What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this flash flood warning went out at Jul 13, 3:31 PM EDT, 1 hour 13 minutes earlier.

Area forecast discussion, Jul 13, 3:31 PM EDT, 1 hour 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
331 PM EDT SUN JUL 13 2003

FOR THE SHORT TERM...MULTICELLULAR CLUSTERS OF THUNDERSTORMS WILL
CONTINUE TO DEVELOP AND MOVE EAST ACROSS THE WESTERN CAROLINAS WELL
INTO THE EVENING HOURS. EXPECT A FEW MORE SEVERE THUNDERSTORMS GIVEN
A FAVORABLE ENVIRONMENT OF COOL TROF AT MID LEVELS AND LOW LEVEL
CONVERGENCE ALONG AND SOUTH OF SURFACE BOUNDARY CUTTING EAST TO WEST
ACROSS THE FORECAST AREA. THE CONVECTION MAY PERSIST THROUGH THE
OVERNIGHT HOURS AS IT SHIFTS OFF TO THE EAST AS THE SYNOPTIC
ENVIRONMENT SHOULD CONTINUE TO SUPPORT IT...WITH SHORT WAVE ROTATING
AROUND BOTTOM OF UPPER TROF AND UPPER DIVERGENCE IN RIGHT ENTRANCE
REGION OF UPPER JET.

ON MONDAY...THE BEST FORCING SHIFTS OFF TO THE EAST...PUTTING THE
PIEDMONT IN THE GRADIENT OF PRECIP PROBABILITY WITH CHANCE ACROSS
THE MOUNTAINS AND FOOTHILLS AND LIKELY TO OUR EAST. THE FORCING
SHOULD DIMINISH LATE IN THE DAY AS ENERGY PULLS OUT OF THE UPPER
TROF. AS A RESULT...CONVECTION SHOULD ALSO BE MORE DIURNAL IN
NATURE. TUESDAY AND WEDNESDAY SHOULD ALSO FEATURE TYPICAL DIURNAL
CONVECTION. HAVE STAYED RELATIVELY CLOSE TO TEMP GUIDANCE
THROUGHOUT.

FOR THE MEDIUM RANGE...HAVE FOLLOWED HPC SCENARIO AND GUIDANCE
FAIRLY CLOSELY...WHICH FAVORS THE ENSEMBLE GFS/ECMWF. THIS SCENARIO
KEEPS PRECIP PROBABILITY AND TEMPS CLOSE TO CLIMATOLOGY. SEE LITTLE
REASON TO CHANGE MUCH OF WHAT WE HAVE IN THE ONGOING FORECAST...WITH
THE EXCEPTION OF HIGH TEMPS ON SATURDAY...WHICH WILL BE RAISED A FEW
DEGREES TO COME INTO LINE WITH ENSEMBLE MOS GUIDANCE UNDER THE
ASSUMPTION THAT ANY FRONT THAT MIGHT MOVE THROUGH WILL BE WEAK.
