The episode as NWS ICT wrote it up.
On the evening of the 25th, a few thunderstorms produced locally torrential rains in Reno and Kingman Counties. In extreme Southwest Kingman County, 5.10 inches were measured 3 miles north of Nashville. The only flooding that was reported occurred in far Western Reno County, but it's likely that flooding also occurred in Western Kingman County as well.
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 Wichita, KS wrote its last area forecast discussion before the first event at Sep 25, 5:14 PM CST, 1 hour 12 minutes earlier.
Area Forecast Discussion National Weather Service Wichita KS 614 PM CDT Mon Sep 25 2017 .SHORT TERM...(This evening through Wednesday night) Issued at 311 PM CDT Mon Sep 25 2017 Slow moving frontal boundary will continues to make slow progress across the forecast area this evening through tonight, with showers and embedded thunderstorms training along the front for most of central and south central KS. Blocky upper air pattern continues across the US (with strong upper high over the SE US), with flow pattern across the plains parallel to the front leading to a gradual shift to the east of the front for the evening and overnight hours as the main shortwave along the front range slowly shifts to the northeast. This will lead to the showers and embedded storms gradually shifting to the east this evening and overnight, with occasional showers and storms. Lots of low level moisture transport along or just ahead of the front, with precipitable water values of 120-140 percent of normal. Instability is around 1000 j/kg so still could see some embedded thunder strong storms along the leading edge of the shower/storm shield. So with the slow movement of the boundary, and training showers along the front, could see some areas pick up 1 to 3 inches of (much needed) rainfall by Tue evening. Think the heaviest rainfall amounts will be along or just west of the KS turnpike, where instability will be the highest. With the recent dry period, and fairly high flash flood guidance values, not expecting widespread flooding to be an issue, but could see some ponding of water in low lying areas and rises along local rivers and streams. Moisture transport veers to the southeast by Tue, and the synoptic front will slowly shift to areas east of the KS turnpike by Tue night, with some areas of SE KS still seeing lingering showers through Tue night. Latest model solutions suggest main synoptic front will push south into OK for Wed, but lingering mid level baroclinic zone and moisture transport over the top of the boundary may lead to showers lingering over southern KS at least through Wed. so will keep a low pop in for this chance. As the front pushes south, cooler more seasonal type temps with highs in the 70s and lows in the 50s look to return to the region. Ketcham .LONG TERM...(Thursday through Monday) Issued at 311 PM CDT Mon Sep 25 2017 Ridging looks to shift over the region for Wed night through Fri, with drier air moving into the northern plains. This will lead to the seasonal (fall) temps continuing into the weekend as well. Upper ridging looks to flatten out for the weekend, with chances of showers and a few storms increasing for Sat/Sun. Ketcham && .AVIATION...(For the 00Z TAFS through 00Z Tuesday evening) Issued at 614 PM CDT Mon Sep 25 2017 Widespread MVFR and areas of IFR will prevail behind a slow moving cold front across central Kansas tonight with these conditions gradually developing further east across south central Kansas. Widespread rain/rain showers and embedded thunderstorms will also continue across the area along and behind the front. A gradual improvement in CIGS and decreasing coverage in rain is expected during the day on Tuesday. KED && .PRELIMINARY POINT TEMPS/POPS...
