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 NATIONAL WEATHER SERVICE BIRMINGHAM AL 337 PM CDT SUN AUG 21 2005 .SHORT TERM (TONIGHT THROUGH TUESDAY)... BOUNDARY LAYER INCREASED MOISTURE IS EVIDENT ON LATEST VISIBLE SATELLITE IMAGES OUT AHEAD OF A SURFACE COLD FRONT. THE FRONT WAS ADVERTISED TO BLAZE ON THROUGH THE AREA IN THE MIDDLE OF THE SUMMER. WELL SHORT TERM MODEL SOLUTIONS HAVE FINALLY COME AROUND AND MADE THE PROGRESSION OF THE FRONT MUCH SLOWER. MOISTURE POOL WILL GRADUAL MOVE SOUTHWARD THROUGH TUESDAY PROVIDING FOCUS FOR MAINLY AFTERNOON CONVECTION. TEMPERATURES WILL BE QUITE WARM AGAIN TOMORROW ESPECIALLY SOUTH. SO WITH TEMPS IN THE MID 90S AND DEW POINTS IN THE MID 70S...EXTENDED THE HEAT ADVISORY ONE MORE DAY GENERALLY FOR AREAS ALONG AND SOUTH OF AN I-85/US 80 LINE. ALTHOUGH NOT ALL OF THE SURFACE OBS SUPPORT 110 DEGREE HEAT INDICES...REVIEWING OTHER LOCAL OBSERVATIONS ONLY STRENGTHENS THE IDEA THAT VARIABILITY EXISTS...HIGHER AND LOWER. HEAT INDICES AROUND 110 LOOKS GOOD AS CONDITIONS REMAIN HOT. .LONG TERM (WEDNESDAY THROUGH SUNDAY)... MEDIUM RANGE MODELS IN FAIRLY GOOD AGREEMENT THIS TIME OUT. TYPICAL STORM TRACK FOR THIS TIME OF YEAR KEEPS THE UPPER LEVEL SYSTEMS ROLLING THROUGH SOUTHERN CANADA WITH A BROAD SUBTROPICAL RIDGE FROM THE PACIFIC TO THE ATLANTIC. IT LOOKS AS IF THE STRENGTH OF THE RIDGE OVERHEAD WILL WEAKEN A BIT WITH TIME AS 500 MB HEIGHTS FALL TO AROUND 590DM. MAIN QUANDARY HERE IS WHERE THE CLOSED ANTICYCLONE SITS AND DOES IT WEAKEN. DIFFUSE SURFACE BOUNDARY THAT PLAGUES THE SHORT TERM REMAINS LURKING AROUND INTO THE EXTENDED TIME FRAME. MODELS HAVE HAD THE TREND OF PUSHING THE FRONT RIGHT THROUGH THE FORECAST AREA FOR SEVERAL RUNS LAST WEEK...BUT AS OF LATE...A BIG SLOW DOWN IN THE THINKING...IT IS SUMMER? AT THIS TIME...WILL GO WITH THE SOLUTION THAT FRONT SAGS SOUTHWARD VERY SLOWLY AND FINALLY STARTS DISSIPATING OVER FAR SOUTHERN ALABAMA ON THURSDAY AND FRIDAY. SURFACE HIGH BUILDS DOWN FROM THE NORTHEAST BY NEXT WEEKEND...AND FINALLY THE DRIER AIR ARRIVES. KEEP YOUR FINGERS CROSSED UNLESS YOU LIKE THE SAUNA. WITH SURFACE BOUNDARY IN THE FORECAST AREA ACTING AS A FOCUS FOR CONVECTION...WILL INCREASE POPS SLIGHTLY WEDNESDAY AND THURSDAY. THE TREND OF MOVING THE BEST RAIN CHANCES SOUTHWARD WITH TIME REMAINS. MEX MOS SEEMS REASONABLE AND WOULD EXPECT CLOSER TO CLIMATE TEMPS. && .PRELIMINARY POINT TEMPS/POPS...
