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 Kansas City, MO wrote its last area forecast discussion before this heat advisory went out at Aug 8, 12:24 PM CDT, 2 hours 17 minutes earlier.
Area forecast discussion, Aug 8, 12:24 PM CDT, 2 hours 17 minutes before
AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 1224 PM CDT Sun Aug 8 2021 .Discussion... Issued at 206 AM CDT SUN AUG 8 2021 Key Messages... - Showers and thunderstorms will persist across portions of the region through the early morning hours. The overall severe concern has decreased considerably. - A few strong to severe thunderstorms are possible Sunday Afternoon. Primarily across north into west central and central Missouri. Damaging wind gusts are the greatest concern with any convection that develops at this time. - Hot and humid conditions will continue into early this week. Monday will be the hottest, with heat index values between 100 to 105 F across much of the region. Overnight lows will also remain in the mid to upper 70s from this morning through Tuesday morning. Detailed Discussion... Enhancement due to the low level jet intersecting the outflow from a cluster of storms moving east out of southeast Nebraska into northwestern Missouri late Saturday night resulted in a window of vigorous convective updrafts. This cluster had a history of producing isolated strong to damaging wind gusts. Through 1 AM, with the shift of the outflow and surface trough eastward and decreasing instability, strong to severe wind concerns have ended. Isolated thunder and breezy conditions remain possible through the early morning. Farther south along the surface trough, convection ongoing across eastern Kansas maintained a steady state, gradually decreasing, while continuing to move toward and across the MO/KS border. From current conditions and latest short range solutions, scattered thunder and showers will continue to linger through the early morning as they slowly advance eastward. Overall, lack of focused forcing and instability should result in a continued downward trend as it moves eastward. Sunday, some isolated lingering convection is probably going to hang on through daybreak across north central Missouri, perhaps as far west as west central MO/eastern KS depending on the orientation of the surface trough across the region. Overall, even with influence from convective debris in the morning, we should anticipate a recovery period, with support from the upper trough still residing over the region. Anticipate an axis of increasing instability developing across the region with ample mid-layer flow. CAMs are in decent enough agreement to suggest convective initiation along the boundary around mid-afternoon, likely just east of the KC Metro and northeast. Primary concerns will be strong to damaging wind gusts, frequent lightning, and pockets of isolated downpours with the strongest storms. Activity will shift east and decrease through the late evening hours. Monday is still looking to be the hottest day of the week. Modest brief ridging will set up across the plains, with a sufficient thermal ridge developing off the southern High Plains into the Mid- Missouri River Valley. Still anticipating afternoon highs pushing the upper 90s and heat index values between 100 to 105 F. Tuesday will be hot and humid, but an open short wave will introduce a chance for showers and thunderstorms, this may keep heat index values at bay with increased cloud cover. However, humidity is such that heat index values may easily approach the lower 100s F. Regardless, overnight lows from this morning (Sunday) through midweek will continue to hover in the mid to upper 70s, not giving much of a reprieve from the heat overnight. Will hold of on a heat advisory at this time for Monday, allowing the Sunday day shift to lock in on the details. Precipitation chances continue into Wednesday, with the remainder of the week rather quiet, but remaining warm. && .Aviation...(For the 18Z TAFS through 18Z Monday Afternoon) Issued at 1215 PM CDT SUN AUG 8 2021 VFR conditions are still expected to continue through the afternoon hours into the evening. There is still a slight change for isolated strong to severe thunderstorms after 20Z through 00Z for our terminals, with IXD having the better chance to see isolated storms later in the evening. If any storms do affect our terminals, main risks include gusting winds, frequent lightning, and heavy rainfall. Quiet conditions and calming winds can be expected by tonight. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...Kurtz Aviation...Klaus

Another round of storms is expected this afternoon and evening, along/east of I-35. Damaging winds are the main concern but could also see some smaller hail. Localized flash flooding is also possible and can't completely rule out a tornado.

High temperatures are forecast to be in the low to mid 90s with heat indices between 100-110 degrees. There is some uncertainty we will reach those values on Tuesday though due to storm chances and the potential for increased cloud cover.
