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, Jul 19, 2:47 AM CDT, 11 hours 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 247 AM CDT SAT JUL 19 2003 A NORTHERLY FLOW CONTINUES ALOFT WITH A MCS MOVING SOUTH THROUGH MS VALLEY THIS MORNING. MOST OF THE THUNDERSTORMS IN THIS COMPLEX SHOULD REMAIN TO THE WEST OF AL. HOWEVER, WITH A SURFACE BOUNDARY AND POSSIBLY OTHER OUTFLOW BOUNDARIES MOVING INTO THE REGION, SCATTERED THUNDERSTORM FORECAST STILL LOOKS GOOD. 00Z BMX SOUNDING SHOWS A CAP AT 700MB AND THIS COULD SLOW THUNDERSTORM DEVELOPMENT SOME, BUT INSTABILITY AND BOUNDARYS SHOULD BE ENOUGH TO BREAK THE CAP BY AFTERNOON AND SOME STORMS COULD BECOME STRONG WITH GOOD MICROBURST POTENTIAL. STORMS SHOULD DIMINISH AFTER SUNSET. THE MODELS INDICATE THERE MAY BE SUBSIDENCE OVER THE AREA ON SUNDAY WHICH MAY STRENGTHEN THE CAP. THEREFORE ONLY A SLIGHT CHANCE ON SUNDAY. ANOTHER TROF AND POSSIBLE MCS MOVE INTO THE REGION MONDAY OR MONDAY NIGHT INCREASING THE CHANCE FOR THUNDERSTORMS AGAIN. NOT MUCH CHANGE IN TEMPERATURE PATTERN AS SUMMER CONTINUES. .PRELIMINARY NUMBERS... BHM 91 71 91 71 89 / 50 20 20 10 MGM 91 71 92 71 90 / 50 20 30 20 .BHM...NONE.
