The episode as NWS DVN wrote it up.
During the late afternoon of July 5th, scattered showers and storms increased in coverage becoming widespread across the area. Some of these storms led to severe weather in Muscatine, Scott, and Clinton Counties. Damaging straight-line winds of 60 to 70 MPH were reported.
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 Quad Cities, IA wrote its last area forecast discussion before the first event at Jul 5, 1:33 PM CST, 1 hour 36 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Quad Cities IA IL 233 PM CDT Sat Jul 5 2025 .KEY MESSAGES... - Scattered to widespread showers and thunderstorms are forecast this afternoon into tonight (50-80%), a few of which could become strong to severe - Occasional chances of showers and storms remain in the picture through next week, but with plenty of dry periods interspersed && .SHORT TERM /THROUGH SUNDAY/... Issued at 231 PM CDT Sat Jul 5 2025 A more active day remains on tap today, with increasing chances of showers and storms (50-80%) this afternoon lingering into tonight. The culprit is a mid-level shortwave trough and attendant cold front that is approaching the region from the northwest. Some isolated strong to severe storms are possible. Analysis of the convective parameter space indicates that damaging winds will be the primary threat due to copious PWAT values in excess of 2 inches (near the maximum for the DVN 06.00z sounding climatology per SPC). Additionally, steep low-level lapse rates will be in place, which should combine with the high PWATs to result in the threat for some locally strong wet microbursts. As such, SPC has maintained a Marginal Risk (level 1 of 5) for severe storms for most of the CWA, save for the far southeastern areas. Storms look to come in two waves, with the first having more scattered coverage this afternoon along a pre-frontal trough, and a second more widespread round as the cold front moves through. Storms should begin to diminish after midnight tonight. With the anomalously high PWATs and high freezing levels around 16,500 ft per the 05.12z DVN RAOB, these conditions are supportive of torrential downpours due to efficient warm rain processes. Therefore, a secondary risk today is localized flash flooding with urban areas most at risk. Latest HREF ensemble QPF PMM values indicate total rainfall through tonight between 0.5 to 1.5 inches for a large portion of the area, with some isolated areas around 2 inches possible. Any lingering showers and storms around midnight tonight are expected to gradually diminish thereafter per the latest suite of CAMs. The bulk of the forcing with the front will remain to our south and east on Sunday, but a few isolated showers and storms can't be ruled out with a mid-level trough continuing to exit the area. Theta-e values will be lower, and with a lack of deep-layer shear and weaker low-level lapse rates, strong storms are not anticipated. Temperatures on Sunday will be more seasonal compared to the last few days, with highs warming to the lower to middle 80s. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... Issued at 231 PM CDT Sat Jul 5 2025 Zonal flow aloft will be the norm for next week, which will help maintain seasonable July temperatures and humidity levels. Next week will continue to have periodic chances of showers and storms, particularly for Tuesday through Friday, as a series of mid-level shortwaves look to sweep through the area, but widespread rainfall is not anticipated. Confidence remains generally low this far out on the timing of these systems with 20-40% chances of showers and storms per the NBM. Despite the lower confidence, there are some signals in the various extended machine learning output for the potential for isolated strong to severe storms Tuesday through Friday, so something to be mindful of as we go through the upcoming week. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1240 PM CDT Sat Jul 5 2025 Increasing chances of thunderstorms remain on tap for this afternoon as a trough of low pressure approaches the area. Brief MVFR to IFR conditions are possible under the heavier downpours, with visibilities as low as 2SM possible. Additionally, some gusty and erratic winds are possible with some of the stronger thunderstorms. A cold front will sweep through this evening into tonight, leading to yet another round of showers and thunderstorms, with more potential for locally strong wind gusts. Not only will winds turn more northwesterly behind the front, but cooler air will help support lowering ceilings down to at least MVFR, if not IFR, with confidence in IFR cigs highest near DBQ. && .DVN WATCHES/WARNINGS/ADVISORIES...

Spotter activation may be needed this afternoon and evening. Uttech
