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
Tallahassee Rgnl, FL (KTLH), launched 12:00Z, 7.2 hours before the alert went out and 155 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.

42-DVDWhat forecasters said that day
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 Tallahassee, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 21, 6:53 AM EDT, 8 hours 19 minutes earlier.
Area forecast discussion, Jul 21, 6:53 AM EDT, 8 hours 19 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 653 AM EDT THU JUL 21 2016 .AVIATION [Through 12Z Friday]... VFR conditions are expected today outside of any thunderstorms. Scattered TSRA is expected this afternoon, mainly after 17z across the southern TAF sites and starting a little later around 21z across the northern TAF site areas. && .PREV DISCUSSION [347 AM EDT]... .NEAR TERM [Through Today]... CWA remains on the eastern side of an upper level ridge to the west with a trough along the eastern U.S. coast, resulting in northerly flow aloft across the CWA. Do expect to see a more active day than yesterday, both in regards to seabreeze thunderstorms and storms sinking into the CWA from the north. No clearly defined short waves in the ECMWF or GFS but the NAM is picking up on a later start with less seabreeze activity and then a complex sliding in from the northeast. Still think we'll see the seabreeze activity after 18z, but then late in the afternoon scattered storms could slip down into the northern portion of the CWA. SPC has included the majority of the CWA in a slight risk for today - could see a few strong and severe storms with the main threat being damaging wind. Another hot day is in store across the tri-state area with mid to upper 90s forecast for highs today. While this results in heat indices in the 104-107 degree range, which is below heat advisory criteria, it's still a good idea to follow heat safety rules such as limiting time outside and staying hydrated. .SHORT TERM [Tonight Through Saturday]... Ridging over the Central CONUS remains in place through Friday before the pattern begins to break down. In this flow regime, late day convection tends to filter in from the Carolinas and this is depicted well in the 21/00z NAM which shows convection from Thursday continuing across the area until at least 06z Fri. The NAM is quite aggressive, however, with little support for such widespread coverage in the other models, so will keep PoPs in the low chance range for tonight. On Friday, with the ridge still off to the west, expect a late start to convection and generally scattered coverage at best. Expect it to continue to be quite warm, with highs in the mid to upper 90s and heat indices topping out in the 104-106 degree range in the afternoon. By Saturday, ridging across the Central CONUS will begin to weaken slightly, which should lead to a little better coverage of afternoon storms across the region, though still below normal for what would typically be seen in late July. .LONG TERM [Saturday Night Through Thursday]... The first half of the long term period should feature a return to near normal rain chances through Monday with the absence of the strong ridge over the Plains. By Tuesday, ridging from the Western Atlantic spreads westward into NE Florida, which should result in a decrease in afternoon rain chances and an increase in afternoon highs back to the upper 90s across inland areas. .MARINE... High pressure will continue to dominate the northern Gulf Coast. As a result, winds will generally remain 10 knots or less and seas of 2 feet or less. .FIRE WEATHER... With RH values above critical thresholds, hazardous fire weather conditions are not expected over the next several days. .HYDROLOGY... Isolated to scattered afternoon and early evening thunderstorms are expected each day. There are no widespread flooding concerns at this time. However, isolated heavy rainfall will be possible with slower moving thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
