What was reported inside it

Time	Report	Where	Remark
Jul 14, 9:00 PM CDT	FLASH FLOOD	2 N Madison, AL	MOVING WATER COVERING SEVERAL 30-40 FT SECTIONS OF HARBIN RD IN MADISON.

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 flash flood warning; the first came 13 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

Nashville Metro, TN (KBNA), launched 00:00Z, 1.8 hours before the alert went out and 155 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.

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 Jul 14, 6:20 PM CDT, 2 hours 27 minutes earlier.

Area forecast discussion, Jul 14, 6:20 PM CDT, 2 hours 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
620 PM CDT THU JUL 14 2011

.UPDATE...FOR 00Z AVIATION DISCUSSION
&&

.AVIATION...
SCATTERED THUNDERSTORMS WILL CONTINUE ACROSS THE GREATER TENNESSEE
VALLEY THROUGH THE EVENING HOURS...WITH ADDITIONAL DEVELOPMENT
EXPECTED FRIDAY MORNING. WITH BOUNDARIES BEING THE MAIN TRIGGER FOR
STORM DEVELOPMENT THIS EVENING...CONFIDENCE IN TS LOCATION IS
LOW...SO HAVE UTILIZED CB/VCSH AND WILL AMD AS NEEDED. PATCHY FOG
WILL DEVELOP DURING THE OVERNIGHT HOURS. THIS FOG MAY FALL BELOW
MVFR...AND WILL ADDRESS THAT FURTHER WITH THE 06Z TAF PACKAGE.
&&

.DISCUSSION.../ISSUED 301 PM CDT THU JUL 14 2011/
THE SFC BOUNDARY CAUSING MUCH OF THE CONVECTION DURING
THE AFTERNOON AND EVENING HOURS WILL LIKELY CONTINUE PUSHING
NORTHWEST AS A WARM FRONT. THOUGH THIS BOUNDARY IS VERY DIFFICULT TO
ASCERTAIN, THE NAM/GFS ARE INDICATING THAT THE LOW WILL LIKELY MOVE
NORTHWEST TOWARDS N AL DURING THE OVERNIGHT HOURS AND MAY PROVIDE
THE FOCUS FOR STORMS TONIGHT. IT APPEARS THAT THE MAIN REASON FOR
THE MOVEMENT OF THIS FRONT NORTHWARD IS THE BUILDING OF THE SFC HIGH
PRESSURE SYSTEM EAST TOWARDS THE WESTERN ATLANTIC TONIGHT INTO
TOMORROW.

WITH THE FRONT MOVING CLOSER TO THE SOUTHERN PERIPHERY OF OUR
FORECAST AREA (MARSHALL, CULLMAN, DEKALB, FRANKLIN AL, LAWRENCE,
MORGAN) HAVE ADJUSTED POPS TO THE LIKELY CATEGORY. THESE STORMS ARE
EXPECTED TO CONTINUE DEVELOPING ACROSS N AL THROUGHOUT THE DAY ON
FRIDAY INTO THE EVENING BEFORE IT CLEARS BY 00-02Z. THUNDERSTORM
ACTIVITY SHOULD CONTINUE UNTIL JUST AFTER SUNSET ONCE THE FRONT
MEANDERS NORTH. ONE THING TO NOTE IS THAT THE MODELS TEND TO HAVE
GREAT DIFFICULTY HANDLING FRONTAL MOVEMENT THIS TIME OF YEAR. THUS,
DID KEEP THUNDERSTORM CHANCES THROUGH FRIDAY NIGHT INTO SATURDAY.
HOWEVER, THIS MAY NEED TO BE ADJUSTED. TEMPS ON SATURDAY WILL LIKELY
BE LOWER GIVEN THE AMOUNT OF CLOUD COVER THAT IS POSSIBLE THROUGHOUT
THE DAY. ANY THUNDERSTORMS THAT DEVELOP WILL HAVE VERY HEAVY
RAINFALL AND POTENTIAL FOR MICROBURST GIVEN THE VERY HIGH PWATS,
MODERATELY INVERTED V PROFILES, AND LACK OF WIND SHEAR.

AS THE HIGH PRESSURE SYSTEM MOVES TOWARD BERMUDA, SOUTHEASTERLY TO
EASTERLY FLOW WILL DEVELOP (AT LEAST AT THE LOW LEVELS) BRINGING
SOMEWHAT COOLER AND DRIER AIR OFF THE APPALACHIANS OVER N AL. THUS,
HAVE KEPT THE COOLER (ABOUT 5 DEGREES) AND SOMEWHAT DRIER TREND
ESPECIALLY OVER NE AL. AS THE UPPER RIDGE BUILDS OVER THE CENTRAL
PLAINS, NORTHERLY FLOW WILL SETUP OVER THE SOUTHEAST. MODELS ARE
HINTING AT THE POSSIBILITY OF A MCS/SHORTWAVE FEATURE DROPPING SOUTH
ACROSS THE MIDWEST ACROSS W TN/N MS ON SUNDAY MORNING. THUS, WILL
KEEP CHC OF THUNDERSTORMS.

BY MONDAY AND CONTINUING THROUGH MID WEEK, THE STRONG RIDGE CENTERED
OVER THE CENTRAL PLAINS WILL BEGIN TO MEANDER TOWARDS THE EAST AS A
BROAD TROUGH CROSSES MANITOBA AND ALBERTA. THIS WILL RESULT IN A
GRADUAL WARMUP BACK INTO THE VERY HOT AND HUMID CONDITIONS. ONE
THING THAT WILL BE DIFFERENT FOR THE CONDITIONS THIS TIME IS THAT
THE HIGH WILL ALMOST BE PARKED ON TOP OF US, WHICH WILL LIKELY MEAN
LOWER CHANCES FOR THUNDERSTORMS. SO, HAVE PRETTY MUCH KEPT SCHC OF
THUNDERSTORMS ON MONDAY WITH OROGRAPHIC DEVELOPMENT ON TUESDAY OVER
NE AL. LITTLE (IF ANY) DEVELOPMENT IS EXPECTED ON WEDNESDAY/THURSDAY
WHICH WITH HIGHS IN THE MID TO UPPER 90S (HEAT INDICES LIKELY ABOVE
105) MEANING LITTLE RELIEF FROM THE HEAT.

MARSHALL-JACKSON-DEKALB-CULLMAN-MOORE-LINCOLN-FRANKLIN TN-
738 PM CDT THU JUL 14 2011

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH ALABAMA AND PORTIONS
OF SOUTHERN MIDDLE TENNESSEE.

.DAY ONE...TONIGHT...

SCATTERED THUNDERSTORMS WILL IMPACT THE TENNESSEE VALLEY THIS
EVENING. SOME OF THESE STORMS MAY BE STRONG WITH GUSTY
WINDS...FREQUENT CLOUD TO GROUND LIGHTNING AND LOCALLY HEAVY
RAINFALL. THERE IS A SLIGHT RISK FOR FLASH FLOODING DUE TO SLOW
STORM MOVEMENT AND HIGH ATMOSPHERIC MOISTURE LEVELS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

A SOMEWHAT BETTER CHANCE FOR SHOWERS AND THUNDERSTORMS IS EXPECTED
FRIDAY...AS AN UPPER LEVEL DISTURBANCE MOVES ACROSS THE DEEP
SOUTH...AND HIGH MOISTURE LEVELS CONTINUE. THE STRONGER STORMS AGAIN
WILL BE CAPABLE OF PRODUCING STRONG GUSTY WINDS...TORRENTIAL RAINS
AND FREQUENT LIGHTNING. SLOW STORM MOVEMENT AND CELLS MOVING ACROSS
THE SAME AREA WILL CONTINUE TO PRODUCE A RISK OF FLASH FLOODING.

A CHANCE FOR MAINLY AFTERNOON AND EARLY EVENING THUNDERSTORMS WILL
CONTINUE THIS WEEKEND AND THROUGH THE MIDDLE OF NEXT WEEK. HOT
CONDITIONS WILL ALSO CONTINUE THROUGH NEXT WEEK. DAILY HIGH
TEMPERATURES WILL GRADUALLY WARM BACK INTO THE MID 90S AND HEAT INDEX
VALUES WILL CLIMB BACK INTO THE 100-108 DEGREE RANGE BY THE MIDDLE OF
NEXT WEEK.

.SPOTTER CALL TO ACTION STATEMENT...

FORMAL ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT
PERSONNEL IS NOT ANTICIPATED AT THIS TIME. HOWEVER...TIMELY REPORTS
OF WIND DAMAGE AND FLOODING WILL BE GREATLY APPRECIATED.
