The episode as NWS ARX wrote it up.
After a locally heavy rain event in early July, some river flooding occurred along the Kickapoo River in Ontario (Vernon County).
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 La Crosse, WI wrote its last area forecast discussion before the first event at Jul 3, 9:57 PM CST, 6 minutes earlier.
Area Forecast Discussion National Weather Service La Crosse WI 1057 PM CDT Wed Jul 3 2019 .SHORT TERM...(This evening through Thursday) Issued at 326 PM CDT Wed Jul 3 2019 At 3 PM, a cluster of showers and thunderstorms was located across southeast Minnesota. This cluster was moving northeast and it is expected to continue to move through west-central Wisconsin and potentially through north-central Wisconsin through this evening. With downdraft CAPES between 1000 and 1200 J/kg, there is a potential for some strong, gusty winds in areas where a core collapses. In addition, maybe some hail in the half to 1 inch range. Further to the east and southeast, there are isolated to scattered showers extending from northern Houston County through Madison. With weak convergence, expect not much change in this activity as it moves northeast though Central Wisconsin. Elsewhere, there are scattered showers and storms in western Iowa. This is associated with a MCV. The ESSRL HRRR seems to have a good handle on this activity and it shows that this precipitation will move northeast across northeast Iowa and central and southwest Wisconsin late this afternoon and evening. With very weak shear, not anticipating any organized severe weather. However, would not be too surprised to see some gusty winds from them. On the 4th, a shortwave trough will be moving slowly east through the area. Like today, ML CAPES will range from 2000 to 3000 J/kg and the 0-3 km and 0-6 km will remain weak. The CAMs continue to show multiple lines of storms moving through the area. The first line moves through from mid to late morning into the early afternoon. The second line moves through from mid to to late afternoon into the evening. A few of these storms could be potentially strong in either of these lines. .LONG TERM...(Thursday night through Wednesday) Issued at 326 PM CDT Wed Jul 3 2019 On Friday afternoon and evening, another shortwave trough will move east through the region. ML CAPES will range from 1500 to 3000 J/kg. The 0-3 km and 0-6 km shear is stronger than this afternoon and Thursday afternoon, but still is not strong enough for organized convection. However, there is still the potential for a couple of pulse storms. The main threat would be gusty winds. It still looks like high pressure will build across the area for the upcoming weekend. This high will provide mainly dry conditions for much of the forecast area. If showers and storms were to develop, they would be located near Interstate 35. For early next week, the front will move back north into the area. This will bring a return of showers and storms to the area. && .AVIATION...(For the 06Z TAFS through 06Z Thursday night) Issued at 1049 PM CDT Wed Jul 3 2019 Dry conditions expected at both TAF sites overnight. With plenty of residual low level moisture from high humidity and recent rainfall, there will once again be fog potential late tonight, but the setup does not look quite as favorable as last night. MVFR visibilities will be possible, with perhaps a dip into IFR for a short time. Main concern on Thursday will be a disturbance pushing through the area in the afternoon, which is expected to pop scattered showers and thunderstorms across the area. Still some lingering uncertainty with timing and coverage of this convection, so have left thunder out of this TAF issuance and have gone with tempo showers. Locally heavy rainfall and some gusty winds will be possible with any storms that develop, and this activity should diminish towards sunset. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None.
