Area forecast discussion, Jul 28, 2:44 PM EDT, 4 hours 46 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
244 PM EDT THU JUL 28 2005

.SHORT TERM (TONIGHT THROUGH FRIDAY)...
88D TRENDS THROUGH THE REST OF THE AFTERNOON SHOULD DEPICT
BLOSSOMING CVRG OF DEEP CONVECTION THANKS TO THE COMBINATION OF
DEEPER RH PRESSING IN FROM THE NORTHWEST...A MODERATELY TO VERY
UNSTABLE AIRMASS AND LLVL CONVERGENCE AXIS BISECTING THE CWFA.
WILL CONTINUE TO FCST NUMEROUS TSTM CVRG THROUGH MIDNIGHT.
FOR THE OVERNIGHT HOURS...SHORT RANGE MODELS HAVING TROUBLE
RESOLVING THE DETAILS OF SPECIFIC AREAS OF LIFT...BUT BOTH
THE NAM AND THE GFS HAVE PCPN RESPONSE LINGERING ACRS NC...
SO WILL HANG ONTO LIKELY CVRG THERE AND DROP POP TO SCATTERED
EVERYWHERE ELSE.

ON FRIDAY...CONTINUED UNSETTLED WEATHER LOOKS PROBABLE AS UPPER
TROUGH AXIS DIGS JUST UPSTREAM OF THE CWFA WITH A PRETTY STOUT
AREA OF LARGE SCALE ASCENT AHEAD OF THE TROUGH AXIS. AGAIN...
MODELS LINGER DEEP RH WITHIN THE CWFA AND DECENT AGREEMENT
AMONG NUMERICAL GUIDANCE POP ADVERTISING ANOTHER AFTERNOON/EVENING
WITH NUMEROUS TSTMS.

&&

.LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)...
THE UPPER TROUGH AXIS WILL SLOWLY DRIFT TO THE EAST COAST DURING THE
WEEKEND AS THE SURFACE FRONT LINGERS AND GRADUALLY FADES OVER OR
NEAR THE COASTAL PLAIN DURING THE NEXT SEVERAL DAYS.  HIGH
PRECIPITABLE WATER VALUES OF OVER TWO INCHES WILL COEXIST WITH THE
FRONT AT LEAST THROUGH THE FIRST HALF OF THE WEEKEND.  A GOOD AREA
OF OMEGA WILL MOVE NORTHEAST NEAR INTERSTATE 85 FRIDAY NIGHT.  AFTER
THAT...NUMEROUS SHOWERS AND THUNDERSTORMS WILL BE MAINLY CONFINED TO
LOCATIONS SOUTHEAST OF INTERSTATE 85. A FEW INCHES OF RAIN COULD
FALL IN PARTS OF THE CAROLINAS AND GEORGIA DURING THE NEXT FEW DAYS.

IF THE FRONT REMAINS CLOSER TO THE COAST AS EXPECTED AND SLOWLY
DISSIPATE...OUR CHANCES OF RAIN WILL DIMINISH GOING INTO THE
UPCOMING WEEK.  WITH A COOLER AIRMASS AND LOTS OF CLOUDINESS...NO
MORE NEAR RECORD TEMPERATURES FOR A WHILE.  HIGH TEMPERATURES WILL
BE BACK TO NEAR NORMAL BY MID NEXT WEEK.

WE WILL THEN BE WATCHING THE PROGRESS OF THE NEXT TROPICAL SYSTEM
WHICH IS PROJECTED TO APPROACH THE BAHAMAS IN MID WEEK THEN PERHAPS
MOVE WEST WITH HIGH PRESSURE BLOCKING IT FROM GOING NORTH.

&&

.AVIATION...
THE COMBINATION OF DEEPER RH PRESSING IN FROM THE NORTHWEST...A
MODERATELY TO VERY UNSTABLE AIRMASS AND LLVL CONVERGENCE AXIS
BISECTING THE CWFA COINCIDENT WITH SYNOPTIC SCALE FRONT...SHOULD
CONTINUE TO PROMOTE DEEP CONVECTIVE CVRG BECOMING NUMEROUS AND
WILL CARRY AT LEAST TWO TEMPO PERIODS AT ALL TAF LOCATIONS TO
COVER HIGH TSTM PROBABILITIES YET REFLECT TIMING UNCERTAINTY.
AS THE NIGHT WEARS ON...SHORT RANGE MODELS PROGGING BETTER
WAA LIFT NORTH OF FRONT AND WILL HANG ONTO SHOWER CHANCES
FURTHER INTO THE OVERNIGHT FOR MY NC TAFS. AT THIS POINT...
DOES NOT LOOK LIKE ANYTHING WORSE THAT MVFR RESTRICTIONS
DURING THE PRE-DAWN HOURS.
