A cold front that moved slowly east/southeast across Kansas in the afternoon enabled thunderstorms to develop across primarily Southeast Kansas that evening. Damaging 60 to 70 mph winds were by far the primary severe thunderstorm mode although damage was primarily limited to trees.

NWS Wichita, KS wrote its last area forecast discussion before the first event at Jul 21, 5:44 PM CST, 2 minutes earlier.
Area Forecast Discussion National Weather Service Wichita KS 644 PM CDT Sun Jul 21 2019 ...Updated for Aviation Discussion... .SYNOPSIS... Issued at 325 PM CDT Sun Jul 21 2019 The main forecast highlight will be chances of thunderstorms this afternoon through tonight, and the last few hours of excessive heat in southeast Kansas late this afternoon. Otherwise, cooler temperatures accompanying a dry pattern will persist throughout the next week. && .SHORT TERM...(This evening through Wednesday night) Issued at 325 PM CDT Sun Jul 21 2019 Early this afternoon, water vapor and visible satellite imagery show a MCV across southern Nebraska/northeast Kansas. A synoptic front that has become mostly stationary during the day today stretches from the Great Lakes region through central Missouri, and into eastern Kansas before turning more southward through south central Kansas and the panhandles of Oklahoma and Texas. Visible satellite imagery depicts a band of clouds stretching from northeast Kansas, across Saline, McPherson, Rice, and Reno counties and extending southwest into Oklahoma, which appears to be a remnant outflow boundary. As of 19z, some isolated convection has initiated along this band in northwest Barber County. Over the next several hours, convective development is likely to occur as the cap erodes and CAPE continues to increase. Effective bulk wind difference values are less than stellar for severe storm development, but sufficient buoyancy, initiating boundaries as a focus, and maximized residence time within surface-based effective inflow layer air should be sufficient to produce a few strong to severe storms. These will likely be focused along the main MCV in far northeast Kansas/southeast Nebraska/northwest Missouri, as well as along the main synoptic front and outflow boundary. With storms expected to congeal into clusters and line out, the primary threat with these storms will be straight-line wind, with gusts of around 60mph possible. However, severe hail will be possible in initial, isolated development. The overall tornado threat appears low within the forecast area, but mesoscale boundary interactions that could create temporary windows of locally favorable environmental conditions for tornado development will need to be monitored. Additionally, forecast precipitable water values (2.0-2.25 inches) well above climatology for the time of year suggest that heavy rainfall will be a concern as well, as thunderstorms are expected to be efficient rain makers. Localized flooding will be possible, especially in the usual places and in low-lying areas. As thunderstorms push southeast overnight, a big cool-down is expected behind the cold front as surface flow switches to blow out of the north, allowing early morning low temperatures to drop into the 60s in central and south central Kansas but remain a little warmer in southeast Kansas given the timing of the convection and frontal passage. Regardless, storms should be mostly clear of southeast Kansas by mid-morning tomorrow allowing for clearing skies across the entire area in the afternoon as a ridge builds into the region. Afternoon highs will be much cooler than previous days, reaching only into the low 80s area-wide on Monday. This surface ridge is forecast to remain in place for quite some time, so the remainder of the short term will remain precipitation-free with mostly sunny skies and cooler than normal temperatures but with a slight warming trend each day. .LONG TERM...(Thursday through Sunday) Issued at 325 PM CDT Sun Jul 21 2019 As the previous discussion stated, the remainder of the long term forecast will remain quiet as a high pressure regime dominates the central Plains for much of the rest of the week. The slight warming trend should continue each day through the workweek, with highs reaching back into the 90s next weekend. Little change was made to the previous forecast other than the removal of slight chance pops next weekend in favor of a drier scenario. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 641 PM CDT Sun Jul 21 2019 Scattered thunderstorms will move southeast across portions of south-central and southeast Kansas this evening, as a cold front oozes south across the region. Included VCTS at ICT and CNU for now, but amendments for TEMPO +TSRA and strong variable winds may eventually be needed. Thinking activity will exit southeast Kansas by 06-08z. && .PRELIMINARY POINT TEMPS/POPS...
