What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Sep 1, 3:55 PM CDT, 2 hours 36 minutes earlier.

Area forecast discussion, Sep 1, 3:55 PM CDT, 2 hours 36 minutes before

Area Forecast Discussion
National Weather Service Wichita KS
355 PM CDT Sat Sep 1 2018

.SHORT TERM...(This Evening through Monday Night)
Issued at 355 PM CDT Sat Sep 1 2018

Tonight:
The primary focus remains on thunderstorms that approach severity
over much of Western & part of Central KS where closest to a weak
approaching mid-level shortwave. An area of thunderstorms has been
ongoing over primarily Northwest KS almost all day. Situation may
be complicated by the extensive mid-upper deck cloudiness that has
been inducing inhibition. Regardless greatest thunderstorm chances
would still target Western & North-Central KS as well as Southern
Nebraska where greatest 6-8KM bulk shear (30-40kt) will reside. As
such have kept highest probabilities (~40%) assigned generally to
the 5 northwestern-most counties. MLCAPES 2,000-2,500 J/KG (Per
SPC mesoanalysis) coupled with the increasing bulk shear induced
by the approaching shortwave would no doubt translate into these
areas being at greatest risk for severe convection.

Rest Of Labor Day Weekend:
Thunderstorms capable of heavy rains will gradually increase,
especially across Central KS as weak front settles S/SE toward
these areas. Greatest deep-layer shear remains entrenched from
Western KS to the IA/MN state line & as such from a standpoint of
severity the thunderstorms should behave.

.LONG TERM...(Tuesday through Saturday)
Issued at 355 PM CDT Sat Sep 1 2018

Forecast remains essentially unchanged with heavy rain-producing
thunderstorms have extended stays across the Great Plains. Lift is
lacking, but high octane moisture remains entrenched across nearly
all of the CWA. (Especially Eastern KS.) As such, flooding will
certainly become a concern by mid-week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1236 PM CDT Sat Sep 1 2018

VFR conditions expected to prevail thru the forecast valid period.
Scattered strong to marginally severe convection is expected to
develop and affect central Kansas this evening and may fester
overnight. Diurnally gusty south winds will diminish with sunset.
