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.

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 Apr 4, 8:16 PM EDT, 52 minutes earlier.

Area forecast discussion, Apr 4, 8:16 PM EDT, 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
816 PM EDT FRI APR 4 2008

.SYNOPSIS...
A COLD FRONT WILL CROSS THE WESTERN CAROLINAS AND NORTHEAST GEORGIA
OVERNIGHT. THE FRONT WILL STALL OVER THE PIEDMONT SATURDAY...THEN
PUSH EAST OF THE AREA SATURDAY NIGHT. A WEAK AND RELATIVELY DRY
WEDGE OF HIGH PRESSURE WILL THEN MOVE OVER THE EASTERN UNITED STATES
SUNDAY...AND REMAIN LARGELY IN PLACE THROUGH THE MIDDLE OF NEXT
WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
TORNADO WATCH IS STILL IN EFFECT FOR NORTHEAST GA AND THE WESTERN
UPSTATE TILL 10 PM. ANOTHER TORNADO WATCH IS IN EFFECT FOR THE REST
OF THE UPSTATE AND THE SOUTHWESTERN NC PIEDMONT UNTIL 1 AM SATURDAY.
A LINE OF SHOWERS AND STORMS WILL CONTINUE TO TRACK EAST ACROSS THE
PIEDMONT THROUGH THE EVENING HOURS. UPSTREAM...ANOTHER LINE OF
SHOWERS AND TSTMS IS TRACKING INTO NE GA. COOLER AND MORE STABLE AIR
SHOULD PUSH IN BEHIND THE SECOND LINE...HELPING TO DECREASE CHCS OF
THUNDER FOR THE REST OF THE NIGHT.

AN UPPER TROUGH WILL CROSS THE MS RIVER VALLEY TONIGHT...AND THE
SOUTHERN APPALACHIANS ON SATURDAY. COLD AIR DAMMING OVER THE AREA IS
ERODING...BUT SOME AREAS ALONG THE BLUE RIDGE MAY BE SLOW TO SEE
THE WARM SECTOR AIR ARRIVE. UPGLIDE CONTINUES TO DECREASE...BUT AS A
COLD FRONT APPROACHES FROM THE WEST...INSTABILITY AND OMEGA WILL
INCREASE...SUPPORTING INCREASING PRECIPITATION COVERAGE AND AMOUNTS.
WITH SUBSTANTIAL SHEAR PRESENT...A THREAT OF SEVERE WEATHER EXISTS
INTO TONIGHT...AND A TORNADO WATCH HAS BEEN ISSUED FOR NORTHEAST
GEORGIA AND WESTERN PORTIONS OF THE UPSTATE INTO LATE EVENING...
NEAR THE THERMAL MOISTURE BOUNDARY AT THE PERIPHERY OF THE WEDGE.
MINIMUM TEMPERATURES WILL BE RATHER WARM UNDER CLOUDS AND WITH THE
WIND UP IN A TIGHTENING GRADIENT.

A SURFACE WAVE IS EXPECTED TO MOVE ALONG THE FRONT SATURDAY...
REACHING OUR AREA FROM THE SOUTHWEST AROUND DAWN...WHILE THE FRONT
SLOWS. THIS WILL SET THE NORTHERN AND CENTRAL PORTIONS OF THE AREA
UP FOR A PROLONGED PERIOD OF STRATIFORM RAIN NORTH OF THE SURFACE
WAVE...WHILE THE SOUTHEASTERN PORTION OF THE AREA REMAINS IN THE
UNSTABLE WARM SECTOR. HIGH POPS WILL BE CARRIED THROUGH THE
DAY...WITH TEMPERATURE GAIN LIMITED...ESPECIALLY OUTSIDE THE WARM
SECTOR.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 300 PM FRIDAY...TIMING APPEARS TO BE THE MAJOR DIFFERENCE IN
THE MDLS EARLY IN THE SHORT RANGE. GFS IS THE FASTEST WITH THE
DEPARTING SHORT WAVES SAT NITE. THE NAM...SREF AND ECMWF ALL ARE
DEEPER AND SLOWER WITH THE WAVES. THIS RESULTS IN A SLOWER SURFACE
LOW TRACKING UP THE EAST COAST SAT NITE. WILL TREND TOWARD THE
SLOWER MODELS AND KEEP HIGH POP EARLY FRI EVENING...THEN DIMINISH TO
NO POP AFTER MIDNIGHT. DAMMING HIGH PRESSURE SETS UP ACROSS THE AREA
SUNDAY AND HOLDS ON THRU MONDAY. LOOKS LIKE CLOUDS WILL CLEAR SUNDAY
BEFORE FLOW ABOVE THE HIGH PRESSURE DOME TURNS SLY AND LOW LEVEL
MOISTURE RETURNS SUNDAY NIGHT INTO MONDAY. SUNDAY SHOULD BE DRY WITH
PATCHY LIGHT RAIN RETURNING SUNDAY NIGHT AND MONDAY. LOWS SHOULD BE
ABOVE NORMAL SAT AND SUN NITES. HIGHS NEAR NORMAL SUNDAY THEN A
LITTLE COOLER MONDAY WITH INCREASING CLOUDS.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 230 PM FRIDAY...NOT MUCH CHANGE FROM THE PREVIOUS DAYS MEDIUM
RANGE FORECAST. THE MAIN SYNOPTIC FEATURE CONTINUES TO BE THE
PERSISTENT WEDGE OF WEAK HIGH PRESSURE OVER THE CAROLINAS THAT
STICKS AROUND THROUGH THURSDAY OF NEXT WEEK. THE WEDGE SHOULD
EVENTUALLY BREAK DOWN AS A WEAK COLD FRONT ASSOCIATED WITH A LOW
WELL TO OUR NORTH PUSHES THE WEDGE FURTHER OFFSHORE. DECIDED NOT TO
ALTER POPS VERY MUCH FOR TUES...WED...OR THURS...BUT I DID INCREASE
THEM TO SOLID CHANCE FOR FRI AND EARLY SAT. HPCS POPS CONTINUE TO BE
A BIT MORE OPTIMISTIC FOR MOST OF THE PERIOD...HOWEVER I AM STILL
NOT CONVINCED THERE WILL BE ENOUGH LOW LEVEL DYNAMIC FORCING TO
PRODUCE PRECIP. AS FAR AS TEMPS GO...VALUES SHOULD REMAIN CLOSE TO
CLIMATOLOGY IF NOT A FEW DEGREES ABOVE AS LONG AS THE PREDOMINATE
WINDS STAY FROM THE SOUTHEAST.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
A LINE OF THUNDERSTORMS WILL IMPACT THE UPSTATE TAF SITES FOR THE
FIRST 1 TO 3 HOURS OF THE 00Z TAF PERIOD. THE STORMS MAY IMPACT KCLT
BY 03Z...BUT THE STRENGTH WHEN THEY ARRIVE IS UNCERTAIN. I DID MY
BEST TO TIME THE CONVECTION AND TREND WIND/VSBY/CIGS WHEN THE STORMS
MAKE IMPACT. THE FRONT RESPONSIBLE FOR MOST OF THIS ACTIVITY IS
STILL WELL WEST OF THE AREA...AND WILL TRACK VERY SLOWLY EASTWARD
OVERNIGHT. MODEL GUIDANCE SHOWS THAT THE AIRMASS WILL STAY SLIGHTLY
UNSTABLE OVERNIGHT...SO THERE COULD BE SCATTERED SHOWERS AND TSTMS
THROUGHOUT THE NIGHT (ESPECIALLY E OF THE MTNS). IVE KEPT CB IN
THROUGH 5-6Z. THERE WILL PLENTY OF CLOUDS...BUT CIGS ARE HARD TO
PEG...AS THERE ARE SEVERAL LAYERS OF CLOUDS BEHIND THE CONVECTION.
GUIDANCE IS VERY PESSIMISTIC ON BRINGING IFR/LIFR CIGS OVERNIGHT. I
DID NOT GO THAT LOW...BUT WILL KEEP AN EYE ON THE TRENDS. VSBYS WILL
VARY MOSTLY DUE TO SHOWER/TSTM ACTIVITY.

THE FRONT PASSES THROUGH THE MTNS BY LATE SATURDAY MORNING...AND
STALLS OUT ACROSS THE PIEDMONT. THE MODELS ARE SHOWING A WAVE
DEVELOPING OVER CENTRAL AL ALONG THE FRONT SATURDAY MORNING...AND
TRACKING NE THROUGH UPSTATE SC SATURDAY EVENING. THIS LOW PRESSURE
WILL ALLOW MOIST UNSTABLE AIR TO LIFT NORTH ACROSS THE AREA SATURDAY
AFTN...KEEPING WINDS SOUTHERLY AND INCREASING THE CHC OF SHOWERS AND
TSTMS. I ADDED CB FOR THE AFTN GROUPS AT ALL PIEDMONT SITES. KAVL
AND KHKY LOOK TO STAY NORTH OF THE BNDRY...BUT MAY HAVE SOME SHOWERS.

OUTLOOK...CONDITIONS MAY IMPROVE BRIEFLY SAT NIGHT/SUNDAY...BUT
ANOTHER COLD AIR DAMMING EPISODE APPEARS LIKELY FOR MUCH OF NEXT
WEEK.

&&

.GSP WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
NC...NONE.
SC...NONE.
