AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 250 PM EDT SUN JUL 11 2004 .SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)... NUMEROUS SHOWERS AND THUNDERSTORMS ARE DEVELOPING ALONG THE LEE SLOPES ATTM. COMBINATION OF 10 KT ELY UPSLOPE FLOW (AS SEEN ON THE KGSP-88D VAD WIND PROFILER) AND VERY HIGH DWPT AIR (L70S) IS RESULTING IN THE PCPN. WE REALLY ARE NOT ALL THAT FAVORABLE ALOFT WITH WEAK ANITCYCLONIC FLOW...BUT LLVL FORCING IS OVERCOMING THAT. SO FAR PCPN HAS NOT ANCHORED VERY LONG IN ONE PLACE. INSTEAD IT SEEMS TO MOVE ONTO NEW...UNDISTURBED AIR RATHER THAN STANDING IN ONE PLACE. THIS PROBABLY HAS SOMETHING TO DO WITH THE WEAK DEEP LAYER SHEAR...BUT STILL WOULD NOT BE SURPRISED TO SEE A FEW FLOODING PROBLEMS DEVELOP. WE HAVE AN SPS ADDRESSING THIS ISSUE. ALL THE NUMERICAL MODELS PROG THE LLVL FLOW TO VEER RATHER MARKEDLY EARLY THIS EVENING...SO I THINK WE WL SEE THE PCPN BEGIN TO MOVE A LITTLE MORE TO THE EAST AND AFFECT SLOPES WITH A DIFFERENT ASPECT. THEREFORE WL NOT ISSUE A FLOOD WATCH ATTM. LATER TNGT BOTH THE ETA AND GFS BRING A WEAK H5 SHORTWAVE INTO THE MTN ZONES. THE MID SHIFT CAUGHT ON TO THIS AND HAVE CONTINUED CHANCE POPS ALL NGHT IN THE WRN MTNS. MON AND TUE LOOK QUITE SIMILAR WITH WEAK CYCLONIC FLOW OVER THE REGION AS HGHTS BEGIN TO FALL OVER THE ERN CONUS. LAYER RH VALUES ARE HIGHER ON MON...SO SUSPECT COVERAGE WL BE GREATER. SPC EVEN HAS US IN A SEE TEXT AREA...SUSPECTING THAT SOME WET MICROBURSTS MIGHT BE POSSIBLE LATER TMRW. LATE MON NGHT WE ONCE AGAIN SEE SHORT WAVE ENERGY ENTER THE WRN ZONES..AND HAVE AGAIN KEPT ELEVATED POPS IN THE WRN ZONES. WITH A DRIER COLUMN ON TUE...HAVE LOWERED POPS TO 30 PERCENT ACROSS THE CWA. SEVERE THREAT MAY BE LITTLE HIGHER WITH EVEN DRIER AIR ALOFT...THOUGH IT WL BE LOCALIZED WITH LGT SHEAR. ON WED AN UNSEASONABLY STRONG LONG WAVE TROF RAPIDLY BEGINS TO DEEPEN OVER THE ERN CONUS. THIS WL SEND A RATHER STRONG COLD FRONT THROUGH THE REGION WED NGHT. MODELS SHOW GOOD INSTABILITY AHEAD OF THE FRONT...BROAD H5 PVA AND BETTER SHEAR THAN WE HAVE HAD FOR A WHILE. THE BEST LLVL CONVERGENCE STAYS WELL E OF THE REGION...BUT CERTAINLY CANNOT RULE OUT CHANCE POPS ATTM WED AFTN. && .LONG TERM (THURSDAY THROUGH SUNDAY)... WE WL BE ON THE BACK SIDE OF THE STRONG LONG WAVE TROF THU-SAT WHICH WILL RESULT IN COOLER TEMPS AND LOWER DWPTS. AFTER THE RECENT MUGGY AND HOT WEATHER...IT WL FEEL VERY NICE. SOME TEMPERATURE AND DWPT RECOVERY ON SUN AS FLOW BECOMES MORE ZONAL...BUT WL STILL KEEP THE FORECAST DRY. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE.

EASTERLY LOW LEVEL WINDS WILL LIFT VERY MOIST AIR ACROSS THE FOOTHILLS AND INTO THE EASTERN SLOPES OF THE MOUNTAINS THIS AFTERNOON AND EVENING. THIS WILL RESULT IN SLOW MOVING THUNDERSTORMS CAPABLE OF PRODUCING VERY HEAVY RAIN. A FEW AREAS WILL LIKELY SEE SEVERAL INCHES OF RAIN...WITH ISOLATED FLASH FLOODING DEVELOPING. IF IT APPEARS THAT THE HEAVY RAIN WILL BECOME MORE WIDESPREAD...AND WITH IT THE FLASH FLOOD THREAT....THEN A FLOOD WATCH MAY NEED TO BE ISSUED LATER IN THE AFTERNOON. SOME OF THE THUNDERSTORMS WILL ALSO BE CAPABLE OF PRODUCING DAMAGING WINDS AS THEY BRING DOWN DRIER AIR IN THE MIDDLE LEVELS OF THE ATMOSPHERE. THERE MAY BE SOME LARGE HAIL...BUT THE PRIMARY SEVERE WEATHER CONCERN WITH THESE STORMS WILL BE DAMAGING WINDS IN EXCESS OF 60 MPH. AREAS WITH THE BEST CHANCE OF SEEING HEAVY RAIN AND SEVERE THUNDERSTORMS WILL BE ALONG AND WEST OF A LINE FROM WALHALLA TO GREENVILLE...RUTHERFORDTON...MORGANTON AND LENOIR. SPOTTER GROUPS SHOULD BE PREPARED TO ACTIVATE QUICKLY LATE THIS AFTERNOON AND THIS EVENING. DISPATCHERS SHOULD ENSURE COUNTY EMERGENCY MANAGEMENT OFFICIALS ARE AWARE OF THIS INFORMATION.
