AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 324 PM EDT SAT MAY 20 2006 .SHORT TERM /TONIGHT THROUGH TUESDAY/... CONVECTION HAS BLOSSOMED RAPIDLY OVER THE SOUTHWEST CWFA IN MODERATELY UNSTABLE ENVIRONMENT OVER THE AREA. LOW LEVEL WIND HAS YET TO MAKE THE TURN TO A WESTERLY DIRECTION...SO MIXING WAS MINIMIZED IN THE SOUTH DESPITE NEARLY FULL SUN AND LAPSE RATES HAVE BECOME QUITE STEEP. WIND SHEAR STILL SUFFICIENT FOR SUPERCELLS THROUGH 21Z OR SO...THEN FORECAST DATA SUGGESTS WEAKENING SHEAR BUT STILL A HAIL THREAT. UPSTREAM...A CONVECTIVE COMPLEX HAS DEVELOPED OVER SOUTHERN TENNESSEE...AHEAD OF A VORT CENTER. THIS COMPLEX SHOULD OVERSPREAD THE FAR WESTERN MOUNTAINS...NORTHEAST GEORGIA AND THE WESTERN HALF OF THE UPSTATE THROUGH THROUGH EARLY EVENING...THEN PERHAPS TREK A BIT TO THE EAST. NAM AND GFS BOTH BREAK UP THE PRECIP FIELD IN FAVORED-DOWNSLOPE LOCATIONS...THEN ORGANIZE ANOTHER CONVECTIVE CLUSTER OVER THE EASTERN ZONES AS THE COLD FRONT FROM UP NORTH SAGS SOUTH. WE WILL FEATURE HIGH CHANCE TO LIKELY POPS IN THE SOUTH...TRENDING TO ISOLATED NORTH OF INTERSTATE 40. UPPER AIR ANALYSIS THIS MORNING SHOWED A TROF UPSTREAM THAT IS EXPECTED TO MOVE IN OUR DIRECTION OVERNIGHT AND SUNDAY. AT THE SAME TIME...MODELS SUGGEST A SECONDARY FRONT OR SURFACE BOUNDARY WILL BACK DOOR FROM THE MID ATLANTIC STATES AS ANOTHER LOBE OF DPVA AFFECTS THE REGION WITH SHORTWAVE. AGAIN...IT APPEARS THE SOUTHWEST MOUNTAINS...NORTHEAST GEORGIA AND THE UPSTATE WILL HAVE GREATEST COVERAGE OF PRECIPITATION. AT THE SAME TIME...FRONT CURRENTLY ATTEMPTING TO DROP SOUTH ACROSS THE REGION WILL BE STATIONARY JUST TO OUR SOUTH. ANY OSCILLATION OF THE FEATURE BACK NORTHWARD COULD RESULT IN SLIGHTLY BETTER COVERAGE OVER THE SOUTHERN CWFA. WE WILL PLAN CHANCE POPS FOR THE AFOREMENTIONED AREAS...AND LIMIT TO ISOLATED OR LESS FOR THE MORE NORTHERN AREAS...WHERE RETURN FLOW MAY NOT BE AS GREAT. ANOTHER REINFORCING COLD FRONT WILL MOVE SOUTHWARD INTO NORTH CAROLINA SUNDAY NIGHT...AS DIVERGENCE IN THE RIGHT ENTRANCE REGION OF THE UPPER JETLET CROSSES THE SOUTHERN APPALACHIANS. TIMING OF H5 SHORTWAVES VARIES WIDELY FROM MODEL TO MODEL FOR THE SUN NIGHT THROUGH MON PERIOD...BUT CONSENSUS BRINGS THE BEST UPPER SUPPORT TO THE SRN APPALACHIANS AROUND 12Z MONDAY. THE COLD FRONT WILL CONTINUE TO PROVIDE A FOCUSING MECHANISM FOR SCATTERED CONVECTION AS IT MOVES SOUTH ACROSS THE REGION ON MONDAY...THEN SLIP SOUTH OF THE AREA ON TUESDAY. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... AN UPPER LEVEL LOW PRES SYSTEM IS EXPECTED TO DEVELOP IN THE MIDWEST ON THURSDAY...AND SWING SLOWLY THROUGH THE CENTRAL APPALACHIANS THROUGH NEXT WEEKEND. PRECIPITATION CHANCES WILL RAMP UP ACCORDINGLY THU THROUGH SAT...AS A SURFACE FRONT REMAINS STALLED ACROSS THE REGION. && .AVIATION... DELAY OF SURFACE FRONT PUSHING SOUTH ACROSS THE AREA HAS RESULTED IN SOUTH TO SOUTHWEST SURFACE WINDS IN THE FOOTHILLS AND PIEDMONT. WIND SHOULD VEER TO MORE OF A WESTERLY DIRECTION AS THE FRONT SAGS SOUTH PAST KHKY LATE THIS AFTERNOON...BUT MAY MAINTAIN SOME SEMBLENCE OF SOUTHWEST CHARACTERISTICS AS SHORTWAVE ENERGY APPROACHES FROM THE WEST. TSRA ORGANIZING NOW OFF TO THE WEST. WE INCLUDED A TEMPO GROUP AT KAND FOR MVFR VISIBILITY RESTRICTIONS IN THE 20Z TO 23Z TIME FRAME...WITH VCSH INCLUDED FROM LATE AFTERNOON TO 00Z AT ALL OTHER SITES EXCEPT FOR KHKY. AFTER THIS EVENING...A GENERAL LIGHT WEST WIND SHOULD DOMINATE. THERE WILL LIKELY BE A PERIOD OF VARIABLE WIND DIRECTION WITH LIGHT SPEEDS LATE TONIGHT THROUGH THE EARLY OUTLOOK PERIOD. THE FINAL HOURS OF THE OUTLOOK PERIOD AGAIN FEATURE WEST WINDS AROUND 6 TO 8 KTS...WITH VFR CEILINGS. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE.
