The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

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

Peachtre/Fal Fld, GA (KFFC), launched 12:00Z, 9.6 hours before the alert went out and 169 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 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 14, 4:07 PM CDT, 27 minutes earlier.

Area forecast discussion, May 14, 4:07 PM CDT, 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
407 PM CDT WED MAY 14 2014

.DISCUSSION...

LARGE AREA OF RAIN AND EMBEDDED THUNDERSTORMS AHEAD OF THE FRONT
HAS KEPT US FROM HEATING UP AS MUCH TODAY AND HAS ALSO KEPT SOME
OF THE INSTABILITY DOWN. A THIN LINE OF THUNDERSTORMS ALONG THE
FRONT ARE CURRENTLY APPROACHING IN THE WEST NEAR THE MS/AL STATE
LINE. SOME VERY SMALL CIRCULATIONS IN THE EMBEDDED TSTORMS HAVE
POPPED UP REGARDLESS IN A COUPLE OF INSTANCES...BUT FOR THE MOST
PART OUR SEVERE POTENTIAL HAS BEEN LIMITED FOR THIS AFTERNOON
ACROSS MOST OF THE AREA. THAT POTENTIAL DOES NOT GET ANY BETTER
DURING THE OVERNIGHT HOURS AS THE MAIN ENERGY REMAINS TO THE NORTH
OF CENTRAL ALABAMA. THE FRONT SHOULD PROGRESS ACROSS THE FAR
WESTERN COUNTIES OF CENTRAL ALABAMA DURING THE EVENING AND
OVERNIGHT HOURS...WITH WEST 2/3 MAINLY IN THE CLEAR BY THURSDAY
MORNING SUNRISE. THE FRONT SHOULD EXIT BY MIDDAY THURSDAY WITH
MUCH COOLER AND IMPROVING CONDITIONS. HOWEVER...SOME WRAP AROUND
MOISTURE AND CLOUD COVER ARE EXPECTED BEHIND THE FRONT THURSDAY
NIGHT INTO FRIDAY.

THE RIDGE SETS IN FOR THE LATTER PART OF THE WEEK ACROSS THE C
U.S. AND BELOW NORMAL TEMPERATURES ARE IN STORE WITH NORTHERLY
FLOW FOR THE LATTER PART OF THE WEEK. A SHOWER OR TWO WILL BE
POSSIBLE ACROSS THE FAR NORTH ON FRI/SUN AS THE UPPER TROUGH TAKES
ITS TIME TO MOVE EASTWARD. OTHERWISE...LOOK FOR A A SLOWLY
MODERATING AIR MASS BY THE LATTER PART OF THE WEEKEND INTO THE
BEGINNING OF NEXT WEEK AS THE LOW LEVEL FLOW FROM THE NORTH ENDS
AS THE RIDGE MOVES INTO THE EASTERN U.S.

08/MK

&&

.AVIATION...
18Z TAF DISCUSSION.

VARYING INTENSITIES OF RAIN AND THUNDERSTORMS AROUND THE AREA
TODAY WILL CREATE A LARGE VARIETY OF CEILING AND VISIBILITY
CONDITIONS ALONG WITH IT. BASED ON THE LATEST RADAR LOOPS...IT
LOOKS LIKE THE MAIN MODERATE TO HEAVY RAIN CORRIDOR WILL BE
ORIENTED NORTH TO SOUTH RIGHT UP THE MIDDLE OF THE STATE...WITH
THE HIGHEST IMPACTS COMING TO BHM...EET...AND MGM. HAVING SAID
THAT...THE RAIN IS LIKELY TO FILL IN AND SPREAD INTO OTHER AREAS
AS WELL. THE MAIN GIST OF THE FORECAST IS FOR SEVERAL HOURS OF
STEADY RAIN AND OCCASIONAL LOWERED CONDITIONS IN THUNDERSTORMS.
THE THUNDERSTORM/HEAVY RAIN CHANCES SHOULD LET UP AROUND SUNSET...
BUT THERE'S BOUND TO BE AREAS (OR ONE LARGE AREA) OF LIGHT RAIN
CONTINUING FOR SEVERAL MORE HOURS AFTER THAT. COLD FRONT PASSAGE
WILL BE MARKED BY A WIND SHIFT OUT OF THE WEST AND NORTHWEST...
FOLLOWED BY LOW MVFR OR IFR CONDITIONS THROUGH THE OVERNIGHT
HOURS.
