Area forecast discussion, May 2, 1:50 PM EDT, 4 hours 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 150 PM EDT TUE MAY 2 2000 LOCATION OF SFC FRONT AGREES WELL WITH THE 12Z ETA. FRONT IS PROGGED TO DEVELOP ALONG BARRIER COMPONENT AND SLIDE JUST S AND W OF THE CWA BY WED MORNING. HIGH CONTINUES TO BUILD INTO THE REGION... PUSHING SFC CONVERGENCE WELL W OF THE AREA WED AFTN THROUGH THU. THIS RAISES SOME INTERESTING QUESTIONS AS THERE ARE RATHER LARGE MODEL DIFFERENCES IN THE QPF FIELDS. THE FIRST PERIOD LOOKS REASONABLE AS THE ETA GENERATES CONVECTIVE PCPN ALONG ZONE OF STRONG SFC CONVERGENCE AS THE BACK DOOR FRONT DROPS INTO THE NC PIEDMONT. THIS CONVECTION MOVES SE...ALONG THE SFC BNDRY...OVERNIGHT. WEAK H5 MINOR WAVE AND RETREATING H3 JET LEND SUPPORT FROM SOME KIND OF RELATIVELY WEAK MCS. LAPSE RATES ARE NOT VERY STEEP...THOUGH LVLV MOISTURE IS INCREASING. CAPES AVERAGING AROUND 1000 OVER MOST OF THE CWA ATTM. THUS...SOME CONVECTION IS POSSIBLE ALMOST ANYWHERE THIS EVENING. WL KEEP AN EYE ON TRENDS...BUT PLAN TO HAVE HIGHEST POPS ERN ZONES...AND LOWER POPS W. BY WED MOST OF THE BNDRY LAYER FLOW OVER THE CWA IS E TO ENE...AND RATHER BRISK IF THE ETA IS CORRECT. HARD TO IMAGINE MUCH CONVECTION WL DEVELOP WHERE THERE IS NO SFC CONVERGENCE AND PRACTICALLY NO FORCING ALOFT AS UPPER RIDGE ROLLS OVER THE AREA. THINK MOST CONVECTION WOULD DEVELOP ON SFC CONVERGENCE WELL W OF THE CWA. THE MTNS...HOWEVER...SHOULD SEE SOME TSRA DEVELOP W/DIFFERENTIAL HEATING AND AS THEY WL BE ABOVE THS COLD POOL. ETA HAS LLVL DWPTS POOL ALONG AND N OF THE BNDRY W/M60 DWPTS FEEDING ANYTHING THAT DOES GO IN THE HIGHER ELEVATIONS. WL UNDERCUT TEMPS AS WE WL HAVE NE FLOW AND A CLOUD DECK OVER THE COLD POOL. 12Z SFC TRAJECTORIES HAVE THE SOURCE REGION FOR THE AIRMASS NOT TOO FAR TO THE N...SO WL ONLY UNDERCUT RAFS BY 5 OR 6 DEG UNLESS OTHER OFFICES OBJECT. ETA DEVELOPS A HUGE AREA OF RAIN OVER THE SW CWA WED NGHT AND KEEPS IT THERE THROUGH THU. WE/D BE LOOKING AT 2 INCHES OF RAIN IF IT WAS RIGHT. THE AVN IS FURTHER SW AND THE UKMET SIMPLY HAS A LOT LESS PCPN. AGAIN...THINK MOST CONVECTION WL FORM ALONG SFC CONVERGENCE W OF CWA...WITH ONLY THE MTN ELEVATIONS REALLY SEEING ANY SIG PCPN. HARD TO COMPLETELY ARGUE AGAINST THE ETA HOWEVER...AND WL BUMP POPS UP TO GOOD CHANCE SW HALF OF CWA WED NGHT AND THU. STILL LOOKS WARM WITH AFTN AND EVENING TSRA IN THE EXTENDED.
