AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 904 PM EDT MON APR 12 2004 .UPDATE... ORIENTATION AND STRENGTH OF WEDGE HAS CHANGED LITTLE SINCE MID-AFTERNOON WITH KGSP VWP STILL INDICATING A NE WIND IN THE LOWEST GATE. 18Z ETA AND GFS BOTH TOO LOW WITH PROGGED PRESSURE FALLS AT 00Z AND THE ETA IN FACT WAS WAY TOO AGGRESSIVE WITH SFC BASED INSTABILITY WHICH WAS PROGGED TO BE WEST OF CLT BY NOW. 18Z GFS WAS ACTUALLY CLOSER TO REALITY AS PER 00Z MSAS LI PLOT. LIFTING PARCELS FROM ABOVE SFC LAYER DOES YIELD SOME POSITIVE CAPE AND NEGATIVE SHOWALTER INDEX VALUES AND THIS IS APPARENT WITH CURRENT 88D SHOWING TSTM NEAR NE GA. FEEL 18Z GFS HANDLING OF SHOWALTER INDEX FIELD PRETTY GOOD INTO THE OVERNIGHT AND WILL HAVE THUNDER MENTION...WHETHER IT REMAINS ELEVATED OR NOT...ABOUT HALF WAY NORTH INTO THE NC MTNS AND EXTENDING FURTHER WEST...PAST I-77 IN THE PIEDMONT. PROBABLY WILL SEE LITTLE CHANGE IN WEDGE ORIENTATION THIS EVENING...BUT INCREASING DEEP FORCING OUT AHEAD OF APRCHG VORT SHOULD BE ABLE BEGIN PINCHING WEDGE OFF OVERNIGHT. TO WHAT DEGREE WEDGE EROSION OCCURS BY DAYBREAK IS QUITE DEBATABLE...BUT WILL GO SLOWER THAT WHAT 18Z ETA IS OFFERING. AS FAR AS PCPN CVRG FOR THE OVERNIGHT...THE LARGE SCALE PATTERN WOULD DEFINITELY FAVOR AN INCREASE IN SHOWERS AND SOME THUNDER...AND POP GRIDS WILL TREND TO THIS DIRECTION INTO TUESDAY MORNING. WILL CONTINUE WILL CATEGORICAL CVRG IN THE WEST AS QPF MAX SLIDES NWD INTO THIS AREA. LITTLE CHANGE TO CURRENT SPC DAY 1 SLIGHT RISK WITH LATEST UPDATE AND PLAN ON REFRESHING CURRENT SPS TO ADDRESS POSSIBLE SVR THREAT FOR THE OVERNIGHT HOURS. && .PREV DISCUSSION... THE WEDGE REMAINS IN PLACE OVER THE CWA WITH WARM FRONT TO THE SOUTH RUNNING FROM ILM TO AGS. OVERRUNNING PRECIP REMAINS THE FORECAST ISSUE TODAY. THE PROBLEM IS THAT TEMPERATURES ARE PARTICULARLY UNSTABLE ALOFT AND AS THE FRONT DRIFTS NORTHWARD...WE MOVE INTO A REGIME THAT COULD PRODUCE SEVERE THUNDERSTORMS SOUTH OF I85. TEMPERATURES REMAIN IN THE 40S TO LOW 50S IN OUR AREA BUT 60S AND 70S FROM CAE SOUTHWARD. WITH SFC DWPNTS IN THE 60S AND 70S IN SOUTH OF FRONT WILL PROVIDE AMPLE MOISTURE FOR TSTMS DVLPMNT. SPC KEEPS US IN THEIR OUTLOOK THROUGH TUESDAY. MIN TEMPERATURES WILL BE SOMEWHAT CONFUSING AS I EXPECT SLOW WARMING THROUGH THE NIGHT. SOME CONCERN ABOUT HOW FAST TO SCOUR OUT THE WEDGE. WE NORMALLY HAVE A TENDENCY TO WARM THINGS UP TO QUICKLY. BUT IT IS LATE ENOUGH IN THE YEAR...AND THE COLD AIR IS SHALLOW ENOUGH TO EXPECT THINGS TO WARM UP STARTING TUESDAY. ETA REMAINS MODEL OF CHOICE IN THE SHORT TERM. WRAPAROUND FLOW BEHIND LOW IS EXPECTED TO CAUSE PROBLEMS IN THE MOUNTAINS LATE TUESDAY AND WEDNESDAY. FCST SOUNDINGS INDICATED RAIN AND SNOW MIX...ENDING WITH JUST SNOW WEDNESDAY MORNING. SOUNDINGS INDICATE SNOW DOWN TO 3300 FEET BEFORE ENDING. I DONT EXPECT MUCH OF AN ACCUMULATION EXCEPT ON HIGHEST TERRAIN. AFTER THAT THINGS CLEAR UP AND WE GET BACK INTO A SPRINGTIME REGIME AGAIN. NEXT SURGE NEXT MONDAY WITH GFS SOUNDINGS PRETTY IMPRESSIVE FOR THUNDERSTORMS MONDAY AFTERNOON THEN WITH APPROACHING FRONT. KEEPING POPS IN SILENT SLIGHT CHANCE RANGE UNTIL IT GETS CLOSER. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE. SC...NONE. && CSH
