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

Birmingham, AL (KBMX), launched 00:00Z, 4.7 hours before the alert went out and 50 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 Jul 17, 10:20 PM CDT, 1 hour 22 minutes earlier.

Area forecast discussion, Jul 17, 10:20 PM CDT, 1 hour 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1020 PM CDT WED JUL 17 2013

.UPDATE...
DISCUSSION.

&&

.DISCUSSION...

MODERATE INSTABILITY DEVELOPED OVER CENTRAL ALABAMA THIS AFTERNOON
WITH CAPE VALUES 3500-4000 AND LIS NEAR -10. DCAPE WAS IN THE 1200
RANGE. A FEW STORMS WERE ABLE TO GAIN SOME STRENGTH DURING THE MAX
HEATING DESPITE THE POOR LAPSE RATES. AS BOUNDARIES INTERACTED...
MORE STRONG STORMS POPPED UP. IN MOST INSTANCES...THE STORMS WERE
BELOW SEVERE LIMTS BUT DID PUT OUT FREQUENT TO CONTINUOUS
LIGHTNING...SOME HAIL AND GUSTY WINDS.

LATE THIS EVENING...NUMEROUS SMALL SCALE BOUNDARIES ARE ACROSS
CENTRAL ALABAMA. ONE WAS KICKING ACTIVITY OFF IN SOUTHERN TUSCALOOSA
COUNTY...A LARGE AREA ACROSS BARBOUR AND RUSSELL COUNTIES. ANOTHER
BOUNDARY FROM CONVECTION IN GEORGIA WAS AT THE ALABAMA STATE LINE
FROM I-85 NORTHWARD.

THEREFORE...EXPECT THE ACTIVITY TO LAST A BIT LONGER INTO THE
OVERNIGHT HOURS. THE MORE ORGANIZED AREA SOUTHEAST WILL GRADUALLY
DIMINISH BUT ADDITIONAL ISOLATED SHOWERS AND STORMS MAY POP UP
ANYTIME OR PLACE. WILL KEEP ISOLATED MENTION AFTER MIDNIGHT THROGUH
EARLY MORNING.

UPDATE ALREADY OUT WITH ANOTHER TO FOLLOW SHORTLY.

75

&&

.AVIATION...
00Z TAF DISCUSSION.

HAVE ALREADY HAD TO MAKE A EARLY AMENDMENT FOR AN OUTFLOW BOUNDARY
AND BATCH OF THUNDERSTORMS HEADING FOR KEET. ASIDE FROM THAT...I
THINK THE TREND WILL BE FOR STORMS TO DECREASE IN COVERAGE THROUGH
THE NEXT 2-3 HOURS LEAVING PREDOMINANTLY VFR CONDITIONS OVERNIGHT.
WE STILL SEEM TO BE IN A TROPICAL ATLANTIC AIR MASS...WHICH
TYPICALLY MEANS LESS CHANCE FOR OVERNIGHT HAZE OR SMOG/FOG. I THINK
CONDITIONS WILL REMAIN VFR THROUGH THE MAJORITY OF THE DAY FOR THE
MAJORITY OF TERMINALS ON THURSDAY. CONFIDENCE IN COVERAGE AND
PLACEMENT OF AFTERNOON HEATING DRIVEN THUNDERSTORMS IS STILL LOW
ENOUGH TO PRECLUDE THEIR INCLUSION IN THIS SET OF TAFS.

/61/

&&

.PREV DISCUSSION..../ISSUED AT 317 PM CDT WED JUL 17 2013/

THE UPPER RIDGE OVER THE OHIO VALLEY APPEARS TO BE SLOWLY RELAXING
ITS GRIP AND WITH CONVECTION PREVALENT THIS AFTERNOON OVER THE
SOUTHERN APPALACHIANS AND CAROLINAS. THE STORMS OVER GEORGIA DO
NOT APPEAR TO BE MOVING WITH THE MEAN-LAYER FLOW WHICH WOULD BE
TO THE WEST-SOUTHWEST. SINCE THE STORM MOTION IS IN A VERY SLOW
SOUTHERLY DIRECTION...CONFIDENCE IS RATHER LOW ON WHETHER THIS
ACTIVITY WILL MAKE WESTWARD PROGRESS AND AFFECT EAST ALABAMA THIS
EVENING. HAVE GONE WITH 30 POPS FOR THE EVENING HOURS IN CASE
OTHER SHOWERS AND STORMS DEVELOP IN OUR CWA.

RAIN CHANCES WILL BE INCREASING FOR THURSDAY AND INTO THE WEEKEND
AS THE RIDGE ERODES AND BECOMES REPLACED BY A BROAD UPPER-LEVEL
TROUGH. THE COOLER MID-LEVEL TEMPS WITH THIS PATTERN SHOULD LEAD
TO SCATTERED OR EVEN WIDESPREAD SHOWERS AND THUNDERSTORMS EACH AND
EVERY DAY THROUGH THE END OF THE FORECAST PERIOD. HIGH TEMPS ARE
EXPECTED TO BE SLIGHTLY BELOW NORMAL WITH ENHANCED CLOUD COVER AND
ABUNDANT GROUND MOISTURE IN PLACE.

87/GRANTHAM

.BMX WATCHES/WARNINGS/ADVISORIES...
