The radar
The Springfield radar (KSGF), 55 km from the middle of the area, began a volume at 03:32 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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
Springfield, MO (KSGF), launched 00:00Z, 3.5 hours before the alert went out and 79 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.

GriffinWhat 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 Springfield, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Jan 21, 6:07 PM CST, 3 hours 20 minutes earlier.
Area forecast discussion, Jan 21, 6:07 PM CST, 3 hours 20 minutes before
Area Forecast Discussion National Weather Service Springfield MO 607 PM CST Sun Jan 21 2018 ...Mesoscale and Updated Aviation Discussion... .MESOSCALE DISCUSSION... Issued at 528 PM CST Sun Jan 21 2018 At this point, this "event" is going as planned. A broad corridor of convection has developed from northeastern Texas into eastern Oklahoma and southwestern Missouri. This convection is developing over an area of 0 to 0.5 km AGL convergence on the eastern periphery of increasing 500 mb height falls. Instability remains weak with the ongoing 00Z SGF RAOB measuring 117 J/kg of MLCAPE. The lower level capping inversion present on the 21Z sounding has been removed, however a secondary (higher) inversion remains in place and is resulting in the presence of some inhibition. Instability farther south across the Arklatex into the I-40 corridor is a bit better, with MLCAPE values on the order of 500 to 900 J/kg. We have seen some low-topped supercells with decent low-level rotation along with QLCS mesovortex structures down south across this region. As we head throughout the evening, it will be very difficult for this better instability to reach the Missouri Ozarks as convection will continue to develop and impede its progress northward. We will see cooling mid-levels which may offset this slightly. Deep layer and low-level shear will remain robust as mid/upper level jet cores impinge on the region and a low level jet strengthens and noses into southern Missouri. With all of that said, we are going to maintain a limited severe weather risk as this broad area of convection slowly shifts east with time across the Missouri Ozarks. Despite the lack of instability, these setups can be conducive to line segments with mesovortex potential. Mesovortices will be more favored with bowing structures towards the east, northeast, or north. We may also see some low-top supercell structures early this evening over far southwestern Missouri. One other item of note will be the potential for a few additional cells to develop back to the west closer to I-49 corridor late this evening as even stronger height falls overspread an accelerating dry line/surface trough. Instability may briefly increase as this happens as strong mid-level cooling takes place. If these cells can develop, they may have a limited hail risk. && .SHORT TERM...(This evening through Monday) Issued at 130 PM CST Sun Jan 21 2018 A deep closed upper low will track from the Rockies into the central Plains this evening while a surface low pressure system tracks from eastern Kansas into northern Missouri. A trailing surface trough then cold front will push across the Ozarks region this evening. Strong synoptic lift and moisture advection along with at least ample instability will ignite numerous showers and thunderstorms from late afternoon into tonight. While instability will be rather modest the shear profiles will be favorable to support intense updrafts and possibly supercells. Shear vectors will also support surging line segments and bowing structures. This all adds up to a risk of severe storms with the potential of damaging winds and possibly a couple of tornadoes. While a low risk the primary area of concern for tornadoes would be across far southern Missouri. The showers and storms will end from the west late this evening into the overnight hours. Expect some clearing overnight as a dry slot wraps around the upper low. The true cold front will sweep across the area early Monday as the upper low transitions eastward. This will bring steady or falling temperatures and increased cloud cover. Also expect showers mainly across central Missouri. Some potential that some snow will mix with the rain before ending. .LONG TERM...(Monday Night through Sunday) Issued at 130 PM CST Sun Jan 21 2018 Colder temperatures settle back into the region through mid week before upper level ridging and southerly winds return by late week. The next upper trough and associated front will move into the region heading into later Friday and this weekend. This will bring another good chance for precipitation. Colder weather will again follow this system this weekend. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 528 PM CST Sun Jan 21 2018 Showers and a few thunderstorms can be expected across the region this evening as a strong storm system approaches from the west. MVFR and brief IFR conditions can be expected around storms. Meanwhile, low level wind shear conditions can be expected along with brisk and gusty southerly surface winds. Most of the shower and thunderstorm activity will then shift east of the area for the overnight period with predominantly VFR conditions then expected. MVFR ceilings will then settle back into the region on Monday as the upper level portion of this storm system tracks into the region. Strong and gusty surface winds will also continue with southwesterly gusts exceeding 35 knots. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
