What was reported inside it

Time	Report	Where	Remark
Sep 2, 5:52 PM EDT	TSTM WND DMG	3 Nnw Mocksville, NC	MULTIPLE TREES AND POWER LINES DOWN ON LIBERTY CHURCH ROAD NEAR US HWY 601.

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

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 9 minutes after it went out.

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 nearest sounding before it

Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 9.7 hours before the alert went out and 55 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Sep 2, 4:25 PM EDT, 1 hour 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
425 PM EDT SUN SEP 2 2012

.SYNOPSIS...
THE REMNANTS OF ISAAC WILL CONTINUE TO MOVE SLOWLY EASTWARD ACROSS
THE OHIO VALLEY THROUGH MONDAY. MOISTURE OUT AHEAD OF THIS SYSTEM
WILL STEADILY INCREASE ACROSS THE WESTERN CAROLINAS AND NORTHEAST
GEORGIA THROUGH WEDNESDAY BEFORE A WEAK COLD FRONT ARRIVES FROM THE
NORTHWEST FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
AS OF 420 PM...LINE OF CONVECTION MOVING INTO THE I-77 CORRIDOR
ATTM. HAVE UPDATED POPS TO REFLECT THIS LINE MOVING ACROSS THE CWFA.
KEEP AFTER A BRIEF LULL BEHIND THE LINE...RETURN LIKELY POP TO THE
MTNS AND HIGH CHC POP ELSEWHERE. THIS IN ASSOCIATION WITH ANOTHER
LINE OF CONVECTION MOVING INTO THE MTNS AND CONVECTION DEVELOPING
OUTSIDE OF THE MTNS AHEAD OF THIS LINE. UPDATED TEMPS TO ACCOUNT FOR
COOLING WITH THE FIRST LINE AND A BRIEF WARM UP BEHIND...BUT NOT AS
WARM AS THE TEMPS AHEAD OF THE FIRST LINE. UPDATED SKY AND WINDS TO
ACCOUNT FOR THESE FEATURES AS WELL. NO CHANGES AFTER EARLY EVENING.

AT 2 PM EDT SUNDAY...THE UPPER LOW ASSOCIATED WITH ISAAC WILL DRIFT
SE FROM THE OH VALLEY TO THE TN VALLEY BY LATE MONDAY. MEANWHILE...A
MOIST SW FLOW AHEAD OF THE SYSTEM WILL BRING DEEP MOISTURE INTO OUR
AREA. A VORT LOBE ROUNDING THE UPPER LOW WILL MOVE A LINE OF
CONVECTION FROM THE BLUE RIDGE TO THE PIEDMONT THIS AFTERNOON. THE
BEST INSTABILITY WILL BE IN THE PIEDMONT...WHERE MORE DRY AIR EXISTS
ALOFT FOR EVAPORATIVE COOLING.  BETTER UPPER SUPPORT WILL MOVE
ACROSS THE MOUNTAINS TONIGHT AND MONDAY. NOTABLE UNIDIRECTIONAL
SHEAR WILL BE PRESENT ON MONDAY...WITH SUBSTANTIAL CAPE EAST OF THE
MOUNTAINS...BUT PROFILES WILL BE NEARLY SATURATED...WITH LITTLE DRY
AIR AVAILABLE. SW STEERING FLOW WILL KEEP CELLS MOVING... BUT
TRAINING CELLS COULD PRODUCE EXCESSIVE RAINFALL...ESPECIALLY IN
MOUNTAINOUS TERRAIN AND URBAN AREAS. TEMPERATURES WILL EXHIBIT A
LIMITED DIURNAL RANGE...WITH ABOVE NORMAL MINIMUMS AND NEAR OR
SLIGHTLY BELOW NORMAL MAXIMUMS IN A MOIST AIR MASS WITH CLOUD COVER.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
AS OF 200 PM EDT SUNDAY...UPPER LEVEL HEIGHTS CONTINUE TO FALL AS
THE REMNANT TC TROF GETS SLOWLY DRAGGED INTO THE CWFA LATE MON. THE
UPPER FLOW REMAINS ILL DEFINED AS THE TROF DISSIPATES AND LEAVES THE
AREA UNDER A GENERAL...YET HIGHLY TROPICAL WEAKNESS. VERY HIGH PWATS
WILL BE MAINTAINED AND THE NAM/GFS BOTH INDICATE A CONTINUOUS SW/LY
FLOW OF THETA/E ADV INTO THE AREA TUE AND WED. MODEL THERMAL
PROFILES STILL SHOW WEAK YET DEEP LAYERED SBCAPE AND SOME MODERATE
MUCAPE. THERE LOOKS TO BE SOME LLVL SHEAR AS THE BRIEFLY DEFINED SFC
SYSTEM WORKS IN EARLY TUE...BEFORE WEAKENING THROUGH A DEEP LAYER
WITH THE LOSS OF UPPER SUPPORT. THIS WILL LEAVE THE AREA WITH A
RATHER HIGH POTENTIAL OF EFFICIENT AND HEAVY RAINFALL PRODUCING
STORMS THAT COULD BACK BUILD OR HAVE LITTLE MOTION. THUS...THERE
WILL BE AN ONGOING ISOL FLOODING CONCERN ACROSS THE MAJORITY OF THE
FCST AREA BOTH TUE AND WED. SEVERE STORMS ARE NOT LIKELY WITH LITTLE
SHEAR PRESENT...BUT SOME RATHER TALL STORMS COULD DEVELOP IN
DIFFERENTIAL HEATING AREAS AND PRODUCE A LOCALIZED WIND OR HAIL
THREAT EACH AFTERNOON. THE BEST WIDESPREAD CLOUD COVER SHOULD BE ON
TUE AND MAX TEMPS WILL HAVE A HARD TIME REACHING NORMAL
LEVELS...PROBABLY A CAT OR SO BELOW. ON WED...MORE BREAKS IN THE
CLOUDS SHOULD ALLOW TEMPS BACK NEAR NORMAL. MIN TEMPS WILL LIKELY BE
A CAT OR SO ABOVE NORMAL WITH A LOW RADIATIONAL COOLING POTENTIAL
EACH MORNING.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
AS OF 1230 PM EDT SUNDAY...THERE IS DECENT CONFIDENCE THE REMAINING
DEEP LAYERED MOISTURE ASSOCIATED WITH ISAAC REMNANTS SHUNTED EAST
WHILE LOWER THETA/E AIR WORKS IN FROM THE NW. THE GFS IS MORE
AGGRESSIVE AND PRONOUNCED WITH A SFC RIDGE AXIS BUILDING IN AND A
COMPROMISE WITH THE WEAKER ECMWF STILL DRIES THINGS OUT RELATIVELY
QUICKLY AFT 18Z THU. MODEL SOUNDINGS SHOW DEEP LAYERED DRYING FROM
ALOFT THROUGHOUT THE DAY AND PWATS DROP TO LESS THAN 1.5 INS AFT
21Z. THERE WILL BE SOME MODERATE MUCAPE ACROSS THE ERN ZONES...BUT
LITTLE IS EVIDENT IN THE SHEAR PROFILES TO SUPPORT AN ORGANIZED OR
WIDESPREAD CONVECTIVE CONCERN THU EVENING.

A MOSTLY DRY DAY IS IN STORE FRI WITH N/LY FLOW ENCOMPASSING THE
AREA WHILE HIPRES CONTINUES TO BUILD IN. HOWEVER...A LOW END
CONVECTIVE CHANCE WILL BE MAINTAINED ACROSS THE NC MTNS DUE TO GOOD
INSOL COMBINED WITH MECH LIFT. ANOTHER FRONTAL SYSTEM APPROACHING
THE CWFA MAY BE IN STORE OVER THE WEEKEND. THE OP GFS SOUNDING SHOWS
A RELATIVELY STABLE AIR MASS AHEAD OF THIS SYSTEM...HOWEVER FAIRLY
HIGH DEEP LAYERED SHEAR DEVELOPS BY SAT EVENING WHICH COULD HELP
PRODUCE AREAS OF STRONGER TSTMS. FOR NOW...KEPT PRETTY MUCH
CLIMO/HPC POPS SAT WITH A LITTLE HIGHER CHANCES FOR SUN.

WITH INCREASING INSOL...MAX TEMPS WILL BE RIGHT AROUND NORMAL THU.
WITH A WEAK CP AIR MASS MIXING IN...MAXES A COUPLE DEGREES BELOW
NORMAL ARE ADVERTISED FOR FRI AND POSSIBLY SAT AS WELL. MINS SHOULD
STILL BE A COUPLE DEGREES ABOVE NORMAL THU...WITH NORMAL MIN TEMPS
RETURNING FRI/SAT.

&&

.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
AT KCLT...CONVECTIVE CHANCES WILL BE THE BEST IN DAYS WITH LIMITED
CLOUD COVER AND COOLER MID LEVELS ALLOWING FOR GREATER INSTABILITY.
A TEMPO FOR CONVECTION WITH GUSTY WINDS WILL BE CARRIED MID TO LATE
AFTERNOON. ALTHOUGH INSTABILITY DECREASES WITH THE LOSS OF HEATING
TONIGHT...A MOIST SW FLOW AHEAD OF AND APPROACHING UPPER LOW WILL
KEEP SOME CHANCE GOING ALL NIGHT... ALTHOUGH NOT GREAT ENOUGH TO
MENTION IN THE TAF. GUIDANCE IS SUPPORTIVE OF MVFR VSBY TOWARD
DAYBREAK MONDAY...AND WITH A BETTER CHANCE OF RAIN...THIS SEEMS
REASONABLE. GUIDANCE KEEPS THE CIG VFR. MONDAY LOOKS EVEN BETTER FOR
PRECIPITATION CHANCES...BUT MAINLY AFTER THIS FORECAST PACKAGE.

ELSEWHERE...A LINE OF CONVECTION WILL WARRANT TEMPO AT ALL SITES
EARLY IN THE FORECAST. ALTHOUGH RAIN CHANCES DECREASE WITH THE LOSS
OF HEATING TONIGHT...THEY NEVER COMPLETELY GO AWAY AN UPPER LOW
APPROACHES...BUT NIGHTTIME CHANCES WILL BE TOO LOW TO MENTION IN THE
TAFS. GUIDANCE SUPPORTS MVFR FOG IN THE FOOTHILLS BEFORE DAWN...AND
IFR OR LOWER IN THE MOUNTAINS. CIG RESTRICTIONS WILL BE LIMITED TO
THE MOUNTAINS AND KHKY. PRECIPITATION CHANCES INCREASE ON
MONDAY...MAINLY AFTER THIS FORECAST PACKAGE.

OUTLOOK...MOISTURE WILL REMAIN HIGH THROUGH A DEEP LAYER ACROSS THE
REGION MONDAY THROUGH AT LEAST WEDNESDAY. LOW CLOUD/FOG RESTRICTIONS
WILL OCCUR MAINLY WITH PASSING CONVECTION AND ALSO DURING THE PRE
DAWN HOURS WHERE PRECIPITATION FELL THE DAY BEFORE. GRADUAL DRYING
FROM THE WEST IS POSSIBLE THURSDAY.
