What was reported inside it

Time	Report	Where	Remark
Aug 8, 6:05 PM CDT	HEAVY RAIN 1	3 Wsw Guntersville, AL	ONE INCH OF RAIN FELL FROM 605PM UNTIL 615PM IN GUNTERSVILLE...MEASURED FROM CRN SITE.
Aug 8, 6:43 PM CDT	HEAVY RAIN 0	3 Wsw Guntersville, AL	ONE INCH OF RAIN IN 10 MINUTES CAUSED RAPIDLY RISING WATER TO APPROACH THE BAY AREA OF THE GUNTERSVILLE FIRE DEPARTMENT. THE RESCUE BOAT WAS USED TO PUMP WATER FROM THE PARKING LOT TO KEEP THE FIRE STATION FROM BEING FLOODED.

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 flash flood 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 nearest sounding before it

Birmingham, AL (KBMX), launched 12:00Z, 10.9 hours before the alert went out and 147 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.

Skew-T log-p

Temperature in red, dew point in green, the mixed-layer parcel dashed.

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 Huntsville, AL wrote its last area forecast discussion before this flash flood warning went out at Aug 8, 3:48 PM CDT, 2 hours 4 minutes earlier.

Area forecast discussion, Aug 8, 3:48 PM CDT, 2 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
348 PM CDT THU AUG 8 2013

.DISCUSSION...
THE HEAVIER AXIS OF SHOWER AND THUNDERSTORMS HAS REMAINED NORTH IN
TENNESSEE FOR MOST OF THE DAY WITH A LINE OF THUNDERSTORMS CURRENTLY
(AT 20Z) BUILDING IN FRANKLIN CO TN SOUTHWARD TO LAWRENCE CO AL.
THESE THUNDERSTORMS WILL LINGER INTO THIS EVENING. MODELS ARE NOT
HANDLING THE NW FLOW CONVECTIVE PATTERN VERY WELL SO THE FORECAST
12-24 HOURS OUT IS VERY MESOSCALE DOMINANT. POP/WX GRIDS MAY HAVE TO
BE MONITORED FOR ADJUSTMENTS. WITH THE DEWPOINTS REACHING IN THE
UPPER 70S TODAY AND LINGERING MOISTURE...IF CLOUD COVER DECIDES TO
CLEAR OUT AT ALL AGAIN TONIGHT...PATCHY FOG IS POSSIBLE.

TOMORROW THE TN VALLEY IS STILL IN A CONVERGENCE AXIS BETWEEN TWO
RIDGES...ONE OVER TX AND ANOTHER OVER THE ATLANTIC. FRI MORNING POPS
AND CLOUD COVER WERE DECREASED WITH HIGH TEMP MARGINALLY INCREASED. AS
THE WESTERN RIDGE BEGINS TO BREAK DOWN...FRI NIGHT POPS WERE
INCREASED AS NORTHWESTERLY FLOW MAY BRING DOWN ANOTHER WAVE OF
VORTICITY ENERGY.

BY SATURDAY A WEAKLY DEFINED FRONT SETS UP IN MID TN AND DRAPES SW.
MORE CLOUD COVER WAS ADDED AND POPS WERE INCREASED. THAT WEAK FRONT
WILL REMAIN BASICALLY PARKED IN PLACE SUNDAY AND MONDAY. IT IS
POSSIBLE THAT CONVERGENCE ALONG THE FRONT WILL WEAKEN TO THE POINT
THAT IT DOES NOT ENHANCE DIURNAL PRECIP, BUT FOR NOW, WE WILL ASSUME
THAT THIS WEAK FRONT WILL CONTINUE TO IMPROVE RAIN CHANCES. IT WILL
TAKE THE ARRIVAL OF A MORE ROBUST SHORTWAVE IN THE NW FLOW TO DRIVE
THE FRONT THRU--OR NOT, DEPENDING ON THE MODEL YOU PREFER. MODEL/
ENSEMBLE CONSENSUS AGREES ON THE ARRIVAL OF THE SHORTWAVE LATE
MONDAY/EARLY TUESDAY. THAT CONSENSUS TIMING IS ABOUT 12 HRS DELAYED
FROM YESTERDAYS RUNS.

THE BIG QUESTION LIES WITH THE SOUTHWARD PROGRESSION OF THE FRONT AS
THE LONGWAVE TROUGH CARVES OUT ACROSS THE EASTERN U.S. THE MORE
AGGRESSIVE ECMWF HAS A MORE N/NW FLOW WITH THE TROUGH, AND THUS
DRIVES THE FRONT THROUGH THE AREA WITH UNCOMMON FORCE FOR MID-
AUGUST. THE GFS, FOR ONCE, IS THE MORE CONSERVATIVE CHOICE AND
STALLS IT OUT LOCALLY, MAINTAINING HIGH POPS AND MORE TYPICAL
DEWPOINTS OVER THE AREA THROUGH THURSDAY. MODEL AND ENSEMBLE
AGREEMENT ON THIS ATYPICAL PATTERN IS QUITE STRONG, SO CONFIDENCE IS
FAIRLY HIGH THAT THE FRONT WILL WORK INTO THE AREA--BUT WE REMAIN
SKEPTICAL THAT THE FRONT WILL PUSH ALL THE WAY TO THE COAST AS
DEPICTED BY THE ECMWF (THOUGH IT HAS BEEN THE SUMMER OF STRONG COLD
FRONTS). SO WE WILL MAINTAIN LOW POPS, HIGHER DEWPOINTS, AND HIGHER
TEMPERATURES IN THAT TIME PERIOD, FOR NOW.

.AVIATION...
/ISSUED 1230 PM CDT THU AUG 8 2013/
FOR 18Z TAFS...VFR CONDS ARE GENERALLY XPCTED TO PREVAIL AT BOTH MAIN
TERMINALS THROUGH THE FORECAST PERIOD. SCT CU FIELD INCREASING ACROSS
THE AREA ALONG WITH MID/HIGH LEVEL DEBRIS CLOUDS STREAMING S/E WILL
BE THE GENERAL TREND THROUGH THE AFTERNOON PERIOD...ALTHOUGH CIGS ARE
PREDOM XPCTED TO REMAIN ABOVE VFR LEVELS. SCT SHRA/TSRA WILL ALSO
DEVELOP ACROSS THE AREA THIS AFTERNOON...ALTHOUGH UNCERTAINTY IN THE
PLACEMENT/TIMING OF ANY CONVECTION WARRANTS JUST A VCTS AROUND 21Z AS
OF NOW. CONVECTION IS THEN XPCTED TO TAPER OFF THIS EVENING...WITH
QUIET CONDS PREVAILING INTO THE MORNING HRS FRI. ONLY OTHER CONCERN
MAY BE SOME -BR DURING THE OVERNIGHT HRS...ALTHOUGH THIS REMAINS
UNCERTAIN AS WELL GIVEN THE LACK OF BR/FG DEVELOPMENT THE PAST COUPLE
OF MORNINGS.
