The radar
The St Louis radar (KLSX), 100 km from the middle of the area, began a volume at 09:24 UTC, the scan nearest the moment this went out.

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.

BAHWhat 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 Jun 1, 3:58 AM CDT, 27 minutes earlier. Its key messages:
- There will be two rounds of thunderstorms today, one early this morning and another over southeast Missouri and southwest Illinois this afternoon. Damaging winds, large hail, and heavy rainfall are possible with the strongest storms.
- Dry weather is expected Tuesday through Thursday before the chances for showers and thunderstorms returns later this week into next weekend.
Area forecast discussion, Jun 1, 3:58 AM CDT, 27 minutes before
Area Forecast Discussion National Weather Service Saint Louis MO 358 AM CDT Mon Jun 1 2026 .KEY MESSAGES... - There will be two rounds of thunderstorms today, one early this morning and another over southeast Missouri and southwest Illinois this afternoon. Damaging winds, large hail, and heavy rainfall are possible with the strongest storms. - Dry weather is expected Tuesday through Thursday before the chances for showers and thunderstorms returns later this week into next weekend. && .SHORT TERM... (Through Late Tuesday Afternoon) Issued at 356 AM CDT Mon Jun 1 2026 Thunderstorms continue to show a gradual increase in intensity and severity early this morning on the nose of a broad low level jet across Missouri. There remains the potential for severe thunderstorms the remainder of the morning as the thunderstorms over central and western Missouri develop a cold pool which could cause upscale growth across the CWA into a line segment bringing some damaging winds and hail with the stronger storms given the current 1000-2500 MLCAPES and effective shear of 30-40 knots. The environment this morning also remains favorable for storm producing heavy rainfall given the current PWATS and warm cloud depths, particularly if they can train in any one location for very long. The CAMS including the HRRR have this first round of convection moving through the CWA by around 9-10 am. It will lay out of the outflow boundary that will allow for additional shower and thunderstorm development this afternoon. RAP soundings from Farmington this afternoon are showing MLCAPES between 2000-3000 J/kg with around 30 knots of deep layer shear. This should be sufficient to to produce an isolated threat for damaging winds and large hail into the early evening hours. Drier weather is expected from mid evening on as the HREF is showing the high building down the upper Midwest. Highs today will recover back into the 80s behind this morning's storms but should be a few degrees cooler tomorrow with cold air advection. Britt && .LONG TERM... (Tuesday Night through Sunday) Issued at 356 AM CDT Mon Jun 1 2026 Dry weather is still expected Wednesday into Thursday as the upper ridge moves south across the area. As the ridge continues to move to the south, the chance of showers and thunderstorms will return to the area late this week into the weekend as moisture returns north into the area ahead of western trough. High temperatures are expected to return into the mid to high 80s. Britt && .AVIATION... (For the 06z TAFs through 06z Monday Night) Issued at 1106 PM CDT Sun May 31 2026 The focus for impacts this period continues to be showers and thunderstorms through this morning. The main corridor for these showers and thunderstorms will stretch from near KCOU and KJEF east-southeastward through KSUS, KSTL, and KCPS. KUIN has a low chance of being grazed by this activity, though confidence in this occurring is dwindling. Storms will be capable of heavy rainfall that will reduce visibilities to MVFR and even IFR flight categories, and there is a very low chance for gusty, erratic winds and small hail at KCOU and KJEF. Showers and thunderstorms will move south of the local terminals by mid morning, with confidence high in VFR flight conditions through the remainder of the day.
