Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 41 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.

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 Birmingham, AL wrote its last area forecast discussion before this flash flood warning went out at Apr 17, 3:16 PM CDT, 14 minutes earlier.

Area forecast discussion, Apr 17, 3:16 PM CDT, 14 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
316 PM CDT WED APR 17 2013

.DISCUSSION...

THE WORD FOR TODAY IS...OROGRAPHIC.  MUCH LIKE YESTERDAY...TODAY'S
WEATHER PATTERN AROUND CENTRAL ALABAMA HAS BEEN MIRED IN HIGH
PRESSURE ALOFT AND AT THE SURFACE.  SUMMER-LIKE HEATING HAS ALLOWED
FOR SURFACE CAPE VALUES TO CLIMB INTO THE 1500-2000 J/KG RANGE
AGAIN...BUT THE DIFFERENCE TODAY IS...THE POSITION OF THE SURFACE
RIDGE. SITUATED JUST OFF TO OUR EAST...SOUTHEASTERLY SURFACE FLOW
INTO THE FOOTHILLS OF THE APPALACHIANS HAS CREATED OROGRAPHIC LIFT
IN OUR NORTHEASTERN COUNTIES. LIFT IS WHAT WE WERE MISSING
YESTERDAY...AND TODAY...AMONGST THE ATMOSPHERIC INSTABILITY...WE
ARE FINALLY GETTING A FEW THUNDERSTORMS. THESE STORMS WILL LIKELY
PRODUCE OUTFLOW BOUNDARIES OF THEIR OWN...CREATING ANOTHER SOURCE
OF LIFT...SO ISOLATED TO SCATTERED THUNDERSTORMS CAN BE EXPECTED
TO DEVELOP UNTIL THE SUN GOES DOWN. SOME OF THESE COULD BE STRONG
AT TIMES...WITH SMALL HAIL...A BRIEF STRONG WIND GUST AND
LOCALIZED FLASH FLOODING AS THESE STORMS ARE NOT MOVING MUCH AT
ALL...SO THOSE IN OUR NORTHEAST COUNTIES NEED TO BE WEATHER AWARE
THROUGH SUNSET.

OUR MAIN FOCUS WILL BE ON THE COLD FRONT-INDUCED SQUALL LINE
EXPECTED IN HERE THURSDAY NIGHT AND FRIDAY MORNING. THE TRANSITION
TO THIS FRONT WILL BEGIN THURSDAY MORNING AS THE ASSOCIATED UPPER
LEVEL SYSTEM DIGS INTO THE CENTER OF THE COUNTRY. THIS DIGGING
WILL AMPLIFY THE RIDGE A BIT...CURRENTLY IN PLACE OVER US
NOW...AND REMOVE THE CHANCE FOR PRECIPITATION THURSDAY AFTERNOON.
WITHOUT ANY RAIN THURSDAY AFTERNOON...THE ATMOSPHERE WILL BE
ALLOWED TO RIPEN AHEAD OF THE APPROACHING COLD FRONT...AND LEAVE
US WITH DECENT INSTABILITY IN PLACE. BY THURSDAY EVENING...A WELL-
DEVELOPED SQUALL LINE WILL HAVE COME TOGETHER UPSTREAM OF THE
STATE AND BEGIN MOVING TOWARDS CENTRAL ALABAMA. CURRENT PROJECTIONS
SHOW THE SQUALL LINE TRYING TO MOVE INTO OUR NORTHWESTERN COUNTIES
BY 11 PM THURSDAY NIGHT. AGAIN...THE QUESTION REMAINS TO BE HOW
WELL THE LINE WILL HOLD TOGETHER AS IT MOVES THROUGH THE STATE
DURING THE OVERNIGHT HOURS. THERE WILL BE A LOSS OF SURFACE BASED
INSTABILITY...BUT I DO BELIEVE THE LINE WILL HOLD TOGETHER LONG
ENOUGH TO CREATE A DECENT SEVERE WEATHER THREAT FOR THOSE COUNTIES
ALONG AND WEST OF INTERSTATE 65. DAMAGING STRAIGHT LINE WINDS WILL
BE THE MAIN THREAT...BUT WITH 35-40KTS OF 0-1KM BULK SHEAR...
BOWING SEGMENTS AND EMBEDDED SUPERCELLULAR STRUCTURES WILL BE A
POSSIBILITY...SO ISOLATED TORNADOES WILL ALSO BE A THREAT. AS THE
FRONT MOVES INTO OUR EASTERN COUNTIES...FORECAST REASONING WOULD
SUGGEST THAT THE LINE WILL BEGIN TO DIMINISH. THE UPPER LEVEL AND
OVERALL SYSTEM SUPPORT SHOULD BE FAR ENOUGH NORTH OF THE STATE TO
REDUCE THE SEVERE THREAT...BUT I CANNOT RULE OUT A CHANCE THAT THE
LINE HOLDS TOGETHER AND PRODUCES SOME ISOLATED WIND DAMAGE EAST OF
I-65 DURING THE MORNING HOURS ON FRIDAY. THE FRONT ITSELF SHOULD
BE CLEAR OF CENTRAL ALABAMA BY NOON...ELIMINATING THE SEVERE
THREAT...BUT LINGERING POST-FRONTAL SHOWERS MAY REMAIN FOR THOSE
SOUTH OF INTERSTATE 85 THROUGH FRIDAY AFTERNOON.

THIS WEEKEND LOOKS TO BE BEAUTIFUL...WITH MUCH MORE SPRING-LIKE
TEMPERATURES AND DRY CONDITIONS.

OUR NEXT RAIN THREAT COULD BE MONDAY AS A WEAK TROUGH SWINGS THROUGH
THE SOUTHEAST...WITH A BIGGER RAIN/THUNDERSTORM THREAT BY TUESDAY
NIGHT OR WEDNESDAY NEXT WEEK.

27

&&

.AVIATION...
18Z TAF DISCUSSION.

BASED ON PERSISTENCE OVER THE LAST COUPLE DAYS...HAVE KEPT VFR
CONDITIONS IN THROUGH THE TAF PERIOD. MODEL GUIDANCE HAS OVERDONE
LOWER CIGS AND VIS THE PAST SEVERAL NIGHTS...AND WITH THE MAIN
MOISTURE PLUME TO OUR WEST AND WARM TEMPERATURES OVERNIGHT...
CONFIDENCE AND CHANCES FOR ANY REDUCTIONS IN PREVAILING VFR
CONDITIONS REMAIN TOO LOW.

ISOLATED TO SCATTERED SHOWERS AND TS ARE POSSIBLE THIS AFTERNOON...
ESPECIALLY ACROSS THE NORTH. CHANCES AT ANY TERMINAL ARE TOO LOW
TO INCLUDE AT THIS TIME. WILL MONITOR DEVELOPMENT UPSTREAM AND
MAKE ADJUSTMENTS IF NEEDED. ACTIVITY WILL DIMINISH WITH SUNSET.
