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 00:00Z, 1.0 hours before the alert went out and 148 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, Apr 14, 6:43 PM EDT, 2 hours 16 minutes before
Area Forecast Discussion
National Weather Service Tallahassee FL
643 PM EDT Tue Apr 14 2020
.AVIATION...
[Through 00Z Thursday]
VFR conditions at TLH and VLD deteriorate to MVFR with TSRA
following into early Wed morning. Cigs lower overnight to
IFR/LIFR, then return to VFR by Wed afternoon. Otherwise, for
remainder of the TAF sites, VFR may be punctuated by brief
MVFR cigs around daybreak. Light and variable winds become
north 5-10 knots.
&&
.PREV DISCUSSION [356 PM EDT]...
.NEAR TERM [Through Wednesday]...
The main forecast challenges this evening will be timing the
onset of precipitation and potential for strong thunderstorms.
Based on the latest trends, have pushed back the onset of more
widespread precip into this evening, affecting the area mainly
southeast of a Miramar Beach to Fitzgerald line. SPC maintains
a marginal risk of severe thunderstorms from Apalachicola to
Valdosta southeastward. Instability is limited across this area
given the earlier convections stabilizing effect, and this is
evident in extensive stratiform clouds. The bottom line is that
an isolated strong to severe thunderstorm or two is possible
east of the Flint and Apalachicola Rivers, with damaging winds
and marginally severe hail the main threats thru this evening.
After a brief reprieve early tonight, expect thunderstorms to
develop over the gulf and move into the southeast FL Big Bend
late tonight into Wednesday morning. SPC maintains a marginal
risk across this area, and stronger storms will be capable of
isolated wind damage through the afternoon. The remainder of
the area will remain dry on Wednesday with light north winds.
.SHORT TERM [Wednesday Night Through Friday|]...
Drier air will build in behind the front into Thursday morning as
high pressure noses in. PoPs will steadily taper from the
northwest and basically end over our southeast counties on
Thursday. With drier air in place and only weak CAA behind the
front temperatures will rebound quickly with reading back around
80 on Friday. Some convection will be possible late Friday mainly
over the waters as some moisture return begins.
.LONG TERM [Saturday Through Tuesday]...
Moisture return continues on Saturday ahead of the next Pacific
short wave. PoPs will ramp steadily with decent rain coverage
expected over the area. Medium range guidance has been
inconsistent handling the strength of this system esply into
Sunday as the Euro now has a stronger surface low tracking across
the southeast whereas the GFS did on previous runs. Sunday could
be potentially active over the area depending on how this splays
out so stay tuned. Looks drier right now early next week although
this could change with very fast westerly flow and a series of
Pacific short waves moving through.
.MARINE...
Thunderstorms...some strong...will affect the waters through
Wednesday before a cold front pushes through. Winds behind the
front will get close to cautionary levels then subside by Thursday
as high pressure builds in. More thunderstorms are expected late
Friday through the weekend as a series of upper level disturbances
pass through.
.FIRE WEATHER...
Hazardous fire weather conditions are not expected.
.HYDROLOGY...
Rises have been occurring on area rivers in response to heavy rain
upstream over the weekend but no flooding is forecast. Additional
locally heavy rains through the weekend may trigger some
additional rises but right now it appears flooding along our
rivers is unlikely.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur (while following all local, state, and CDC guidelines) by
calling the office or tweeting us @NWSTallahassee.
