Heavy rain spread across the region during the late evening of the 29th and continued into the evening of the 30th as a low pressure system moved from the Texas Panhandle to southern Indiana. Widespread rainfall accumulations of one to two inches on already saturated soils led to another round of flooding on some of the same locations that flooded on the 25th.

The episode as NWS SGF wrote it up.
Heavy rain spread across the region during the late evening of the 29th and continued into the evening of the 30th as a low pressure system moved from the Texas Panhandle to southern Indiana. Widespread rainfall accumulations of one to two inches on already saturated soils led to another round of flooding on some of the same locations that flooded on the 25th. During the afternoon, a few strong to severe storms produced hail to the size of quarters and isolated wind damage over Barry, Lawrence and McDonald counties.
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.
NWS Springfield, MO wrote its last area forecast discussion before the first event at Jan 30, 2:42 PM CST, 2 hours 16 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 242 PM CST Sat Jan 30 2021 .SHORT TERM...(Tonight and Sunday) Issued at 242 PM CST Sat Jan 30 2021 Narrow severe threat is the main short term concern followed by lingering drizzle on Sunday. Short term forecast is playing out largely as expected with lapse rates increasing as an upper level low approaches the Missouri Kansas border. Thunderstorms have developed over northeast Oklahoma as instability increases with the arrival of sunshine and surface dew point climb into the lower 50s ahead of an approaching cold front. SREF/CAMS models maintain the window for isolated severe convection from 4 to 7 PM ahead of the front over southeast Kansas into far southwest Missouri. MLCAPES are marginal at 300-400 J/KG with 0-1 SRH ranging from 300-400 initially before diminishing as surface winds veer with the approach of the front. This will yield low top supercells...with hail and wind threats being the primary threat. A tornado cannot be ruled out given the initial low level helicity though would expect this threat to diminish rather quickly as the storms track into Missouri followed by storm updrafts to wain as instability is cut off with sunset. The remaining precipitation will diminish as the upper low tracks northeastward through the CWA. Low level moisture though remains high into Sunday morning suggesting the potential for a light shower or drizzle. Drizzle will again be possible Sunday night as shortwave energy descends off the developing western ridge into the upper level trough positioned along the Mississippi Valley. .LONG TERM...(Monday through Saturday) Issued at 242 PM CST Sat Jan 30 2021 The influence of the upper low will advect off to the east on Monday initiating a warming trend through midweek as heights climb with the arrival of the upper ridge. Split upper flow will bring about uncertainty that will last from Thursday into the weekend as models depict an active pattern though show differences in handling a surge in Canadian air and upper level shortwaves leading to a periodic chance for snow. Confidence in any major snowfall is low at this point. && .AVIATION...(For the 18Z TAFS through 18Z Sunday morning) Issued at 1153 AM CST Sat Jan 30 2021 With rainfall falling across the region...VFR/MVFR will be common though more widespread IFR ceilings along with embedded TSRA will be advecting in from Kansas and Oklahoma into western Missouri during the early afternoon. Per the update above...rainfall rates will also be on the increase over the west impacting visibilities as well. Southeast Kansas into far southwest Missouri will then have a period of isolated severe convection from 20-24 UTC before the rain activity ends from southwest to northeast during the evening into the overnight hours. Low level saturation will however quickly follow on the heels of this clearing leading to lowered MVFR to IFR conditions through early Sunday. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
