NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at May 20, 1:23 AM EST, 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 223 AM EDT SAT MAY 20 2006 .SHORT TERM /TODAY THROUGH SUNDAY/... NAM AND WRF WERE RIGHT ON TARGET DEVELOPING WIDESPREAD CONVECTION OVER EASTERN TN AND WRN NC EARLY THIS MORNING. AS THE LLVL FLOW VEERS MORE OUT OF THE WEST AND INCREASES...CONVECTION SHOULD BE FAIRLY PROGRESSIVE...THOUGH THERE IS NO SAYING JUST HOW LONG STORMS WILL CONTINUE TO DEVELOP UPSTREAM. THE GENERAL MODEL CONSENSUS IS THAT CONVECTION WL TAPER OFF AND MOVE EAST OF THE CWFA BETWEEN 12-15 UTC...AND HIGHS POPS WILL PROBABLY BE NEEDED OVER THE NC FOOTHILLS AND PIEDMONT EARLY INTO THE FIRST PERIOD TODAY (THAT IS...AFTER 6 AM EDT). RECENTLY THERE HAS BEEN A TREND FOR CLOUD TOPS TO COOL OVER ERN TN WHILE THE REFLECTIVITY IN THE CONVECTIVE CORES HAS BEEN DECREASING. THIS APPEARS TO BE A SIGN THAT THE ATMOSPHERE IS BECOMING MORE MOIST IN THE VICINITY OF THE TRAINING CELLS. THIS WILL TEMPER THE SEVERE THREAT BUT WILL RESULT IN HEAVIER RAIN...AND AN ISOLATED FLASH FLOODING THREAT COULD DEVELOP OVER THE NEXT FEW HOURS. DURING THE AFTERNOON HOURS SURFACE BASED CAPE ON THE NAM AND WRF RISES TO AROUND 2500 J/KG OVER THE UPSTATE AND NE GA...WITH DOWNSLOPE RESULTING IN LOWER DEWPOINTS INTO THE NORTH CAROLINA FOOTHILLS AND PIEDMONT. WITH MODERATE TO STRONG SPEED SHEAR...EXPECT THAT STORMS WILL DEVELOP ALONG THE HIGH TERRAIN OVER THE SRN NC MTNS AND THE HIGHER ELEVATIONS OF SC AND GA. CONVECTION SHOULD STRENGTHEN AS IT QUICKLY MOVES SOUTHEAST...WITH A FEW SEVERE STORMS A GOOD BET OVER THE SOUTHEAST PARTS OF THE CWFA BY MID TO LATE AFTERNOON. THERE SHOULD ALSO BE SEVERAL OUTFLOW BOUNDARIES RESULTING FROM THIS MORNING/S CONVECTION...AND STORMS THIS AFTERNOON MAY ALSO INITIATE AND TRACK ALONG THESE BOUNDARIES...THOUGH THE EXACT LOCATION OF THIS KIND OF MESOSCALE FORCING WON/T BE KNOWN UNTIL LATER IN THE DAY. WITH HIGH CLOUD BASES AND COOL MID LEVEL TEMPS...THERE SHOULD BE BOTH A HAIL AND WIND THREAT. TONIGHT AND SUNDAY THE GFS KEEPS AN AXIS OF INSTABILITY OVER THE SRN PART OF THE FORECAST AREA...ESPECIALLY THE SOUTHWEST MOUNTAINS. THE NAM AND WRF ARE A LITTLE DRIER WITH STRONGER NORTHWESTERLY FLOW ACROSS THE MOUNTAINS. WILL COMPROMISE AND KEEP LOW CHANCE POPS OVER THE SOUTHWEST. DUE TO ONGOING CONVECTION...DID NOT MAKE ANY CHANGES TO THE ZONES BEYOND SUNDAY. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... ANOTHER DAY...ANOTHER LOW CONFIDENCE MEDIUM RANGE FORECAST. GENERAL PATTERN REMAINS THE SAME...TROFINESS IN THE EAST AND RIDGE IN THE WEST. THIS CREATES NORTHWESTERLY FLOW ACROSS OUR AREA WITH DIFFICULT TO TIME SHORT WAVES MOVING THRU THE FLOW. THERE COULD BE A PATTERN CHANGE BY THE END OF THE PERIOD WITH THE TROF AND RIDGE MOVING EAST. AT THE SURFACE A STATIONARY FRONT REMAINS NEAR OR OVER THE AREA UNTIL THURSDAY WHEN IT MOVES BACK NORTH AS A WARM FRONT THEN EAST OF THE AREA THURSDAY. THAT SAID...EACH MODEL DIFFERS WITH THE POSITION AND TIMING OF THE FEATURES WITH EACH NEW RUN. THEREFORE...HAVE GONE VERY CLOSE TO HPC NATIONAL GUIDANCE. POP DISTRIBUTION GENERALLY SLIGHT CHC WEST/NOTHING EAST EARLY...THEN SLIGHT CHC MOST AREAS MIDDLE PERIOD...AND CHC WEST/SLIGHT CHC EAST BY THE END. TEMPS NEAR NORMAL EARLY RISING TO ABOVE NORMAL MIDDLE PERIODS AND REMAINING THRU THE END OF THE FORECAST. && .AVIATION... VSBY/CIG RESTRICTIONS DURING THE PRE-DAWN HOURS HIGHLY DEPENDENT ON TRACKS OF INDIVIDUAL DEEP CONVECTIVE CELLS AND BASED ON 88D DEPICTION...CERTAINLY KAVL STANDS THE BEST CHANCE OF THIS HAPPENING. BASED ON ORIENTATION OF COLDEST CLOUD TOPS AND THE EVOLUTION OF LLVL WAA MAX...HIGHEST CHANCES FOR DEEP CONVECTION THROUGH ABOUT 12 UTC WILL BE ACRS KAVL/KGSP AND THEN MOVING ON TOWARD KCLT. POTENTIAL TSTM CLUSTER SHOULD BE DOWNSTREAM OF KCLT BY A FEW HOURS AFTER SUNRISE WITH A DIURNAL LULL IN PCPN CHANCES. DEEP MIXED LAYER AGAIN THIS AFTERNOON...SO GUSTY WESTERLY WINDS EXPECTED FOR KGSP/KAND/KCLT. WRF DEPICTION OF AFTERNOON DEVELOPMENT AS GOOD AS A GUESS AS ANYTHING... SPREADING CONVECTIVE PCPN BACK INTO THE MTNS AND UPSTATE INTO EARLY EVENING. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE. SC...NONE. && SHORT TERM...MCAVOY LONG TERM...MCAVOY AVIATION...CSH
