The radar

The Maxwell AFB radar (KMXX), 109 km from the middle of the area, began a volume at 22:53 UTC, the scan nearest the moment this went out.

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 12:00Z, 10.8 hours before the alert went out and 122 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.

Area forecast discussion, Aug 8, 2:42 PM CDT, 3 hours 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
242 PM CDT SAT AUG 8 2015

.DISCUSSION...

MEAN MOISTURE IS LIMITED THIS AFTERNOON TO THE SOUTHWESTERN HALF
OF THE AREA...AND MENTIONED 15-30 POPS HERE THROUGH 7 PM. MOST OF
THE ACTIVITY CLOSER TO THE COAST. A QUASI-STATIONARY FRONT
REMAINS OVER CENTRAL ALABAMA WITH SLIGHTLY LESS HEAT IN THE NORTH.

MODELS ARE IN GOOD AGREEMENT THAT THE UPPER RIDGE STRENGTHENS AND
EXPANDS EASTWARD SUNDAY AND MONDAY. LOW LEVEL THICKNESS VALUES AND
850 TEMPS INCREASE ACCORDINGLY. THEREFORE...TEMPERATURES SHOULD
TOP OUT CLOSE TO THE CENTURY MARK WEST BOTH DAYS...A TAD LESS HOT
EAST. SURFACE DEW POINTS WILL REMAIN IN THE 70S SUNDAY AND
MONDAY...WHICH WILL PUT THE HEAT INDICES INTO THE 105 TO 109
DEGREE RANGE. WENT AHEAD AND EXPANDED THE HEAT ADVISORY INTO
MONDAY EVENING. WE WILL MONITOR THIS PERIOD CLOSELY AS A FEW AREAS
IN THE WEST WILL APPROACH WARNING CRITERIA OF 110 DEGREES OR
GREATER.

MODELS CONTINUE THEIR AGREEMENT AS THE SYNOPTIC PATTERN CHANGES
SLIGHTLY. AN UPPER DISTURBANCE ROTATES ACROSS THE GREAT LAKES AND
BEGINS CARVING OUT AN UPPER TROUGH FOR THE FAR EASTERN CONUS. THIS
WILL ALLOW A COLD FRONT TO PUSH THROUGH THE AREA TUESDAY.
INSTABILITY IS RATHER HIGH AHEAD IF THIS FRONT BUT WILL HAVE TO
WATCH THE INFLUENCES OF THE UPPER RIDGE AND WARMER TEMPS ALOFT. A
FEW STRONG STORMS MAY BECOME POSSIBLE MONDAY AFTERNOON THROUGH
TUESDAY. DID ADD A THREAT TO THE HWO JUST YET...BUT WILL HAVE TO
KEEP AN EYE OUT AS MODELS ARE HINTING AT UPWARD MOTION BUT LIMITED
ORGANIZATION.

WEDNESDAY THROUGH SATURDAY WILL BE MUCH CLOSER TO NORMAL
TEMPERATURES AND LESSER HUMIDITY. THE UPPER TROUGH SHOULD REMAIN
IN THE VICINITY AND HAVE EVEN ADDED SMALL POPS AS THE PATTERN MAY
EVEN RETROGRADE FURTHER.

.AVIATION...
18Z TAF DISCUSSION.

VFR CONDITIONS WILL PREVAIL THIS AFTERNOON WITH A CU FIELD BETWEEN
3 AND 7K FEET. SCATTERED SHOWERS AND STORMS ARE EXPECTED TO
DEVELOP GENERALLY ACROSS SOUTHERN PORTIONS OF THE STATE...WITH
LESS COVERAGE ELSEWHERE. DUE TO THE LOWER COVERAGE...HAVE NOT
INCLUDED ANY MENTION OF VCTS IN THE TAFS AT THIS TIME. PREVAILING
SURFACE WINDS WILL REMAIN LIGHT AND PERHAPS VARIABLE FROM
NORTHWEST TO WESTERLY THROUGH THE AFTERNOON. LIGHT MVFR FOG WILL
BE POSSIBLE ONCE AGAIN OVERNIGHT TONIGHT...BUT NO MAJOR IMPACTS
ARE EXPECTED.

.FIRE WEATHER...

ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE IN THE AREA
ROUGHLY FROM HAMILTON DOWN TO SELMA. VERY HOT CONDITIONS SUNDAY
