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 Sep 20, 3:17 PM CDT, 2 hours 58 minutes earlier.

Area forecast discussion, Sep 20, 3:17 PM CDT, 2 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
317 PM CDT SUN SEP 20 2009

.DISCUSSION...

IN THE SHORT TERM WE WILL REMAIN UNDER THE STATUS QUO AS THE
MAIN TROF STAYS ACROSS THE CENTRAL PLAINS...FEEDING MUCH OF THE
SOUTHEAST WITH SOUTHWESTERLY FLOW AND DEEP LAYER MOISTURE. AS THE
DAYS WEAR ON...HAVE NOTICED A DECENT MID LEVEL JET...RECOGNIZABLE
ON THE LATEST WV IMAGERY...WORK ACROSS THE SOUTHWEST CONUS AND
AROUND THE BASE OF THE TROF. THIS HAS STARTED TO BRING A LITTLE
DRIER AIR ALOFT...MODERATING THE PW VALUES A BIT. HOWEVER...IT
WONT BE BEFORE ANOTHER SHORT WAVE OR TWO ROTATE ACROSS CENTRAL
ALABAMA BRINGING ADDITIONAL LINES OF HEAVY RAIN THROUGH AT LEAST
TOMORROW EVENING.

AS THIS MAIN TROF RETROGRADES WESTWARD DURING THE COMING WORK
WEEK...WE WILL REMAIN GENERALLY UNDER SOUTHWEST FLOW
ALOFT...HOWEVER...MODELS CONTINUE TO SUGGEST A WEAK RIDGE OF HIGH
PRESSURE BUILDING IN FROM THE SOUTH. WITH THIS WRINKLE...HAVE
CONTINUED TO KEEP MUCH SMALLER POPS IN THE FORECAST BEGINNING MID
WEEK THROUGH THE FIRST HALF OF NEXT WEEKEND. SO...THE END OF THIS
PATTERN MAY BE ON THE HORIZON.

IN THE LONGEST TERM...THE PATTERN GETS MIGHTY PROGRESSIVE IN THE
OPERATIONAL AND ENSEMBLE RUNS. ALTHOUGH THE TIMING IS
OFF...GUIDANCE SHOWS A DEEP TROF MOVING ACROSS MUCH OF THE EASTERN
HALF OF THE CONUS...FOLLOWED BY A QUIET RIDGE OF HIGH PRESSURE.
WILL MONITOR WITH INTEREST.

17/KLAWS

&&

.AVIATION...18Z TAF DISCUSSION.

AFTER A MORNING LULL...SCATTERED SHOWERS STARTED TO DEVELOP AROUND
20/1700Z.  I EXPECT AN INCREASE IN RAIN COVERAGE THROUGH THE
REMAINDER OF THE AFTERNOON...WITH AN EVENTUAL IMPACT ON MOST (IF NOT
ALL) TAF SITES BEFORE 21/0200Z.  WITH A TROPICAL AIR MASS...THESE
SHOWERS ARE VERY EFFICIENT AT PRODUCING HEAVY RAIN...AND ALSO IN
LOWERING VISIBILITY AS THEY MOVE THROUGH.

THERE MAY BE PERSISTENT AREAS OF RAIN OVERNIGHT...BUT DUE TO LOW
CONFIDENCE I DID NOT INCLUDE ANY PRECIPITATION AFTER 21/0200Z WITH
THIS FORECAST.  A BIT HIGHER CONFIDENCE IN THE REDEVELOPMENT OF
LOWER CEILINGS OVERNIGHT...WITH MY BEST GUESS AT AN AVERAGE
PREDOMINANT CONDITION OF JUST BELOW 1000 FEET BECOMING FAIRLY
WIDESPREAD AFTER 21/0800Z.
