Damaging Wind in North Carolina, June 25, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1107 AM EDT FRI JUN 25 2004

.UPDATE...
MAIN BAND OF PRECIP NOT MAKING MUCH PROGRESS TO THE EAST THIS
MORNING...AND MAY NOT UNTIL IT STARTS TO FEEL THE EASTWARD PUSH OF
THE VORT CENTER SEEN ON WATER VAPOR IMAGERY OVER MS/AL/WRN TN. THIS
WILL HAVE MULTIPLE EFFECTS ON THE AFTERNOON WEATHER. THE AREA EAST
OF INTERSTATE 85...AND ESPECIALLY METRO CLT...WILL SEE A BIT MORE
SUN AND WILL PROBABLY WARM A BIT MORE THAN EXPECTED. TEMPS WILL BE
RAISED AS MUCH AS A CATEGORY...PARTICULARLY OVER WRN SC WHERE RAIN
COVERAGE HAD BEEN EXPECTED TO HOLD TEMPS DOWN. INSTABILITY SHOULD
NOT BE A PROBLEM OVER THE PIEDMONT...SO THINK THAT GRADIENT OF
CATEGORICAL/LIKELY POP STILL LOOKS REASONABLE BY THE END OF THE DAY.
EVEN THOUGH AXIS OF HEAVIER PRECIP WILL PROBABLY REMAIN W OF THE
MTNS FOR THE BETTER PART OF THE DAY...FLOOD WATCH WILL BE CONTINUED.
CONVECTIVE ELEMENTS ARE PERHAPS A BIT MORE LIKELY ACROSS THE NC
MOUNTAINS WHICH COULD LEAD TO A BETTER CHANCE OF FLASH FLOOD
PRODUCING RAINFALL RATES.

&&
.PREV DISCUSSION...
ISSUED AT 405 AM.
SHORT TERM...
COLD FRONT WILL BECOME STATIONARY NORTH OF THE FA TODAY AS FRONTAL
WAVE APPROACHES FROM THE SW. REGIONAL RADAR ALREADY SHOWS THE
COMMA-HEAD PRECIP TRACKING NE THIS MORNING. ETA AND GFS BRING THE
HEAD OVER THE HIGHER TERRAIN FROM 15Z-00Z...WITH GOOD UPSLOPE TAKING
PLACE FROM 15-21Z. HPC HIGHLIGHTS THE AREA WITH AN ISOLD EXCESSIVE
RAINFALL...WITH WIDESPREAD QPF >1. PWS APPROACH 2 THIS AFTERNOON
AND WILL EXPECT SHOWERS AND THUNDERSTORM TO MAKE EFFICIENT USE OF
THE MOISTURE...SOME STORMS LIKELY PRODUCING AROUND 2/HR. SUCH A
RATE WILL EXCEED FFG...HAVE POSTED A FLOOD WATCH FOR THE MTNS AND
ADJACENT FOOTHILLS OF THE CAROLINAS AND NE GA UNTIL MIDNIGHT. IF THE
ETA IS CORRECT PERIOD OF HEAVY RAIN WOULD LINGER OVER THE REGION
UNTIL 6Z...WILL LET DAYSHIFT DECIDE IF AFTER MIDNIGHT FOR THE WATCH
IS WARRANTED.

IN ADDITION TO THE RAINFALL...SVR TS MAY ALSO BE ON THE DOCKET FOR
TODAY. REASONABLE T/TD ON THE MESOETA FORECAST SOUNDINGS YIELD CAPES
>2K J/KG WITH WINDS 30KT AT H85 AND HIGHER. HOWEVER...HIGH FZ
LEVELS AND MOIST AIR WILL LIMIT HAIL PRODUCTION. PRIMARY SVR THREAT
WILL BE THE POTENTIAL FOR STRONG DOWNBURSTS. SPC SHOWS THE ENTIRE FA
IN A SLGT RISK TODAY...WILL ISSUE A SPS TO HIGHLIGHT.

ETA AND GFS DIFFER FOR THE WEEKEND IF THE FRONT WILL BE ABLE TO PUSH
SOUTH OF THE REGION. ALTHOUGH THE GFS IS PREFERRED WILL ADOPT A
COMPROMISE AND WILL FORECAST THE FRONTAL POSITION TO REMAIN
IN BETWEEN THE TWO SOLUTIONS. THIS WILL RESULT IN KEEPING A CHC FOR
SH/TS INTO THE EARLY WEEK...BECOMING MORE DIURNAL. OMEGA BLOCK TO
THE WEST WILL BE SLOW TO UNRAVEL...HOWEVER MEDIUM RANGE MODELS BRING
A RETURN OF MOISTURE FOR THE EARLY WEEK PERIOD...WILL MODIFY CURRENT
FORECAST.

LONG TERM...

LITTLE CHANGE BEYOND MONDAY.
