What happened

The episode as NWS ICT wrote it up.

An early morning complex of thunderstorms moved across the eastern half of Kansas during the morning hours of August 7th, 2019. This complex left an outflow boundary located over southeast and south central Kansas for the late afternoon into the evening hours. Scattered strong to severe storms developed along this boundary and produced damaging winds gusts. the training and redeveloping storms eventually turned into heavy rainfall producers into the early morning hours of August 8th, with flash flooding reported across southeast Kansas. Rainfall amounts of 3 to 5 inches were common across the region.

What forecasters said that day

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 Aug 7, 5:29 PM CST, 4 hours 23 minutes earlier.

Area Forecast Discussion
National Weather Service Wichita KS
629 PM CDT Wed Aug 7 2019

.SHORT TERM...(This evening through Friday night)
Issued at 330 PM CDT Wed Aug 7 2019

As of early this afternoon, the MCS that made its way southeast
across eastern Kansas this morning continues to push off into
southwest Missouri with a few lingering showers in far southeast
Kansas. Ahead of this feature, GOES-E visible satellite imagery
shows a well defined outflow boundary extending from roughly
Harper County, KS and southeast into Northern Oklahoma north of
the Tulsa metro area. Increasing cumulus development was noted
along and just to the south of this outflow boundary in northern
Oklahoma.

For the rest of the afternoon and evening, as the remainder of the
elevated convection in southeast Kansas exits the forecast area, the
more stable air should dampen any chances of convection across most
areas. As the previous mesoscale discussion mentioned, however, with
increased/significant heating in the vicinity of the outflow
boundary in northern Oklahoma, cannot completely rule out some
convective development along this boundary which has potential to
migrate back northward into the vicinity of southern Kansas. There
is plenty of available buoyancy with MLCAPE in the vicinity of
3500- 4500 J/kg and RAP forecast soundings suggest effective bulk
wind difference of 40-45kts along the southern tier of Kansas
counties over the next several hours. Convective inhibition has
been on a downward trend in the vicinity of the outflow over the
past few hours, and latest radar imagery shows a couple of storms
have already formed in the vicinity of Enid and Ponca City, OK.
Most short term and hi- res guidance favor a dry scenario for
southern Kansas, but think a few storms are certainly possible.
After 00z, convective inhibition significantly increases across
the entire forecast area once again, so although slight chance
pops were maintained in the forecast for the evening and tonight,
it is possible that these are still overdone for most areas within
the forecast area, particularly before 07z or so.

Temperatures have struggled today in the context of convective
activity for much of the morning and early afternoon in southeast
Kansas and portions of south central Kansas that were originally
included in a heat advisory today. As a result, many counties were
removed from the heat advisory early, and latest observations
suggest even those counties that remain (Kingman, Harper, Sumner)
will only reach advisory criteria for a brief time.

Overnight tonight and early tomorrow morning, a similar scenario as
last night/early this morning is expected with a complex of storms
forming in north central and northeast Kansas and then propagating
southeastward across the forecast area. The best chance for higher
precip amounts appears again to be along the Flint Hills corridor
and in southeast Kansas, where a Flash Flood Watch remains in tact
beginning at 01z this evening and lasting through the morning
tomorrow. Much higher rainfall amounts will be possible a little
further northeast of the area, but with precipitable water (PW)
values in excess of 2.0 inches in portions of central and southeast
Kansas, storms will be very efficient rain producers and present a
flood threat. In addition to flooding, with sufficient buoyancy,
moderate mid-level lapse rates, and roughly 40 kts or so of bulk
shear, some storms overnight/early tomorrow morning could be
strong to severe with hail and strong winds as the main threats.

By tomorrow, expect that most of the showers and storms will have
pushed into the southern portions of the area and down into
Oklahoma. However, have maintained POPs throughout the day, as
models hint at another subtle shortwave in the overall synoptic flow
could sustain shower/storm chances throughout the day and into the
evening.

Things should quiet down, at least temporarily, by around midday
on Friday before another shortwave brings more chances of showers
and thunderstorms overnight Friday night and again on Saturday
evening/night.

.LONG TERM...(Saturday through Wednesday)
Issued at 330 PM CDT Wed Aug 7 2019

In the long range, the mid/upper high over the southwest U.S. is
progged to slide slowly eastward across the southern CONUS from
Saturday-Tuesday of next week. A frontal passage looks to continue
the active pattern for the first half of next week, with fairly
decent chances of showers and storms again during the Monday-
Tuesday time frame. Temperatures will be more seasonable, with
afternoon highs averaging in the upper 80s and low 90s each
afternoon Saturday through the end of the period.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 625 PM CDT Wed Aug 7 2019

VFR conditions for all sites except for KCNU where their is a
possibility of a low CIG deck overnight and early tomorrow.
Anticipate VCSH and VCTS for KCNU and KSAL much of the overnight
and morning hours tommorow due to the NW flow aloft and
instability that is in place. Likely seeing another MCS type
system roll through. It is possible this could seep as far south
at KICT, however, I have kept mention out for now. Better TSRA
chances will creep in tomorrow but not confident with timing with
this fcst so I will keep out for now and add with later run.

.DAY ONE...Tonight

A chance for storms capable of heavy rainfall and some severe
weather is expected late this evening and overnight, generally
northeast of a Russell to Wichita to Sedan line. Repeated rounds of
heavy rain may lead to flash flooding and a flash flood watch has
been issued for portions of the Flint Hills and southeast Kansas.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Periodic chances of thunderstorms will remain in the forecast each
day through early next week. Some strong or severe storms with
heavy rain will remain possible through the period. Repeated rounds
of heavy rain may lead to localized flooding concerns. Stay tuned,
as daily thunderstorm chances will continue to be refined with
subsequent forecasts.

Heat indices could climb in the 100-105 degree range across
southern Kansas each afternoon Thursday through early next week.

Hail: Hail three-quarters of an inch or larger, or smaller hail that caused damage, filed with the largest stone measured.
Flood: Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.
Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
