The episode as NWS ICT wrote it up.

Area Forecast Discussion National Weather Service Wichita KS 1234 PM CDT Thu Aug 9 2018 .UPDATE... Issued at 1233 PM CDT Thu Aug 9 2018 Will likely see isolated to widely scattered hit-or-miss slow-moving thunderstorms once again this afternoon and evening, mainly south of a Great Bend to Salina line, as a subtle mid-level trough and associated surface trough/wind shift settles south amidst an unstable and weakly capped airmass. Greatest coverage should be across southeast Kansas underneath slightly cooler mid- level temperatures. Despite weak winds aloft, modest directional shear may promote just enough storm organization for a few strong storms capable of pea-dime size hail and 50 mph winds, but widespread severe weather is unlikely. Additionally, slow storm movement could promote small pockets of intense rainfall rates. Activity should tend to dissipate around or shortly after sunset. && .SHORT TERM...(Today through Saturday night) Issued at 152 AM CDT Thu Aug 9 2018 Dry weather conditions will prevail across the region today as subsidence overspreads the area in the wake of the upper level PV wave. Meanwhile current early morning water vapor satellite imagery shows an another upper level PV wave over Montana which will continue to dive southeast and move into Kansas during the afternoon on Friday. This could generate widely scattered showers and storms during the afternoon/evening hours across the eastern half of Kansas. Strong/severe storms look unlikely given weak wind shear aloft. Dry weather looks to be in store for Saturday with Friday's upper level wave moving south of Kansas. .LONG TERM...(Sunday through Wednesday) Issued at 152 AM CDT Thu Aug 9 2018 Confidence is now increasing for this period as models remain consistent with development of an upper level low pressure system over the Texas panhandle on Sunday. They all show a very slow northeast migration of the upper level low pressure to central Kansas by Tuesday night. In addition, a much richer precipitable water airmass looks to stream northward associated with this slow moving system. A two to three day period of strong/rich moisture transport could result in a couple episodes of heavy rainfall and possible flooding across the region. Especially during the Monday/Tuesday time frame. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1233 PM CDT Thu Aug 9 2018 Will likely see isolated to widely scattered hit-or-miss slow-moving thunderstorms once again this afternoon and evening, mainly south of a GBD to SLN line. Greatest coverage should be across southeast Kansas, including CNU. Strongest activity will be capable of pea-dime size hail, 50 mph winds, frequent lightning and pockets of heavy rain, but widespread severe weather is unlikely. Activity should tend to dissipate around or shortly after sunset. Another chance for isolated to widely scattered thunderstorms arrives once again for Friday. && .PRELIMINARY POINT TEMPS/POPS...
