What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Aug 2, 4:10 AM CDT, 1 hour 20 minutes before
Area Forecast Discussion
National Weather Service Wichita KS
410 AM CDT Fri Aug 2 2019

.SHORT TERM...(Today through Saturday night)
Issued at 404 AM CDT Fri Aug 2 2019

Storms overnight have developed along and ahead of a 850-700mb
baroclinic zone. A southerly low level jet continues to enhance
moisture transport and WAA over Central and South Central KS.
These storms have been efficient rain makers due to PW values
range from 2 to 2.3 inches. The local PW maxima is sitting over
portions of east Central KS. GFS/NAM/RAP continue to show an
enhanced area of WAA and moisture transport extending into mid
morning and even into the afternoon. Thus, scattered storms will
be possible throughout the day today.

Given continued threat of rainfall and where the main access of
convection set up overnight, opted to add Butler, Marion, and
Chase counties to the ongoing flash flood watch. Also trended high
temps down a shave from the previous forecast given increased
cloud cover expected from lingering overnight convection.

A similar overnight convection scenario is possible again tonight
into Saturday morning. A weak mid level low will be pushing south
through the CWA while strong 925-800mb moisture pushes in from
the south. Looks like shear will be limited again to the 25-35kt
range. Models suggest the best shear upwards of 50kts will be
located just south of the CWA. Expect storms to be strong and
can't rule out a severe storm or two if the shear profile ends up
slightly better than forecast. PW values 2 to 2.3 will again
overspread the CWA thus storms that do develop will have ample
flash flood potential.

.LONG TERM...(Sunday through Thursday)
Issued at 404 AM CDT Fri Aug 2 2019

We will turn drier Saturday evening through the extended period. A
ridge will remain in the vicinity throughout the extended leaving
the upper pattern in a northwesterly flow regime. Expect a slight
warming trend each day throughout the extended ending with
seasonable temperatures in the low 90s for the work week. Late in
the period a slight chance of showers/storms will be possible in
the overnight hours Wednesday and Thursday however confidence in
coverage remains low at this time.

&&

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1218 AM CDT Fri Aug 2 2019

Combo of warm air advection and moisture transport should support
upscale development of storms across central KS overnight. This
will likely impact KSLN, KRSL and could clip KGBD, KHUT and KICT.
KCNU is more likely late tonight as storms roll southeast.
Confidence is lower how storms/precip will play out during the
day. Some increase is probable in the afternoon and evening as
front pushes through. Some chances for mvfr ceilings both this
morning and post frontal in the moist upslope low level flow.
