLOW BEHIND THE FRONT SHOULD LEAD TO SHOWERS AND THUNDERSTORMS BUT COVERAGE SHOULD BE LIMITED BY THE UPPER-LEVEL RIDGING. PLAN TO KEEP POPS IN THE CHANCE CATEGORY. HEAVY RAIN MAY OCCUR BECAUSE OF SLOW MOVEMENT...BUT PRECIPITABLE WATER IS NOT TOO HIGH (NEAR 1.25 INCHES) SO RAINFALL WILL PROBABLY NOT BECOME EXCESSIVE. DO NOT BELIEVE A FLOOD WATCH IS NEEDED AT THIS TIME. THE UPPER-LEVEL RIDGING AND DIURNAL TIMING SHOULD KEEP INSTABILITY WEAK SO SEVERE THUNDERSTORMS WILL PROBABLY NOT OCCUR OVERNIGHT. THE FRONT LINGERING NEAR THE FORECAST AREA FRIDAY SUPPORTS CONTINUED SHOWERS AND THUNDERSTORMS...BUT COVERAGE STILL APPEARS LIMITED BY UPPER-LEVEL RIDGING AND CLOUDINESS LIMITING INSTABILITY.
