What forecasters said that day

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.

NWS Birmingham, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at May 20, 3:30 PM CDT, 2 hours 13 minutes earlier.

Area forecast discussion, May 20, 3:30 PM CDT, 2 hours 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
330 PM CDT SUN MAY 20 2012

.DISCUSSION...

CURRENT WATER VAPOR IMAGERY INDICATES A TROUGH OVER THE UPPER
MISSISSIPPI RIVER VALLEY WITH RIDGING OVER NEW ENGLAND AND TROPICAL
STORM ALBERTO SPINNING OFF THE SOUTH CAROLINA COAST. AT THE
SURFACE...A COLD FRONT STRETCHES FROM WISCONSIN DOWN INTO CENTRAL
TEXAS. CLOSER TO HOME...DAYTIME HEATING AND WEAK SHORTWAVES THAT
HAVE BEEN ROTATING THROUGH THE AREA HAVE LEAD TO WIDESPREAD CU AND A
FEW ISOLATED SHOWERS ACROSS AREAS WEST OF I-65 AND NORTH OF I-20
WHERE DEWPOINTS ARE IN THE LOW TO MID 60S. THIS ACTIVITY SHOULD
DIMINISH AFTER SUNSET.

LATE TONIGHT/EARLY MONDAY MORNING SHOWERS THAT ARE EXPECTED TO
DEVELOP AHEAD OF THE COLD FRONT CURRENTLY OVER THE CENTRAL U.S. WILL
BEGIN TO NUDGE INTO NORTHWESTERN PORTIONS OF THE FORECAST AREA. A
WEAK UPPER LEVEL TROUGH...COLD FRONT AND PW VALUES APPROACHING 1.5
INCHES WILL MAKE FOR SCATTERED SHOWERS AND THUNDERSTORMS TO START TO
THE WORK WEEK. MODELS ARE INDICATING SBCAPE VALUES AROUND 1500 J/KG
MONDAY AFTERNOON AS THE UPPER LEVEL TROUGH PROVIDES WEAK DIFFLUENT
FLOW ALOFT. HOWEVER...DEEP LAYER 0-6 KM SHEAR WILL BE RATHER
WEAK...NORTHWESTERLY FLOW SHOULD KEEP THE LOW LEVELS RATHER DRY AND
MID-LEVEL LAPSE RATES WILL BE NEAR MOIST ADIABATIC. APPEARS THERE
WILL BE TO MANY LIMITING FACTORS FOR WIDESPREAD STRONG STORMS BUT
CAN NOT RULE OUT AN ISOLATED STRONG STORM MONDAY AFTERNOON. CHANCES
FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS EASTERN PORTIONS
OF THE STATE INTO THE DAY TUESDAY AS THE FRONT PROGRESSES THROUGH
THE FORECAST AREA.

FOR THE MIDDLE PART OF NEXT WEEK....SOUTHERLY FLOW WILL RETURN
ACROSS THE SOUTHEAST AS AN UPPER LEVEL TROUGH STRENGTHENS OVER THE
WESTERN CONUS. BOTH THE GFS AND ECMWF ARE BOTH IN AGREEMENT WITH THE
SYNOPTIC PATTERN LATE NEXT WEEK INTO NEXT WEEKEND WITH A HIGHLY
AMPLIFIED TROUGH OVER THE WESTERN CONUS AND A HIGHLY AMPLIFIED RIDGE
OVER THE EASTERN CONUS. THIS MEANS MUCH WARMER AND DRIER CONDITIONS
FOR THE FORECAST AREA LATE NEXT WEEK INTO NEXT WEEKEND. TEMPERATURES
ACROSS CENTRAL ALABAMA COULD REACH UP INTO THE MID 90S DURING THIS
TIME PERIOD.

MA

&&

.AVIATION...

NO SIGNIFICANT AVIATION CONCERNS AT THIS TIME. LOOKING FOR SOME
CUMULUS CLOUDS TO CONTINUE TO DEVELOP BETWEEN 4K AND 6K THROUGH
THE AFTERNOON. THERE IS AN ISOLATED CHANCE OF A SHOWER OR
THUNDERSTORM THIS AFTERNOON. BY TOMORROW MORNING...AN UPPER LEVEL
TROUGH WILL APPROACH THE DEEP SOUTH AND SCATTERED SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO DEVELOP IN NORTHWEST ALABAMA BY MID
TO LATE MORNING AND POSSIBLY PUSHING INTO THE TCL...BHM AND ANB
VICINITY TOWARDS THE END OF THE FORECAST PERIOD. WINDS LIGHT
THROUGHOUT THE PERIOD AND EASTERLY TO NORTHEASTERLY THROUGH THE
REMAINDER OF THE AFTERNOON AND EARLY EVENING.
