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, 11.1 hours before the alert went out and 9 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.

04-MCDWhat 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 Jun 8, 2:44 PM EDT, 4 hours 23 minutes earlier.
Area forecast discussion, Jun 8, 2:44 PM EDT, 4 hours 23 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 244 PM EDT Fri Jun 8 2018 .NEAR TERM [Through Tonight]... Shower and thunderstorm activity that is currently on-going across the Florida Panhandle and Big Bend will dwindle with the loss of daytime heating this evening. An isolated shower or two may linger for a few hours after sunset given the weak forcing provided by a stagnant upper level low centered over the far northeast Gulf of Mexico. Otherwise, partly to mostly cloudy skies are expected overnight with lows generally around 70 degrees. .SHORT TERM [Saturday Through Sunday Night]... An upper low positioned over north Florida Saturday will meander in the weakness between the Bermuda ridge and the ridge centered over Mexico. Deep layer moisture will remain in place with PW's ranging from 1.7" and 2.0". This combined with daytime heating and sea breeze interaction will lead to seasonal to above seasonal chances for scattered showers and thunderstorms. Highs will mainly range from the mid 80s to lower 90s, with lows from the upper 60s to lower 70s. .LONG TERM [Monday Through Friday]... The upper level trough will remain over the region going into the long term, maintaining the same generally unsettled sea breeze pattern. Rain chances will be highest during the day throughout the period, though slightly lower on Wednesday due to a brief drying of the mid-levels. High temperatures will stay in the mid- upper 80s, while low temperatures will be in the low-mid 70s. && .AVIATION [Through 18Z Saturday]... TSRA has developed along the FL panhandle and big bend coasts and continues to move inland. TLH, ECP and VLD have the highest likelihood of being affected this afternoon. Brief reductions in CIGs, along with gusty winds will be possible under any TSRA activity. Otherwise, VFR conditions and easterly to southeasterly winds AOB 10kts will prevail through the period. && .MARINE... Light winds and low seas will prevail through the next several days across coastal waters. && .FIRE WEATHER... Hazardous fire weather conditions are not expected over the next several days. && .HYDROLOGY... A few river gauges across our area are currently continuing to fall through action stage, and all gages are likely to be below action stage by this weekend. Scattered showers and thunderstorms will produce brief, isolated areas of heavy rain each day across our area, but this is not expected to result in any river flooding. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
