What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Aug 7, 7:26 PM EDT, 32 minutes earlier.

Area forecast discussion, Aug 7, 7:26 PM EDT, 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
726 PM EDT SUN AUG 7 2011

.SYNOPSIS...
A WEAK FRONT WILL STALL OVER THE MOUNTAINS ON MONDAY AND REMAIN
THERE THROUGH TUESDAY. THE FRONT WILL PUSH SOUTH OF OUR AREA ON
WEDNESDAY AS HIGH PRESSURE BUILDS IN FROM THE NORTH. ANOTHER COLD
FRONT WILL APPROACH THE AREA OVER THE WEEKEND.

&&

.NEAR TERM /THROUGH MONDAY/...
TWEAKED SKY COVER AND POPS TO REFLECT LATEST TRENDS WITH CONVECTION.
NEW PRODUCTS ARE COMING OUT NOW.

PREVIOUS DISCUSSION...A WEAKENING MCV/VORTMAX CAN BE SEEN ON
SATELLITE IMAGERY OVER ERN TN WITHIN STRENGTHENING WESTERLY FLOW.
THE VORT WILL TRACK THRU THE CWFA THIS EVENING...AND SHUD HELP KICK
OFF CONVECTION LATE THIS AFTN AND EVENING. THE ENVIRONMENT IS VERY
MOIST AND UNSTABLE...WITH A LTL GREATER CAPE AND SHEAR THAN
YESTERDAY. THE GSP VWP SHOWS WEAK WESTERLY LLVL FLOW...WITH NWLY
FLOW AT 6000 FT AND HIGHER. SO HAVE NOT REALLY STARTED MIXING OUT
YET...AND DCAPES ARE STILL RELATIVELY LOW...BUT STILL EXPECTED TO
INCREASE. SO SEVERE THREAT DOES NOT LOOK MUCH HIGHER THAN YESTERDAY
AT THE MOMENT. PWATS STILL RUNNING 150+ PERCENT OF NORMAL. SO
EXCESSIVE/HEAVY RAIN IS STILL A THREAT WITH ANY CONVECTION THAT DOES
DEVELOP.

TONIGHT...DRIER MID LVL AIR WILL PUSH IN BEHIND THE WEAK
VORTMAX...AS WESTERLY 700 MB FLOW STRENGTHENS TO 25-35 KTS. SKIES
SHOULD CLEAR OUT SAVE FOR SOME LINGER CIRRUS...AND POPS QUICKLY
TAPER TO BELOW 15 PERCENT. LOWS WILL BE IN THE 60S MTNS AND LWR-MID
70S PIEDMONT.

MONDAY...FOR THE BULK OF THE DAY THE CWFA WILL BE WITHIN RELATIVELY
DRIER WESTERLY FLOW...WITH A RIPPLE OF SHORTWAVE RIDGING ALOFT AND
LLVL DOWNSLOPE. SO A LATER START TO CONVECTION WITH COVERAGE
GENERALLY WIDELY SCATTERED MTNS AND ISOLATED PIEDMONT. STEEPER LLVL
LAPSE RATES AND DRY MID LVLS WILL LIKELY RESULT IN A HIGHER
PERCENTAGE OF STORMS TO PRODUCE DOWNBURSTS. BUT NOT EXPECTING
ANYTHING ORGANIZED. TEMPS WILL BE QUITE WARM WITH MORE INSOLATION
AND DOWNSLOPE (80S TO LWR 90S MTN VLYS AND GENERALLY UPR 90S TO 100
PIEDMONT).

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
AS OF 215 PM SUNDAY...AN UPPER LEVEL SHORTWAVE ROUNDING A VIGOROUS
SRN CANADIAN TROUGH WILL INTERACT WITH A COLD FRONT IN PLACE ACROSS
THE LOWER OH VALLEY MON NIGHT TO LIKELY TRIGGER CONVECTION THERE.
THE RESULTING MCS SHOULD MAKE A RUN TOWARD THE SRN APPALACHIANS
DURING THE EARLY MORNING HOURS TUE. THERE REMAINS CONSIDERABLE
QUESTION ABOUT WHETHER THE MCS WILL REACH OUR FORECAST ACTIVITY WITH
ANY PUNCH EARLY TUE...AND HOW FAR EAST IT WILL PENETRATE. THE WEAK
INSTABILITY SHOULD LEAD TO A DECAYING SYSTEM REACHING THE NC
MTNS...AND PROBABLY DISSIPATING E OF THE MTN CHAIN TUE MORNING. THE
POP GRIDS WILL REFLECT THIS APPROACH. IN ADDITION...ANOTHER MCS
COULD DEVELOP LATER IN THE DAY ALONG THE TRAILING BOUNDARY IN THE
MID MS VALLEY...AND ALSO MAKE AN EASTWARD RUN THROUGH TUE EVENING.
OTHERWISE...W TO NW DOWNSLOPE FLOW WILL BOOST WARMING E OF THE MTNS.
EARLY DEBRIS CLOUDS AND SLIGHTLY MIXED DEWPOINTS SHOULD KEEP MOST OF
THE AREA BELOW ANY ADVISORY CRITERIA...BUT HEAT INDEX VALUES ABOVE
100 ARE LIKELY IN THE SRN PIEDMONT TUE AFTN.

THE WEAK COLD FRONT UPSTREAM WILL PUSH SE TOWARD THE AREA LATER
TUESDAY NIGHT INTO WED. SOME THICKNESS FALLS ARE INDICATED ACROSS
THE AREA WED AFTN...BUT PERSISTING WEST TO NW DOWNSLOPE FLOW E OF
THE MTNS WILL STILL KEEP TEMPS ABOVE NORMAL. MUCH DRIER AIR SHOULD
ARRIVE IN PROFILES WED...WITH ANY SLIGHT CHANCES FOR CONVECTION
CONFINED MAINLY TO CENTRAL AND NRN MTN LOCATIONS IN THE NW FLOW.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AS OF 225 PM SUNDAY...THERE IS GOOD OVERALL AGREEMENT IN THE OP
MODELS AND LITTLE SPREAD SEEN IN THE GFS ENS THROUGH THE EXT RANGE.
THERE ARE SIGNIFICANT DIFFERENCES IN THE SMALLER SCALE AND EVEN THE
TREATMENT/MAGNITUDE OF THE LLVL AIRMASS...BUT THE GENERAL FLOW AND
SYNOPTIC DYNAMICS ALLOW ABOVE AVERAGE CONFIDENCE THROUGH SAT...AND
NORMAL TO BELOW CONFIDENCE AFTER THAT THROUGH MON.

UPPER LEVEL HEIGHTS REMAIN BROAD AND WEAKLY CYCLONIC WITH SMALL
POCKETS OF S/W ENERGY CROSSING THE CWFA THU THROUGH FRI...HOWEVER
MOISTURE WILL BE LOW AS A SFC HIGH BUILDS EAST ACROSS THE OH VALLEY.
A GOOD DEGREE OF INSOLATION AND WEAK AIRMASS MIXING WILL ALLOW TEMPS
TO REACH A FEW DEGREES ABOVE NORMAL...BUT SFC TD/S WILL STILL MIX
OUT INTO THE LOWER TO MID 60S MAKING FOR A RATHER PLEASANT
CONDITIONS BOTH DAYS.

THE MODELS BEGIN TO DIVERGE WITH THE FRONTAL SYSTEM SAT THROUGH THE
PERIOD. BETTER AGREEMENT IS HAD BETWEEN THE CMC AND THE GFS...SO THE
FORECAST WAS CRAFTED WITH A MIX OF THESE IDEAS IN MIND. THERE SHOULD
BE INCREASING MOISTURE FLUX AHEAD OF THE COLD FRONT SAT AND THIS
WILL ENABLE SHOWER ACTIVITY...WITH DEEPER CONVECTION DRIVEN BY
AFTERNOON DESTABILIZATION. DONT ANTICIPATE MUCH IN THE WAY OF A
SEVERE THREAT AS SBCAPE REMAINS SHALLOW AND WEAK WHILE SHEAR DOESNT
INCREASE ABOVE 15 KTS UNTIL H5. THERE WILL BE LINGERING ACTIVITY SUN
AS FROPA LOOKS TO BE BTW 12Z-15Z. THE OVERALL DYNAMICAL SHEAR
INCREASES WITH THE FRONT...BUT AGAIN CAPE WILL BE ON THE LOW END SO
DONT ENVISION MUCH IN THE WAY OF A SEVERE THREAT.

MAX TEMPS SAT AND SUN WILL STILL BE A COUPLE DEGREES ABOVE NORMAL OR
RIGHT AROUND NORMAL...WITH HIGHER TD/S SAT MAKING FOR MORE HUMID
CONDITIONS. THERE WILL BE A DECENT AIRMASS MIX SUN POST FROPA...SO
PLEASANT CONDITIONS WILL BE IN STORE FOR SUN AFTERNOON INTO NEW DAY
7.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
AT KCLT AND ELSEWHERE...CB WILL BE CARRIED ALL TERMINALS UNTIL 01Z
WHEN COOLING SHOULD WEAKEN CONVECTION. CLEARING OVERNIGHT WITH MVFR
FOG KAVL. EXPECT W-NW WINDS KCLT...W ELSEWHERE EXCEPT NW KAVL.
INCLUDED CB CLOUDS AFTER 17-18Z MON AS ISOLD TSTMS RETURN WITH
HEATING...SCT TSTMS MTNS.

OUTLOOK...MOISTURE WILL GRADUALLY DIMINISH EARLY NEXT WEEK IN
PERSISTENT WESTERLY FLOW. STILL EXPECT ISOLD-SCT SHWRS/TSTMS THRU
THE PERIOD.
