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.

NWS Wichita, KS wrote its last area forecast discussion before this special weather statement went out at Aug 11, 6:45 PM CDT, 2 hours 8 minutes earlier.

Area forecast discussion, Aug 11, 6:45 PM CDT, 2 hours 8 minutes before
Area Forecast Discussion
National Weather Service Wichita KS
645 PM CDT THU AUG 11 2016

.SHORT TERM...(This evening through Saturday night)
Issued at 307 PM CDT Thu Aug 11 2016

Main forecast concern for the next 24 hours will be the cold front
to push through tonight into Fri morning. This front currently
extends from northeast Nebraska into west central KS and is
continuing to push south. Storms are expected to develop soon over
west central KS as the right entrance region of a jet max slides
over the area. In addition, increased surface convergence should
also lead to development prior to 00z. Convection is expected to
increase in coverage this evening as 850-700mb moisture transport
ramps up along with most of the area under diffluent flow aloft.
While widespread severe storms are not anticipated, can't rule out
a wet microburst and small hail with any storm. With PW values
remaining around or just over 2", very high rainfall rates will be
likely with any shower or storm tonight, so wouldn't be shocked to
see a few flood warnings issued.

The good news regarding prolonged flooding is that the front will
be fairly progressive as it pushes south, before stalling out
over OK/AR Fri through the weekend. So for Fri, the better precip
chances will be over the southern portion of the forecast area
with only SE KS holding onto POPs for Fri night into Sat. The
passage of the front will return the area to more seasonal temps
with highs in the mid and upper 80s expected for Fri through the
weekend.

.LONG TERM...(Sunday through Thursday)
Issued at 307 PM CDT Thu Aug 11 2016

The next feature to keep an eye on will be a tropical impulse
that is expected to track north out of the se TX/LA Gulf coast
area. Both the GFS and ECMWF lift this energy north over the
arklatex region Sat night and into far eastern OK/AR by Sun
evening. This should enhance the areal extent of rainfall along
the stalled surface front for Sun night through Mon night. While
it still looks like the more significant rainfall will occur from eastern
Ok into southern MO and AR, cant rule out that some of it may clip
far se KS. Temps should remain fairly comfortable through these
extended periods with highs at or slightly below seasonal
averages.

&&

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 644 PM CDT Thu Aug 11 2016

Main aviation issues are timing and magnitude of convection
during this period. Strong-severe storms anticipated throughout
the evening at KRSL-KSLN-KGBD-KHUT with storms potentially waning
a bit later tonight with loss of surface heating and in absence of
strong baroclinic zone in mid levels. Current convection is ahead
of cold front, which will slowly move into the area late
tonight/tomorrow morning. Some MVFR ceilings possible in the
vicinity of front in central KS. -Howerton
