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.

National Weather Service Springfield MO
235 PM CDT Tue Jul 25 2017
.SHORT TERM...(This evening through Wednesday)
Issued at 235 PM CDT Tue Jul 25 2017
Hot and humid conditions continue across the region this
afternoon. A couple of showers have developed across south central
Missouri, and this potential will continue through the remainder
of the afternoon hours. Anything that does develop should
dissipate as the sun begins to set this evening.
A warm and muggy night is then expected overnight with lows in the
low to mid 70s.
Wednesday looks to be the hottest day of the week, with
widespread mid 90s temperatures. With dewpoints in the 70s, heat
indices should top out between 103 and 107 across the entire area.
A Heat Advisory will be in effect for the entire region from noon
through 8 PM Wednesday.
.LONG TERM...(Wednesday Night through Tuesday)
Issued at 235 PM CDT Tue Jul 25 2017
A cold front will begin to approach the area from the north on
Thursday, with associated cloud cover and precipitation keeping
temperatures a little cooler, with highs in the upper 80s and low
90s. Thunderstorms look to be a decent bet along the front during
the afternoon/evening hours, and while shear will be weak,
abundant low level moisture may yield a wind/microburst threat as
convection moves through. Locally heavy rain is also possible,
though this may be a welcomed sight in many areas.
Cooler and drier air will then filter into the area
Friday/Friday night and especially Saturday, setting the region up
for a very nice weekend. Temperatures should be in the mid 80s,
with dewpoints in the 50s and low 60s. This will be a very
welcomed break from the stretch of warm and humid weather that has
been in place for the last few weeks.
&&
.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1212 PM CDT Tue Jul 25 2017
VFR conditions are expected over the next 24 hours as fair weather
continues across the area. There will be a few isolated
thunderstorms through the afternoon hours, but coverage is too low
for TAF inclusion at this time. Winds should remain light from the
south to southwest.
