Area forecast discussion, Jul 13, 3:31 PM EDT, 29 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 331 PM EDT SUN JUL 13 2003 FOR THE SHORT TERM...MULTICELLULAR CLUSTERS OF THUNDERSTORMS WILL CONTINUE TO DEVELOP AND MOVE EAST ACROSS THE WESTERN CAROLINAS WELL INTO THE EVENING HOURS. EXPECT A FEW MORE SEVERE THUNDERSTORMS GIVEN A FAVORABLE ENVIRONMENT OF COOL TROF AT MID LEVELS AND LOW LEVEL CONVERGENCE ALONG AND SOUTH OF SURFACE BOUNDARY CUTTING EAST TO WEST ACROSS THE FORECAST AREA. THE CONVECTION MAY PERSIST THROUGH THE OVERNIGHT HOURS AS IT SHIFTS OFF TO THE EAST AS THE SYNOPTIC ENVIRONMENT SHOULD CONTINUE TO SUPPORT IT...WITH SHORT WAVE ROTATING AROUND BOTTOM OF UPPER TROF AND UPPER DIVERGENCE IN RIGHT ENTRANCE REGION OF UPPER JET. ON MONDAY...THE BEST FORCING SHIFTS OFF TO THE EAST...PUTTING THE PIEDMONT IN THE GRADIENT OF PRECIP PROBABILITY WITH CHANCE ACROSS THE MOUNTAINS AND FOOTHILLS AND LIKELY TO OUR EAST. THE FORCING SHOULD DIMINISH LATE IN THE DAY AS ENERGY PULLS OUT OF THE UPPER TROF. AS A RESULT...CONVECTION SHOULD ALSO BE MORE DIURNAL IN NATURE. TUESDAY AND WEDNESDAY SHOULD ALSO FEATURE TYPICAL DIURNAL CONVECTION. HAVE STAYED RELATIVELY CLOSE TO TEMP GUIDANCE THROUGHOUT.
