The episode as NWS SGF wrote it up.
During the morning hours, the tail end of a mesoscale convective complex moved southeastward from the Central Plains into central and south-central Missouri through the early afternoon. Heavy rain fell in a band from Warsaw through Marshfield to Gainesville, with accumulations of one to two inches. Isolated reports of thunderstorm wind damage to trees and power lines were received from Camden, Pulaski, Ozark, and Phelps counties.

Area Forecast Discussion
National Weather Service Springfield MO
609 AM CDT Wed Jul 1 2020
.SYNOPSIS...
Issued at 240 AM CDT Wed Jul 1 2020
MCS over eastern Nebraska was now beginning to make the turn to
the southeast into the better instability axis. CAMS models show
this occurring, but with differing solutions on how much of the
CWA is affected by the convection this morning. Still have the
weak low trapped underneath an upper ridge over the mid/upper
Mississippi valley region. Southwesterly low level jet across the
plains and into western MO and significant ML CAPES over 4000 j/kg
over eastern KS. The main focus for today will be the evolution of
the ongoing MCS and then with heat index values this afternoon.
The remainder of the forecast will also be on low precipitation
chances and with the heat / heat index.
&&
.SHORT TERM...(Today and tonight)
Issued at 240 AM CDT Wed Jul 1 2020
NAMNest takes the MCS all the way across our eastern counties
through the morning and into the early afternoon while HRRR mainly
clips the northeast CWA this morning and then the outflow
reignites some convection, but mainly south of the CWA later this
afternoon. Believe the answer probably lies somewhere in the
middle. Have the higher pops in the eastern CWA today (not high
enough if the NAMNest verifies) which is indicated by all the
models as stronger capping inversion will be over the western CWA.
Will monitor the evolution of the MCS during the remainder of the
overnight and may need to up pops depending on that evolution.
There is a marginal risk of severe storms today in the eastern CWA
with wind gusts up to 60 mph and hail up to quarter size. Western
CWA looks downright hot today with highs in the mid 90s and heat
index values from 102 to 108. Heat advisory which was issued on
the day shift yesterday still looks valid and at this point
probably not extended to the east given the MCS heading to the
southeast towards the eastern Ozarks later this morning. That will
keep temperatures there cooler in the upper 80s to around 90.
For tonight, the convection should be much more spotty. Models do
develop some convection in southeast Kansas and push it into
western MO along a frontal boundary nearly stationary over the
area. Not real gung-ho on this with the upper ridge and capping
inversion over the area. For now am keeping things dry in the west
tonight with lows in the mid 70s and upper 60s to low 70s in the
east.
.LONG TERM...(Thursday through Tuesday)
Issued at 240 AM CDT Wed Jul 1 2020
It looks like another hot day in the west and another heat
advisory will likely be needed at least there for Thursday. Will
let the day shift take a look at another round of models to make
that call. Will probably see some scattered convection again,
especially during the afternoon with the better chances in the
eastern Ozarks.
Will likely see more scattered convection continue into Friday,
but will be less likely heading into Saturday as moisture levels
decrease. Highs will be slightly cooler with readings from the
upper 80s to low 90s and then low to mid 90s for the first part of
next week. Can't rule out diurnal thunderstorm chances just about
every day, however coverage doesn't appear to be significant at
this time.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 605 AM CDT Wed Jul 1 2020
For the 12z TAFS...Convective complex heading into central
Missouri early this morning should remain northeast of the
forecast points. Warm mid level temperatures will likely keep
convection at bay at the TAF sites, at least chances are too low
to consider mentioning in forecast for now. May see some wind
gusts up to 20 kts at JLN this afternoon. Otherwise, expecting VFR
conditions through the period.
