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 15, 3:11 PM CDT, 1 hour 49 minutes earlier.

Area forecast discussion, Aug 15, 3:11 PM CDT, 1 hour 49 minutes before
Area Forecast Discussion
National Weather Service Wichita KS
311 PM CDT Sun Aug 15 2021

.SHORT TERM...(This evening through Tuesday night)
Issued at 309 PM CDT Sun Aug 15 2021

Forecast highlights the next 7 days:

* Periodic thunderstorm chances the next several days.

* Near to slightly below normal temperatures the next several days.

MCV currently spinning slowly south across central KS amidst a moist
and weakly capped airmass will be the focus for isolated to widely
scattered hit-or-miss thunderstorms through the evening, mainly
along and west of the Flint Hills corridor. Modest mid/upper
northwesterly flow may support just enough deep layer shear for some
weak storm organization and associated marginal strong to severe
storms. Main threats with the strongest activity will be dime-
quarter size hail, 50-65 mph downburst winds, and locally heavy
rainfall. Widespread severe weather is not expected.

Thinking later tonight, additional thunderstorm activity could move
into central KS from the north, as a lobe of shortwave energy
approaches from the north. Thinking these chances will move/expand
southeastward on Monday, encompassing much of the region given the
upper forcing and moist/weakly capped airmass. Not expecting
widespread coverage, but more of the isolated to widely scattered
hit-or-miss variety. Like today, combination of instability/shear
could support a few strong to marginally severe storms, along with
locally heavy rainfall.

Much of the same for Tuesday...lingering weak upper energy and
associated cooler temperatures aloft amidst a moist/weakly capped
atmosphere will support additional isolated hit-or-miss
showers/storms. Went against the lower PoP NBM load and inserted
slight chances across the whole forecast area, although suspect
slightly higher shower/storm chances may focus further east across
southeast KS.

.LONG TERM...(Wednesday through Sunday)
Issued at 309 PM CDT Sun Aug 15 2021

Unsettled pattern shower/thunderstorm-wise continues mid week, as
additional subtle mid/upper energy progresses over Mid-America
amidst increasing precipitable waters. These chances continue
through late week, as an unseasonably strong upper trough progresses
across the western and northern CONUS, dragging a cold front
south/southeast into Mid-America. The ECMWF is a bit more agressive
with the southward push of this front, supporting somewhat cooler
and mostly dry weather by next weekend. However, the GFS and GEM
stall the front across the region, supporting continued muggy
conditions and higher rain/storm chances next weekend.

All-in-all...while isolated occurrences of strong to marginally
severe storms are possible, the potential for widespread severe
weather is low mid week through the weekend. However, increasing
flow aloft associated with the glancing blow of the deep western
CONUS trough may support a slight uptick in severe storm chances
late week into the weekend. Also, pockets of heavy rainfall and
localized flooding are possible through the entire forecast
period.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1217 PM CDT Sun Aug 15 2021

VFR conditions expected through most of the TAF period with light
southeast winds. However, there is a chance of a few storms along
and mainly west of I-135 this afternoon. Additional storms may
move into the area from the northwest tonight. However, there is a
lot of uncertainty in timing and coverage of any storms thus left
specific mention out of TAFs for now. Areas that see storms
tonight could result in MVFR cigs or lower by tomorrow morning.
