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 28, 2:30 PM CDT, 3 hours 19 minutes earlier.

Area forecast discussion, Aug 28, 2:30 PM CDT, 3 hours 19 minutes before
Area Forecast Discussion
National Weather Service Wichita KS
230 PM CDT SUN AUG 28 2016

.SHORT TERM...(This evening through Wednesday night)
Issued at 230 PM CDT Sun Aug 28 2016

Precip chances/convective trends remain the main challenge the
next few days. Diurnal convection initiated a bit earlier this
afternoon where MLCAPE values have already exceeded 2200 j/kg
along and southeast of the turnpike. Deep layer shear is even
weaker than yesterday, so would expect a continued northward
drift/propagation driven by storm downdrafts/outflows, which
would allow some convection to spread across south central
and central Kansas late this afternoon into early evening. Some
convection could linger or redevelop across the I-70 corridor
of central Kansas overnight with diminishing PoPs across the
rest of the forecast area. Little change is expected into Monday
with mainly diurnally driven convection in the afternoon so will
hold with slight to modest chance PoPs. Remnants of the upper
low spinning over the southwest CONUS still looks to emerge as
a weaker low or shear axis as it migrates across the central
Plains Tuesday into Wednesday. The low level flow will gradually
back to a mean easterly component with weak to modest westerly
flow aloft. The moist and unstable airmass will remain in place
giving a slight up-tick to precip/convective chances during the
mid-week periods. Increased clouds and the somewhat cooler
easterly component flow will result in temperatures several
degrees below climo by Wednesday.

Darmofal

.LONG TERM...(Thursday through Sunday)
Issued at 230 PM CDT Sun Aug 28 2016

The remnant trof or shear axis is expected to weaken further
or shift southeast of the area later in the week under the mean
upper ridge across the Plains. Somewhat drier air advecting
into the area should limit or mitigate precip chances until
the weekend with temperatures gradually warming again closer to
climo.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1223 PM CDT Sun Aug 28 2016

Main aviation concern will be storm chances this afternoon and
early evening.

Storms have developed over southeast KS earlier than the last few
days as low level moisture is slightly higher. With very little
mid/upper flow, these cells have very little movement. Main
concern with afternoon storms will be very heavy rainfall and wet
microburst winds. At this point feel KCNU has the best shot at
storms this afternoon. Should see an overall decrease in activity
after sunset.
