Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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, 5.0 hours before the alert went out and 37 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...UPDATE NATIONAL WEATHER SERVICE BIRMINGHAM AL 1108 AM CDT FRI SEP 14 2007 .UPDATE.... THE REMNANTS OF HUMBERTO CONTINUE TO MOVE ACROSS THE AREA...WITH AN EXPANSIVE AREA OF MODERATE RAIN ACROSS THE TENNESSEE VALLEY...AND SEVERAL BANDS OF MODERATE TO HEAVY RAIN MOVING EASTWARD ACROSS CENTRAL ALABAMA. THE SURFACE LOW CIRCULATION IS CURRENTLY LOCATED ALONG THE CENTRAL MISSISSIPPI/ALABAMA STATE LINE. AS THIS CIRCULATION CONTINUES TO MOVE EASTWARD...AIDED BY DAYTIME HEATING AND THE UPPER LEVEL TROUGH TRAVERSING THE REGION...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON...PRIMARILY SOUTH OF INTERSTATE 20...AND AHEAD OF THE CURRENT RAIN BANDS. SHOWERS AND ISOLATED THUNDERSTORM ACTIVITY WILL COME TO AN END FROM WEST TO EAST ACROSS THE STATE...WITH THE MAJORITY OF THE ACTIVITY IN THE FAR NORTHWEST COMING TO AN END BY NOON. LINGERING LIGHT SHOWERS OR DRIZZLE WILL REMAIN POSSIBLE THROUGH THE AFTERNOON AS LOW LEVEL MOISTURE WRAPS ABOUT THE BACK SIDE OF THE SURFACE LOW. RAIN SHOULD COME TO AN END ACROSS THE CENTRAL PART OF THE STATE BY EARLY EVENING...AND SHOULD EXIT THE EASTERN COUNTIES BY LATE EVENING. FOR THE MORNING UPDATE...WILL EDIT THE POP AND WX GRIDS TO REFLECT THE RAIN COMING TO AN END IN THE FAR NORTHWEST FOR THE AFTERNOON. ALSO WILL BUMP MAX TEMPERATURES UP A COUPLE DEGREES IN THE SOUTHEAST...AS THEY HAVE WARMED UNDER CLEAR SKIES. UPDATED ZONES WILL BE OUT SOON. 14 && .PREV DISCUSSION.... .LONG TERM... SATURDAY THROUGH SUNDAY NIGHT...THE LATEST MODEL SUITE ON THE WHOLE HAS SPED THINGS UP A BIT AT THE BEGINNING OF THE PERIOD. GFS/WRF/ NGM/CAN GLOB/SREF ALL HAVE THE UPPER LEVEL LONG WAVE TROUGH AXIS EXITING STAGE RIGHT BY 12Z. THEREFORE...THE SURFACE COLD FRONT AND ANY REMAINING TROPICAL MOISTURE SHOULD BE PUSHED SOUTH AND EAST OF THE AREA. INTERESTINGLY ENOUGH...THE WRF STILL TRIES TO HOLD BACK ENOUGH MOISTURE TO PRODUCE A FEW SHOWERS SOUTH OF I-85 WITH ITS DEVELOPMENT OF ANOTHER LOW IN THE NORTHERN GULF. WILL CONTINUE LEANING TOWARD THE GFS AS IT APPEARS IT IS HANDLING THE CURRENT SITUATION A BIT BETTER. MODELS INDICATE A SHORT WAVE TROUGH DIVING DOWN FROM THE NORTH SUNDAY NIGHT. AT THIS TIME...I THINK THE MOISTURE WILL BE TOO LIMITED. WILL NOT MENTION ANY RAIN CHANCES SATURDAY OR SUNDAY AT THIS TIME. MAV/MET MOS STILL HAVE THEIR DIFFERENCES IN THE LOW TEMPS. MAV ADVERTISING MUCH COOLER AS DRY AIR HAS A BIGGER PUSH. WILL CONTINUE THE TREND OF LEANING TOWARD THE MAV MOS WITH THE COOLEST MORNING ON SUNDAY. HIGHS MUCH CLOSER TO NORMAL FROM THE UPPER 70S TO MID 80S AREAWIDE. MONDAY THROUGH THURSDAY...MEDIUM RANGE MODELS START OFF IN FAIR AGREEMENT. SHORT WAVE SUNDAY NIGHT EVENTUALLY FORMS AN UPPER LOW ALONG THE SOUTHEAST COAST WITH THE HIGH BUILDING OVER OUR AREA. THIS LOW THEN RETROGRADES AND UNDERCUTS THE HIGH. AT THE SURFACE... RIDGING ALONG THE APPALACHIANS LOOKS TO HOLD MUCH OF THE PERIOD. MOISTURE REMAINS SPARSE UNTIL THE TAIL END OF THE PERIOD WHEN EASTERLY FLOW USHERS IN ATLANTIC MOISTURE. WILL ADD 15-25 POP FOR THE THU TIME FRAME. WILL ACCEPT THE ENSEMBLE AVERAGES FOR TEMPS AT THIS TIME. 75/LINHARES && .AVIATION...06Z TAF DISCUSSION. OCCASIONAL LIGHT TO MODERATE RAIN WILL OCCUR THROUGH THE TAF PERIOD...PRIMARILY ACROSS THE NORTHERN HALF OF ALABAMA AS THE RAIN SHIELD WITH THE REMNANTS OF HUMBERTO LIFT OFF TO THE NORTHEAST AND EAST.
