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, 10.0 hours before the alert went out and 118 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.

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 28, 3:06 PM CDT, 1 hour 53 minutes earlier.
Area forecast discussion, Jul 28, 3:06 PM CDT, 1 hour 53 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 306 PM CDT TUE JUL 28 2009 .DISCUSSION...SHORT WAVE TROF OVER ARKANSAS CONTINUES TO PLOD EASTWARD AND WILL BRING NUMEROUS SHOWERS AND THUNDERSTORMS TO CENTRAL ALABAMA THROUGH THE EVENING HOURS. THUNDERSTORMS HAVE BEEN CONFINED TO AREAS ACROSS SOUTH ALABAMA WHERE LESS CLOUD COVER HAS ALLOWED FOR MORE HEATING AND INSTABILITY. A NEW LINE OF STORMS HAS DEVELOPED FROM TUPELO TO JACKSON MISSISSIPPI. THERE HAS BEEN ENOUGH CLEARING ACROSS EAST MISSISSIPPI TO ALLOW TEMPERATURES TO CLIMB INTO THE MIDDLE AND UPPER 80S...AND SURFACE BASED CAPE VALUES ARE 2500-3000 J/KG. THERE IS STILL POTENTIAL FOR SEVERE THUNDERSTORMS THROUGH THE EARLY EVENING HOURS...MAINLY WEST OF I-65. FORECAST WILL CONTINUE WITH LIKELY POPS OVERNIGHT AS SHORT WAVE TROF APPROACHES THE AREA. EVEN THOUGH PRIMARY SHORT WAVE TROF WILL PUSH EAST OF AREA BY WEDNESDAY MORNING...A MID LEVEL INSTABILITY WILL REMAIN ACROSS THE AREA WITH PRECIPITABLE WATER VALUES HOLDING NEAR 2 INCHES. EXPECT NUMEROUS SHOWERS AND THUNDERSTORMS ONCE AGAIN ON WEDNESDAY...BUT WITH LESS UPPER LEVEL SUPPORT...STORMS SHOULD STAY BELOW SEVERE LIMITS. ANOTHER SIGNIFICANT SHORT WAVE TROF WILL DROP INTO THE PLAINS STATES WEDNESDAY NIGHT. BOTH NAM AND GFS MODELS KEEP STRONGER AND MORE ORGANIZED CONVECTION TO THE NORTHWEST OF ALABAMA WEDNESDAY NIGHT AND THURSDAY...EVEN THOUGH GFS DOES BRING A BULLSEYE OF RAINFALL ACROSS EXTREME NORTH ALABAMA LATE WEDNESDAY NIGHT...BUT THIS SEEMS A LITTLE TO FAR REMOVED FROM ADVANCING SHORT WAVE TROF. THURSDAY NIGHT AND FRIDAY COULD BE ACTIVE ACROSS AREA AS BOTH MODELS SHOW A SURFACE FRONT MOVING INTO NORTHWEST ALABAMA ON FRIDAY. THE SURFACE BOUNDARY STALLS OUT ACROSS CENTRAL ALABAMA BY SATURDAY...SO THERE MAY BE A DECREASE IN RAIN CHANCES NORTH OF I-20...BUT CHANCES OF RAIN WILL STAY IN THE FORECAST THROUGH THE FIRST PART OF NEXT WEEK. 58/ROSE && .AVIATION...18Z TAF DISCUSSION. SCATTERED SHOWERS WILL PLAGUE CENTRAL ALABAMA THIS AFTERNOON...AHEAD OF A MUCH LARGER SHIELD OF RAIN AND THUNDER. THESE WILL LIKELY LAST THROUGH THE OVERNIGHT HOURS...AND INTO THE MORNING...DISSIPATING FROM WEST TO EAST ON WEDNESDAY. FOR NOW...HAVE PUT A PREVAILING MVFR AT ALL SITES THIS AFTERNOON...BUT THERE WILL BE CHANCE FOR AN AMENDMENT LATER THIS AFTERNOON AS THE MAIN SHIELD OF RAIN MOVES INTO THE AREA. THERE IS A THREAT OF STRONG GUSTY WINDS TOO...SO WILL HAVE TO WATCH THE UPSTREAM OBS AS THESE STORMS MOVE THROUGH THE AREA. KEET CEILOMETER IS STILL OUT OF COMMISSION...WAITING FOR THE DELIVERY OF A PART. SHOULD BE BACK UP THIS EVENING OR TOMORROW AT THE LATEST...DEPENDING ON WHEN THE SHOWERS MOVE OUT OF THE AREA. && .PRELIMINARY POINT TEMPS/POPS...
