The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Nov 16, 10:15 AM CST, 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1015 AM CST WED NOV 16 2011

.UPDATE...MESOSCALE UPDATE.

&&

.DISCUSSION...

THE LATEST MESOANALYSIS DEPICTS THE CENTER OF THE SURFACE LOW ACROSS
EASTERN WINSTON AND WESTERN CULLMAN COUNTIES AS OF 10AM THIS
MORNING...WITH THE SURFACE FRONT SLOWLY BEGINNING TO ENTER INTO
NORTHWESTERN PORTIONS OF THE CWA ACCORDING TO THE LATEST SURFACE
OBS. THE LATEST RUC ANALYSIS NOW INDICATES SHEAR PROFILES INCREASING
ACROSS CENTRAL PORTIONS OF THE STATE THROUGH NOON...AS WELL AS
ACROSS EASTERN AND SOUTHEASTERN PORTIONS OF THE STATE AS WELL. 0-6KM
BULK SHEAR VALUES OF WELL OVER 45 KNOTS WILL CONTINUE ALONG THE
INTERSTATE 65 CORRIDOR...TRANSITIONING EAST AND SOUTHEAST AS WE GO
THROUGHOUT THE AFTERNOON. BULK SHEAR LOOKS TO POSSIBLY INCREASE
ACROSS SOUTHEASTERN PORTIONS OF THE STATE TO OVER 50 KNOTS FROM
18Z-21Z...WITH THE GREATEST SURFACE BASED CAPE OF OVER 1000 J/KG
EXISTING THERE AS WELL. THEREFORE...THE GREATEST THREAT THIS
AFTERNOON FOR AN ISOLATED TORNADO LOOKS TO BE ALONG THE INTERSTATE
85 CORRIDOR...BUT WITH HIGH BULK SHEAR ACROSS ALL OF EASTERN ALABAMA
THIS AFTERNOON...AN ISOLATED TORNADO WILL BE POSSIBLE ACROSS ALL
AREAS THAT HAVE BEEN HIGHLIGHTED IN THE TORNADO WATCH AREA. LOOKING
AT CURRENT RADAR TRENDS...A QLCS LOOKS TO BE POSSIBLY DEVELOPING
ACROSS AUTAUGA AND WESTERN LOWNDES COUNTIES...AND WILL CLOSELY WATCH
THIS AS WELL AS IT MOVES INTO THE AREA OF GREATEST INSTABILITIES AND
SHEAR.

.AVIATION...
06Z TAF DISCUSSION.

CHAOTIC SKIES HAVE PLAGUED CENTRAL ALABAMA THE PAST 24 HOURS OR MORE
AND WILL CONTINUE FOR ANOTHER 24 HOURS OR SO. MULTIPLE CLOUD LAYERS
WITH MULTIPLE MECHANISMS AT WORK. SHOWERS AND A FEW THUNDERSTORMS
HAVE DEVELOPED AS THE WIND FIELDS ALOFT INCREASE WITH THE APPROACH
OF A SHORT WAVE OVER LOUISIANA. THE MORE ORGANIZED LOW LEVEL JET
WILL APPROACH FROM SOUTHERN MS AND SPREAD THE CHANCE OF THUNDER TO
ALL SITES. WENT PESSIMISTIC WITH CEILINGS AND TRIED TO PORTRAY THE
TRENDS. TRANSITION ALL SITES TO MVFR/IFR AND SHRA/TS 06-11Z. THIS
AREA OF ENHANCEMENT MOVES NORTHEAST WITH A DRY SLOT ON ITS HEELS.
INDICATED THIS BY RAISING CEILINGS A FEW HOURS BETWEEN 16-20Z.
ADDITIONAL SHRA/TS CHANCES ENTER WITH THE APPROACH OF THE COLD FRONT
LATE WEDNESDAY AFTERNOON BETWEEN 21-01Z. VIS SHOULD HOLD IN THE MVFR
RANGE OUTSIDE THE HEAVIEST RAIN ACTIVITY DUE TO WINDS. SOUTH WINDS
TRANSITION TO SOUTHWEST AFTER 20Z...FOLLOWED BY NORTHWEST AFTER 23Z.
THERE IS A SMALL CHANCE OF A SEVERE STORM WITH DAMAGING WIND GUSTS
AS ALL THIS ACTIVITY MOVES THROUGH. MVFR CEILINGS BEHIND THE FRONT
DO NOT CLEAR UNTIL AFTER 06Z AND MORE LIKELY AFTER 12Z.

&&

.PREV DISCUSSION... /ISSUED 331 AM CST WED NOV 16 2011/

SHOWERS ARE CURRENTLY MOVING ACROSS EAST CENTRAL ALABAMA OUT AHEAD
OF THE SURFACE FRONT. MEANWHILE...A BAND OF THUNDERSTORMS IS MAKING
ITS WAY INTO THE WESTERN PORTION OF THE CWA AT THE TIME OF THIS
WRITING. THE SHORTWAVE ASSOCIATED WITH THIS BAND OF PRECIP WILL
BECOME ABSORBED IN THE MAIN FRONTAL TROUGH LATER THIS
MORNING...INCREASING THE PRECIPITATION.

MAIN FOCUS TODAY WILL BE ON SEVERE WEATHER. LOOKING AT MESOSCALE
FEATURES...MODEL MU CAPE VALUES ARE CURRENTLY IN THE 300 TO 400 J/KG
RANGE...WITH LI VALUES JUST BELOW THE 0 MARK. THE 0-1 KM BULK SHEAR
IS AROUND 25 KTS AND 0-6 KM BULK SHEAR IS ABOVE 50 KITS. AS WE
PROGRESS FURTHER INTO THE MORNING...THE ATMOSPHERE WILL DESTABILIZE
AND WE WILL SEE MU CAPE VALUES ABOVE 1000 J/KM AND LI VALUES
DROPPING BELOW -2. LAPSE RATES ARE MORE IMPRESSIVE THAN PREVIOUS
THOUGHT. WITH ALL OF THAT SAID...THERE DOES APPEAR TO BE A MARGINAL
RISK FOR SEVERE THUNDERSTORMS THIS MORNING IN THE WESTERN PORTION OF
THE AREA...AND EXTENDING EASTWARD THROUGH THE AFTERNOON. WHILE THE
MAIN THREAT STILL APPEARS TO BE DAMAGING STRAIGHT LINE WINDS...THE
TORNADO THREAT HAS INCREASED AND WE CANNOT RULE OUT ISOLATED
TORNADOES IN THE AREA.

THE FRONT WILL PUSH THROUGH THE CWA THROUGHOUT THE DAY...AND LINGER
IN THE SOUTHEAST THIS EVENING BEFORE COMPLETELY CLEARING THE AREA BY
06Z THURSDAY. HAVE KEPT LIKELY POPS IN FOR THE SOUTHEAST COUNTIES
AFTER 00Z AND CHANCE POPS ELSEWHERE TO ACCOUNT FOR ANY SLOWING DOWN
OF THE FRONT. AS THE FRONT CLEARS...HIGH PRESSURE WILL MOVE BACK
INTO THE AREA. WINDS WILL SHIFT TO THE NORTH OVERNIGHT AND DRIER...
COLDER AIR WILL FILTER IN. FRIDAY MORNING LOOKS TO BE THE COLDEST
AREAWIDE...WITH TEMPERATURES FALLING CLOSE TO THE FREEZING MARK IN
MOST AREAS. WITH WINDS SHIFTING TO THE EAST ON FRIDAY...TEMPERATURES
WILL MODERATE BACK INTO THE MID TO UPPER 70S FOR THE WEEKEND.

A FRONT WILL APPROACH THE AREA AGAIN ON SUNDAY...HOWEVER THE HIGH
PRESSURE OVER THE AREA SHOULD KEEP THE BULK OF THE PRECIP TO THE
NORTH OF THE AREA. MODELS ARE NOT IN COMPLETE AGREEMENT AS TO THE
PROGRESSION OF THIS FEATURE...THEREFORE HAVE KEPT SLIGHT CHANCE POPS
IN FOR THE AREA SUNDAY THROUGH THE END OF THE FORECAST PERIOD TO
ACCOUNT FOR MODEL UNCERTAINTY AND ANY PRECIP THAT CAN MAKE IT DOWN
INTO THE AREA.
