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 12:00Z, 11.6 hours before the alert went out and 291 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.

What 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 St. Louis, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 5, 6:05 PM CDT, 30 minutes earlier. Its key messages:
- Isolated to scattered showers and thunderstorms are expected through this evening. A few of which could be capable of gusty winds.
- At least patchy fog is possible overnight into Monday morning, especially in locations that receive rainfall today. Dense fog cannot be ruled out.
- Seasonable temperatures are forecast through the first half of the week.

Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 605 PM CDT Sun Jul 5 2026 .KEY MESSAGES... - Isolated to scattered showers and thunderstorms are expected through this evening. A few of which could be capable of gusty winds. - At least patchy fog is possible overnight into Monday morning, especially in locations that receive rainfall today. Dense fog cannot be ruled out. - Seasonable temperatures are forecast through the first half of the week. && .SHORT TERM... (Through Tuesday) Issued at 245 PM CDT Sun Jul 5 2026 Within an overhead upper-level longwave trough, an MCV is propagating slowly eastward across southeastern MO/far southwestern IL early this afternoon with lingering showers. However, another MCV/low is departing IA and progged to track southward through MO through this evening, which will support isolated to scattered showers and thunderstorms this afternoon and evening, focused in confluent surface flow axes and a differential heating zone along/north of I-70. With weak (10 to 20 kt) deep-layer wind shear, instability lower than Saturday, and not as much dry air in soundings; it is less likely that any thunderstorms will be able to produce damaging winds, but "inverted-V" sounding signatures still suggest they could still contain gusty winds. Following sunset and the loss of daytime heating, showers and thunderstorms will wane. Predominantly dry conditions are expected overnight through Monday morning, but light surface winds, residual PBL moisture, and locations of rainfall today point to a threat of at least patchy fog. Fog would be most likely in locations that have moistened soils from rainfall today and typical river valleys with the potential for dense fog needing to be monitored. On Monday, model guidance, although varied, indicates that the MCV/low will continue to meander and potentially become cut off near southern MO or AR, assisting isolated to scattered diurnal showers and thunderstorms mainly south of I-44 (MO) and I-70 (IL). These locations will have the greatest instability and lingering moisture as weak low-level northerly flow along a building surface pressure ridge attempts to filter a slightly cooler and drier airmass into the CWA. Accordingly, high temperatures will be another degree or two cooler with lower dewpoints as well. Tuesday will be similar to Monday, but rising heights behind the cutoff low as an upper-level ridge arrives and even lower instability/moisture will lead to minimal diurnal showers/thunderstorms. Pfahler && .LONG TERM... (Wednesday through Next Sunday) Issued at 245 PM CDT Sun Jul 5 2026 The influence of the aforementioned upper-level ridge will only persist through Wednesday before it flattens and gives way to quasi- zonal flow across the Mid-Mississippi River Valley through Thursday and Friday. Multiple shortwave troughs within this flow will force a weak, slow-moving/wavering front into the CWA sometime during the Thursday-Friday time period leading to one or more opportunities for showers and thunderstorms along with pre-frontal, low-level southerly flow warming temperatures back to above average at least briefly on Thursday. With humidity/dewpoints also increasing, global model ensemble probabilities of 100+ F heat index values are 15 to 20 percent on Thursday. Over next weekend, global model guidance signals that upper-level flow will veer to northerly ahead of a much more substantial upstream ridge favoring southward movement of the front with a slightly cooler airmass arriving in its wake. The longevity of this airmass is uncertain with model solutions varying on how long northwesterly flow holds before the ridge extends eastward, which would favor warming temperatures. During this time, NBM interquartile temperature ranges span 5 F between below average and average. Pfahler && .AVIATION... (For the 00z TAFs through 00z Monday Evening) Issued at 601 PM CDT Sun Jul 5 2026 Thunderstorms will continue to percolate nearby Jefferson City and Columbia near the start of the TAF period, but are expected to diminish before sunset. Occasional visibility reductions and erratic wind gusts/direction changes will be possible, but shortly thereafter winds should become nearly calm. Overnight through tomorrow morning, the main concern will be fog due to clearing skies, light winds, and lingering humidity and surface moisture from this evening's rain. This will be most likely at central MO terminals and river valley locations (JEF/SUS/CPS/SUS), but will be possible in most areas. Fog should diminish shortly after sunrise. MVFR cumulus will be briefly possible late morning/early afternoon before ceilings lift, and there is a low (20%) chance of showers/weak thunderstorms tomorrow afternoon at St. Louis area terminals. Chances are too low to include in the TAF at this time. BRC && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None. IL...None. && WFO LSX
