The episode as NWS SGF wrote it up.
Daily and monthly rainfall records were set at the region's airports. Rain associated with cold fronts and thunderstorms produced significant rainfall across the region on the 4th, 16th, 28th and 29th. The highest monthly precipitation totals for August 2022 observed from rain gauges within the NWS Springfield Cooperative Observation Network (COOP), and Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) stations and ranged from 6.01 to as much as 8.31 inches for the month.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

...12Z AVIATION UPDATE...
Key Messages:
1. Flood Watch continues until 9 AM this morning. Localized
pockets of 2-4" of rainfall are possible for areas along and east
of the Highway 65 corridor. May see some redevelopment of
isolated to scattered showers/storms later this afternoon and
evening.
2. Isolated to scattered showers and thunderstorms possible again Friday
afternoon into Friday evening over Eastern Ozarks.
3. Excessive heat continues into this weekend. Heat headlines may
be needed in future forecasts.
.SHORT TERM...(Today and tonight)
Issued at 312 AM CDT Thu Aug 4 2022
Current satellite and radar imagery shows a complex of showers and
thunderstorms along a line from Nevada to Bolivar to northern
Shannon County pushing southeastwards. A shortwave rounding about
the northeastern periphery of the upper-level ridge, an
associated surface front and an increasing southwesterly low-level
jet of 20-30 knots have allowed for this development. A moisture-
rich environment with PWATs near 2" (00Z SGF sounding observed
1.85") and training thunderstorms will support heavy rainfall
through this morning, and possibly some localized flash flooding.
Some locations around the Lake of the Ozarks and Harry S. Truman
Reservoir area have observed more than 2-3 inches early this
morning. A Flood Watch continues until 9AM this morning for
locations along and east of Highway 65. 00Z HREF guidance
suggests a widespread 0.5-1.5" with heavier pockets of 2-4" in the
Flood Watch area. These totals are supported by the most recent
runs of the HRRR as well. With 1500-2500 J/kg CAPE and effective
bulk shear in the 20-30 knot range, some of the stronger updrafts
may support some small hail and damaging wind gusts. This main
complex of showers/storms is expected to move south of the area by
midday. We will need to monitor for redevelopment late this
afternoon into this evening as this humid airmass hangs around.
Borderline heat advisory criteria may be met in a few locations
this afternoon, however uncertainties with low-level cloud cover
during the day kept from an issuance. Nonetheless expect
widespread heat index values in the upper 90s and low 100s this
afternoon with a few locations possibly reaching 105. Actual
temperatures this afternoon will range from the mid 90s over
southeast Kansas and southwestern Missouri to upper 80s and low
90s over the Eastern Ozarks.
.LONG TERM...(Friday through Wednesday)
Issued at 312 AM CDT Thu Aug 4 2022
Heat will continue Friday and into the weekend as the ridge
builds over the Central Plains and increasing south-southwesterly
flow allows for 850 mb temperatures in the 20-22 degree C range to
sprawl across the Missouri Ozarks. Heat index values in the
100-105 range, possibly higher, are in the forecast through
Sunday. It will be warmest over southwestern Missouri where
temperatures in the upper 90s are likely. Temperatures in the low
to mid 90s are expected for locations in the Eastern Ozarks and
south-central Missouri through the weekend. Will need to watch for
isolated to scattered convection east of Highway 65 Friday
afternoon and evening as weak upper-level low-pressure gradually
shifting eastward interacts with a hot and humid airmass. High-res
guidance is picking up on this convective activity as well.
Looking forward to the Monday-Tuesday time frame next week, a
shortwave trough looks to progress eastwards into the Upper
Midwest with an associated cold front dipping south into the
Missouri Ozarks. All clusters in the WPC Cluster Analysis Tool
show precipitation over the CWA Monday and Tuesday with a few
members suggesting some lingering precipitation into Wednesday. A
general "cooldown" is looking more probable during this time frame
(mid 80s to mid 90s), however NBM temperatures spreads are quite
wide and highlight some uncertainty with temperatures next week.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 620 AM CDT Thu Aug 4 2022
Showers and thunderstorms can be observed across the Missouri
Ozarks this morning as an upper-level wave progresses eastward
across the area. This complex of showers/storms is expected to
push south of the TAF sites by late this morning (14Z-16Z).
Lowered VFR ceilings and MVFR ceilings have been observed with
this activity, some IFR at KBBG. Ceilings will lift back to VFR
status by midday as this activity pushes away from the TAF sites.
IFR to MVFR visibilities can be expected under the heavier storms.
Some isolated to scattered shower/storm redevelopment will be
possible late this afternoon into this evening, but confidence was
too low to include in this TAF issuance.
