What was reported inside it

Time	Report	Where	Remark

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this tornado 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 tornado warning went out at Oct 26, 8:00 PM EDT, 2 hours 33 minutes earlier.

Area forecast discussion, Oct 26, 8:00 PM EDT, 2 hours 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
800 PM EDT TUE OCT 26 2010

.SYNOPSIS...
AN ACTIVE COLD FRONT WILL MOVE INTO THE WESTERN CAROLINAS AND
NORTHEAST GEORGIA TONIGHT...THEN PUSH EAST OF THE FORECAST AREA BY
WEDNESDAY NIGHT. CANADIAN HIGH PRESSURE WILL THEN BUILD IN FOR THE
WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
TORNADO WATCH NOW IN EFFECT FOR ENTIRE FORECAST AREA BASED ON
MULTIPLE SUPERCELLS DEVELOPING AND MOVING THRU AN ENVIRONMENT RICH
WITH LOW LEVEL SHEAR AND SUFFICIENT BUOYANCY. SIGNIFICANT TORNADO
PARAMETER ON SPC MESO PAGE IS QUITE COMPELLING. LOOKS LIKE A BUSY
EVENING WITH TRAINING SUPERCELLS JUST E OF THE BLUE RIDGE. GRIDS AND
FORECAST WILL BE UPDATED PERIODICALLY TO ADJUST TEMP/DEWPT TRENDS
AND POP TRENDS.

REMAINDER OF PREVIOUS DISCUSSION...

LATE TONIGHT...DEEP LOW PRESSURE OVER MN WILL MOVE NORTH INTO
CANADA...RESULTING IN A DECREASE IN WIDESPREAD FORCING AND DEEP
SOUTHWEST FLOW. AS A RESULT...THE SFC FRONT MAY SLOW OR TEMPORARILY
STALL OVER THE FORECAST AREA TONIGHT. THE 12Z GFS INDICATES THE
FRONTOGENESIS WILL PIVOT OVER THE MTNS...STRONGEST OVER THE NRN
MTNS...AND GRADUALLY WEAKEN. ORGANIZATION AND STORM STRENGTH WILL
LIKELY DECREASE OVERNIGHT. HOWEVER...4 KM WRF INDICATES THAT A FEW
DISCRETE LINE SEGMENTS WILL EXIST EAST OF THE MTNS...SUPPORTED BY
STRONG LLVL SHEAR AND WEAK CAPE. I WILL INDICATE CATE POPS ACROSS
THE MTNS AND TIME LIKELY POPS ACROSS THE FOOTHILLS AND PIEDMONT. MIN
TEMPERATURE WILL REMAIN NEARLY 20 DEGREES ABOVE NORMAL...NEAR RECORD
HIGH MINIMUMS.

WEDNESDAY...TEMPERATURES WILL STEADILY WARM AFTER SUNRISE...PEAKING
IN THE U70S TO L80S EAST OF THE MTNS WITH DEWPOINTS MID TO U60S.
AFTERNOON CAPE VALUES SHOULD RANGE FROM 300-800 J/KG WITH HIGH SWEAT
AND HELICITY VALUES. STORMS WILL DEVELOP ALONG THE COLD FRONT AND
TRACK NE. BASED ON THE HIGH SHEAR LOW CAPE ENVIRONMENT...LINE
SEGMENTS OR STORM CLUSTERS MAY BECOME THE FAVORED STORM MODES. THE
PRIMARY THREAT WILL REMAIN WIND...WITH A BRIEF TOR POSSIBLE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 245 PM TUESDAY...THE SFC FRONT WILL CROSS THE REGION WED
NIGHT. THE NAM LLVL WINDS INCREASE INTO THE 50+ KT RANGE OVER THE
FOOTHILLS AND PIEDMONT AHEAD OF THE BNDRY. WITH THE INCREASING LLVL
CONVERGENCE...PCPN INCREASES ACROSS THE PIEDMONT BEFORE FINALLY
MOVING OUT OF THE FA SOMETIME AFTER MIDNIGHT. I/VE UPPED POPS INTO
THE HIGH CHANCE RANGE...BUT IF THE SLOWER AND MORE DYNAMIC TREND
CONTINUES...HIGHER POPS WILL BE IN ORDER WED EVENING. ATTN THE
INSTABILITY DOESN/T LOOK TO BE ALL THAT HIGH. BUT WITH DEWPOINTS
STILL WELL INTO THE 60S...THE BUFKIT SOUNDINGS ARE SHOWING A SMALL
AMOUNT OF CAPE. SO A MODEST SEVERE THREAT WILL CONTINUE INTO THE
EVENING HOURS...ESPECIALLY ACROSS THE WESTERN PIEDMONT. THE LLVL
FLOW QUICKLY VEERS TO THE WEST IN THE EARLY EVENING...WHICH SHOULD
CONFINE THE SEVERE THREAT TO A FEW SMALL AREAS OF STRAIGHT LINE WIND
DAMAGE.

THURSDAY WILL BE A MUCH DRIER DAY. DOWNSLOPE FLOW WILL WARM TEMPS
INTO THE M-U70S OVER THE FOOTHILLS AND PIEDMONT...WITH 60S IN THE
MTNS. THE GRADIENT TIGHTENS ACROSS THE THE MTNS THU NIGHT AS A
STRONG SHORT WAVE MOVES INTO THE MID ATLANTIC STATES. USING A BLEND
OF THE MET/MAV AND COOP MOS...I HAVE MIN TEMPS FALLING BELOW
FREEZING IN PART OF THE NC MTNS. FRIDAY WILL BE CLEAR AND
COOLER...THOUGH MAX TEMPS WILL STILL ONLY BE A DEGREE OR TWO BELOW
NORMAL.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 145 PM TUESDAY...THE EXT RANGE CONTINUES TO SHOW GOOD
CONTINUITY BTW MODEL RUNS AND OVERALL RUN TO RUN CONSISTENCY. THE
LARGE WAVE PATTERN IS WELL AGREED UPON UNTIL THE END OF THE PERIOD
WHEN SIGNIFICANT DYNAMIC DIFFERENCES ARISE. IN THE MEANTIME...EXPECT
THE CP SFC HIGH TO SLOWLY TRANSITION EAST ACROSS THE CWFA AND BY MON
THE CENTER SHOULD BE OFFSHORE ALLOWING SOME MEASURE OF GOM MOISTURE
ADV INTO THE AREA. THE 12Z GFS PUSHES A BACKDOOR COLD FRONT INTO THE
NRN ZONES SUN NIGHT...HOWEVER THIS FEATURE IS NOT SUPPORTED BY THE
00Z ECMWF AND LOOKS TO BE VERY DRY IN ANY REGARD. WITH UNCERTAINTY
IN THE LARGE SCALE SYNOPTIC PATTERN MON...WILL NOT JUMP ON THE
MOISTER GFS SOLN ATTM AND WILL GO WITH ONLY A SMALL AREA OF SLT
CHC UPSLOPE SHOWERS ACROSS THE SW MTNS...WITH POPS BECOMING MORE
WIDESPREAD TUE THEN GOING TO CHC ACROSS THE WRN ZONES AS MOISTURE
LEVELS WILL INCREASE. LITTLE IN THE WAY OF INSTABILITY SHOULD BE
REALIZED TUE WITH THE MIXED POLAR AIRMASS SLOW TO MODIFY...EVEN
CONSIDERING THE MORE DYNAMIC AND WARM ADVECTIVE GFS...SO TSTM
MENTION HAS BEEN LEFT OUT OF THE FCST. MAX TEMPS WILL START OUT
AROUND NORMAL SAT AND GRADUALLY BECOME A FEW DEGREES ABOVE NORMAL
THROUGH THE PERIOD. MINS WILL FOLLOW THE SAME TREND WITH MOISTURE
INCREASING THROUGH THE COLUMN.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...LOW LEVELS OF THE ATMOSPHERE RICH WITH SHEAR AND
INSTABILITY...BUT THE CONVERGENCE OF STORMS JUST EAST OF THE BLUE
RIDGE APPEARS TO REMAIN WEST OF KCLT UNTIL AFTER THE EVENING
PUSH...PROBABLY MOVING THROUGH SOME TIME IN THE EARLY MORNING HOURS.
UNTIL THEN...ONLY SCT LOW CLOUDS ARE EXPECTED WITH PERHAPS A BRIEF
LOW CLOUD CEILING. AS THE PRECIP BAND MIGRATES EASTWARD...A LOW
CLOUD CEILING SHOULD MOVE IN...AFTER 07Z...BECOMING MVFR AFTER 09Z.
THE FRONT ITSELF WILL NOT MOVE MUCH OVERNIGHT...SO WE WILL KEEP A
SHOWER AND THUNDERSTORM THREAT FOR THE TIME BEING. BOTH THE
SOUNDINGS AND MOS GUIDANCE SUPPORTS A MENTION OF MVFR CEILINGS...
AROUND 1500 FT...DEVELOPING DURING THE PRE DAWN HOURS ALONG WITH DZ
OR RA. MVFR CEILINGS SHOULD LIFT AFTER SUNRISE...WITH GUSTS AROUND
20 KTS REDEVELOPING BY 15Z. AFTER THAT...WE MAY BE IN AND OUT OF A
CONVECTIVE HIGH END MVFR CEILING THROUGH THE MIDDLE PART OF THE DAY
DEPENDING ON SHOWER DEVELOPMENT AND COVERAGE.

ELSEWHERE...THE EASTERN EDGE OF THE CONVECTIVE AREA WILL PERSIST
WHICH WILL BRING SEVERAL CELLS NEAR OR ACROSS THE OTHER TAF SITES.
FOR THE MOST PART...VFR CONDITIONS PREVAIL OUTSIDE THE
THUNDERSTORMS...SO ALL TAFS WITH EXCEPTION OF KAVL FEATURE THAT
ALONG WITH A VICINITY SHOWER/THUNDERSTORM. WILL AMEND TAFS AS STORMS
LOOK LIKE THEY WILL IMPACT THE TAF SITES.BOTH THE SOUNDINGS AND MOS
GUIDANCE SUPPORTS A MENTION OF MVFR TO IFR CEILINGS DEVELOPING
DURING THE PRE DAWN HOURS ALONG WITH DZ OR RA. LOW CEILINGS SHOULD
LIFT AFTER SUNRISE...WITH GUSTS AROUND 20 KTS REDEVELOPING BY 15Z.

OUTLOOK...CONVECTION AND CEILINGS MAY LINGER INTO WEDNESDAY EVENING
EAST OF THE MTNS. DRY HIGH PRESSURE WILL BUILD OVER THE REGION ON
THURSDAY AND REMAIN THROUGH MUCH OF THE WEEKEND.
