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.

Area forecast discussion, May 17, 7:01 PM CDT, 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
701 PM CDT FRI MAY 17 2013

.UPDATE...
FOR 00Z AVIATION.

&&

.DISCUSSION...

UPPER LEVEL TROUGH WILL CONTINUE ITS SLOW EASTWARD PROGRESSION
THROUGH THE NIGHT. FOR THE REMAINDER OF THE AFTERNOON AND EARLY
EVENING...THE AREA OF SHOWERS AND ISOLATED EMBEDDED THUNDERSTORMS
OVER NORTHERN ALABAMA WILL PRODUCE STEADY RAINFALL WITH MORE
ISOLATED TO SCATTERED CONVECTION BEGINNING TO FILL IN AROUND
SOUTHWEST ALABAMA. SUFFICIENT INSTABILITY AND SHEAR REMAIN
SUPPORTIVE OF AN ISOLATED STRONG TO SEVERE THREAT THROUGH THE
EARLY EVENING...OR THE REMAINDER OF THE PEAK HEATING PERIOD.

TONIGHT...WEAKENING INTENSITY BUT SOME DECENT COVERAGE STILL
EXPECTED ACROSS THE NORTHERN HALF OF THE CWA. A SIMILAR SET UP FOR
SATURDAY AND SATURDAY NIGHT...ALTHOUGH THE BETTER COVERAGE WILL
SLIDE INTO EASTERN ALABAMA AS THE UPPER TROUGH SHIFTS FARTHER
EASTWARD.

A FEW SHOWERS POSSIBLE IN EAST ALABAMA ON SUNDAY WITH DRY WEATHER
AREA WIDE SUNDAY THROUGH TUESDAY AS AN UPPER RIDGE BUILDS IN.
ANOTHER SYNOPTIC SYSTEM MOVES INTO THE AREA MID TO LATE WEEK WITH
INCREASING DIURNAL SHOWERS AND THUNDERSTORMS.

TEMPERATURES WILL REMAIN COOL IN THE RAIN SHIELD AREA TOMORROW AND
SUNDAY WITH WARMER HIGHS NEXT WEEK.

.AVIATION...
00Z TAF DISCUSSION.

WIDESPREAD SHOWERS AND STORMS HAVE SPREAD OVER MUCH OF CENTRAL
ALABAMA LATE THIS AFTERNOON AHEAD OF A LARGE OUTFLOW BOUNDARY.
TSRA WAS ADDED TO THE SHORT TERM FOR KEET AND KBHM AS THE BOUNDARY
MOVES THROUGH WITH A TEMPORARY WIND SHIFT TO THE NORTHWEST
FOLLOWING THE PASSAGE OF THE BOUNDARY. THE BOUNDARY HAS GONE
THROUGH KTCL...AND THE MAJORITY OF THE TSRA HAS MOVED THROUGH.
HOWEVER...A FEW SHOWERS WILL REMAIN POSSIBLE THROUGH THE EVENING.
FOR KANB...GENERALLY RAIN WILL BE EXPECTED WITH A FEW EMBEDDED
THUNDERSTORMS AND HAVE OPTED TO GO WITH VCTS FOR THAT LOCATION
THROUGH 03Z. THE SOUTHERN LOCATIONS OF KMGM AND KTOI WILL HAVE
LESS OF A CHANCE OF TSRA DEVELOPMENT WITH THE LOSS OF DAYTIME
HEATING...BUT HAVE GONE WITH VCTS FOR THE EARLY EVENING HOURS AT
KMGM AND NO MENTION OF VCTS OR TSRA FOR KTOI AT THIS TIME.

FOR THE REMAINDER OF THE OVERNIGHT HOURS...MVFR CIGS WILL REMAIN
POSSIBLE WITH MOST SHOWERS AND STORMS EXPECTED TO DISSIPATE.
