What forecasters said that day

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

NWS Topeka, KS wrote its last area forecast discussion before this heat advisory went out at Aug 23, 12:12 PM CDT, 2 hours 49 minutes earlier.

...Update to aviation forecast discussion...

.DISCUSSION...
Issued at 344 AM CDT Mon Aug 23 2021

A warm night across the area, with temperatures still in the mid to
upper 70s as of 3 AM. Across north-central Kansas, a few storms have
made it into Republic County and the vicinity, but have quickly
weakened as they moved into stronger capping. Showers and weak
storms in this area should continue for a few more hours before
finally dissipating. The shortwave trough over the Dakotas that
helped develop these storms will keep moving off to the northeast,
allowing upper ridging over the Southern Plains to expand northward.
A steady south wind will help the boundary layer mix deeper than
yesterday, so expecting higher temperatures but lower dewpoints.
There is some uncertainty as to just how low dewpoints can mix out
to, but they should be a bit lower by afternoon compared to the
low/mid 70s they are now. Despite some lingering uncertainty in the
dewpoints, heat indices of around 105 are likely across much of the
area. Have even expanded the heat advisory a bit farther west along
I-70 corridor.

The synoptic pattern over the region will change little over the
next week. The upper ridge to the south will continue to gradually
expand northward, while any weak disturbances in the flow stay well
to the north. Southerly flow will continue at the surface, to the
south of a quasi-stationary boundary across Nebraska. As such, warm
temperatures will continue at least into the weekend. Tuesday and
perhaps Wednesday/Thursday will see temperatures approach triple
digits towards central Kansas. Here, deeper mixing is likely closer
to the 850 mb thermal ridge axis. Even farther east, most locations
should be in the mid to upper 90s again. Dewpoints will have the
opposite pattern - higher in the east and lower in the west. This
should result in heat indices in the 100-105 degree range each day.
Still will wait to get a bead on how the boundary layer behaves
today before issuing for future days, but additional heat products
will likely be needed for later this week.

Turning towards precipitation, only small chances for showers and
storms will be present through the end of the work week. These
chances will be dependent on evening convection developing along the
quasi-stationary boundary in Nebraska and moving southeastward into
the area overnights. Similar to last night, the more organized
storms can become across Nebraska, the more likely they will survive
long enough to produce some rainfall across northern Kansas. Without
any storm organization (i.e. either strong cold pools and/or MCV
development) increasing capping to the south would quickly kill off
any convection moving into the area. Overall, continue to only keep
PoP in the 10-30 percent range each night through Friday.
Included slightly higher PoP for the weekend, as there is
reasonable agreement in guidance on a slightly stronger upper
trough moving through the Northern Plains.

&&

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1212 PM CDT Mon Aug 23 2021

VFR conditions will persist. Minor gusts still expected at times
during daytime mixing and a moderate diurnal low-level jet
developing around 05Z still looks veered enough for low-level wind
shear inclusion.
