Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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, Jan 11, 8:50 PM EST, 46 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
850 PM EST Sat Jan 11 2020
.SYNOPSIS...
A strong low pressure system with its associated cold front will
cross the southern Appalachians tonight bringing storms and heavy
rain. After brief drying on Sunday, unsettled weather returns for
the first half of the week. Cooler and dry high pressure will be in
control Thursday and Friday. Another wet system arrives next
Saturday.
&&
.NEAR TERM /THROUGH SUNDAY/...
As of 845 PM EST Saturday: The QLCS has been overperforming so far,
with numerous trees down across western NC and western Upstate SC,
along with NE GA. A few rotating/broken-S signatures are becoming a
bit more common now across the Lake;ands. This along with increasing
sbCAPE of 250-500 J/kg and strong low-level shear (SHERB-3 of 1-
1.25) seems to warrant expanding the Tornado Watch to include all of
the I-77 corridor counties. The watch goes until midnight. The
western part of the watch will be dropped as the line exits to the
east.
Otherwise, CAM guidance shows favorable muCAPE, shear, and helicity
values developing as the squall line approaches. This guidance shows
streaks of updraft helicity moving in as well. The system is very
dynamic, a strong lead short wave does cross the area providing
plenty of forcing even with the main short wave passing to our NW.
there is also quite a bit of divergence as the right entrance region
of an upper jet moves in. This will provide plenty of forcing for
ascent. Despite the clouds and showers across the area, there is no
sign of any cold air damming developing with very anomalously high
temps and dew points in place and gusty southerly winds. When it's
warm, humid, and windy in January, bad things can happen. After
coordinating with SPC, the Slight Risk of severe storms will be
expanded east into our area to give some lead time for a potential
Watch. There are still some timing differences with the squall line
with some guidance faster than others. A couple of runs even show
the initial line weakening and a second line along the front
strengthening. This the faster, stronger initial line scenario is
better. This brings the squall line into the CWFA around 00Z, into
the I-26 corridor by 03Z, and into the I-77 corridor by 06Z. This
could even be a little slow. Will leave the Wind Advisory as is for
now, as the strongest gradient winds will be over the higher
elevations. Stronger winds into the High Wind Warning criteria will
likely be associated with the squall line itself and can be
addressed with Severe Thunderstorm Warnings. Given the strength of
this system and amount of shear and helicity, an isolated tornado is
possible as well. There will still be quite a bit of QPF across the
southern Escarpment and Southwestern NC mountains. However, given
the fast movement of this system, do not expect any widespread
flooding problems. Isolated flooding will be possible.
Weak high pressure builds in behind the front Sunday. The pressure
gradient relaxes quickly given the weakness of the high. Winds
should drop off quickly, even across the mountains. Expect clearing
skies during the morning. The front stalls to our south with waves
of low pressure moving along it. This will bring moisture and clouds
back into the area south of I-85 during the afternoon along low
precip chances. Highs will be 15 to 20 degrees above normal.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
As of 130 PM Sat: Longwave central-CONUS trough and western Atlantic
high pressure will remain in place into midweek. Between these
features, a wavering, weak baroclinic zone will maintain generally
unsettled weather for our FA. This will begin Sunday night as
southwesterly flow atop the old cold front brings it northward again,
and weak isentropic lift occurs overhead; slight elevated instability
could produce the occasional rumble of thunder. The lift over the
front strengthens later Monday, and especially Monday night, in
advance of a low pressure system that will move from the northern
Plains toward the northeast, within the so-called wave train. Models
differ somewhat in how the eastward movement of that low affects the
area but depict the next shortwave in the train soon following
behind. The consensus suggests a drying trend between the lows, and
a decline in PoPs, to end the short range.
Max temps will remain 15 to 20 degrees above normal, with mins on the
order of 25 above normal--close to if not warmer than normal maxes.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 200 PM Sat: The ill-defined baroclinic zone will remain across
the region until one more shortwave crosses the Upper Midwest. This
suggests warm and wet conditions will continue for the FA until cold
front sweeps through sometime Thursday. Though temps will trend down
immediately following the fropa, downsloping will keep them
substantially above normal for one more day. A narrow upper ridge and
strong sfc high then move into the eastern CONUS, setting up dry wx
and more seasonable temps for the region Thu night and Fri. A
full-latitude trough sweeping across the Plains will induce deep
cyclogenesis around that time. As this new system nears the area
Friday night and moisture spreads back in from the west/southwest, it
is not out of the question high elevations will experience mixed
wintry precip.
&&
.AVIATION /02Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: Cigs have mostly gone to VFR or high MVFR
ahead of the approaching squall line. The main concern will be
timing the tstms. Have tried to base the tempo groups on the faster
side of the high-res models, but even that may be too slow. Gusty
south winds will shift to SW with the line and stay SW thru the
period, losing their gusts by daybreak Sunday. Low clouds should
clear out, but a fair amount of cirrus should linger. Not expecting
any fog being the precip early Sunday, due to enough wind lingering.
Outlook: Moisture, precip, and associated restrictions will return
from the south Sunday night and persist thru at least the first half
of next week.
