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, 9.1 hours before the alert went out and 83 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, Jul 4, 3:06 PM CDT, 1 hour before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
306 PM CDT MON JUL 4 2011

.DISCUSSION...

SCATTERED TO NUMEROUS THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
AS A GENERAL WEAKNESS IN THE UPPER ATMOSPHERE HAS SET IN ACROSS
THE DEEP SOUTH. STRONG TO ISOLATED SEVERE STORMS WITH WIND GUSTS
REPORTED UP TO 70 MPH WITH SOME DAMAGE HAVE OCCURRED THUS FAR.
THUNDERSTORMS USUALLY CONTINUE INTO THE EARLY EVENING HOURS WITH
THIS TYPE OF PATTERN SO WILL KEEP THE CHANCE WORDING FOR THE
OVERNIGHT AND LET THE EVENING SHIFT CLEAN IT UP ONCE THE ACTIVITY
DIES DOWN. WAS TEMPTED TO GO WITH LIKELY POPS THE NEXT COUPLE OF
DAYS AS LEFT OVER BOUNDARIES...DAYTIME HEATING AND THE PRESENCE
OF THE UPPER TROUGH SHOULD ALLOW FOR PLENTY OF THUNDERSTORM
DEVELOPMENT...BUT WILL HOLD OFF WITH HIGHER CHANCE WORDING FOR
NOW.

THIS PATTERN IS EXPECTED TO REMAIN IN PLACE THROUGH FRIDAY AT
WHICH POINT SOME UPPER RIDGING WILL BEGIN TO BUILD NEAR THE OHIO
VALLEY AND LESSEN THE POTENTIAL FOR CONVECTION ALTHOUGH NOT
ELIMINATE EITHER. WILL TAPPER THE POPS TO LOWER CHANCE AS WE REACH
INTO THE WEEKEND AND EARLY NEXT WEEK WHEN CONVECTION LOOKS TO
BECOME MORE DIURNALLY RESTRICTED.

TEMPERATURES NEAR NORMAL FOR EARLY JULY WITH HIGHS IN THE LOWER TO
MID 90S AND LOWS IN THE UPPER 60S TO LOWER 70S.

&&

.AVIATION...18Z TAF DISCUSSION.

SEVERAL OUTFLOW BOUNDARIES APPROACHING THE AREA COULD SPARK SOME
AFTERNOON THUNDERSTORMS. WITH HIGH PRESSURE NO LONGER DOMINATING THE
WEATHER PATTERN...THERE SHOULD BE NO SUPPRESSION OF CONVECTION. WENT
AHEAD AND MENTIONED VCTS AT ALL SITES SINCE CONFIDENCE IS NOT HIGH
AS TO WHERE EXACTLY THUNDERSTORMS WILL INITIATE AND PROPAGATE
THROUGHOUT THE DAY. AMENDMENTS MAY BE NECESSARY THIS AFTERNOON ONCE
CONVECTION BEGINS. WINDS WILL BECOME CALM ONCE AGAIN AFTER SUNSET
AND THE THUNDERSTORM ACTIVITY CLEARS. LOW CLOUDS WILL LIKELY MOVE
INTO THE NORTHERN 4 SITES DURING THE MORNING HOURS. DOES NOT LOOK
LIKE CLOUDS WILL MAKE IT AS FAR SOUTH AS MGM OR TOI...SO WITH
ABUNDANT MOISTURE AGAIN...EXPECT BR FOR A COUPLE OF HOURS TOMORROW
MORNING.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO
THE END OF THE FORECAST UNTIL FURTHER NOTICE. THE CEILOMETER DATA
WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY.
