The local office's own words before the first event, 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 the first event at Aug 29, 1:08 PM CST, 1 hour 58 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 208 PM CDT Thu Aug 29 2024 .KEY MESSAGES... - Isolated to scattered (15-30%) showers and thunderstorms this afternoon. - More widespread showers and storms (>50%) tonight. - Temperatures fall back to seasonal normals for the rest of the forecast. Much lower humidity will be more noticeable though. && .DISCUSSION... Issued at 208 PM CDT Thu Aug 29 2024 It's another hot and humid afternoon today with temperatures climbing into the middle 90s. Dewpoints persist in the upper 60s to lower 70s, resulting in uncomfortable humidity levels and aiding the development of moderate to extreme instability across the area. Forecast soundings show convective inhibition eroding between 19-20Z with subsequent shower/ storm development. Forecast soundings also show an inverted-V sounding and with ample dry air aloft as well, will support downdraft CAPE values in the 1000-1200 J/kg. This is not quite as a strong as the other day when storms affected the region with significant downburst winds but it's close and as a result, storms could produce strong to possibly severe wind gusts. Coverage of this activity will begin to wane with loss of daytime heating, generally after 00Z this evening. Focus will then shift to the convection moving into the area tonight associated with the cold front. Potential instability will weaken considerably as the front moves into the area and with weak shear the potential for severe weather looks low. But can't rule out some potential for strong winds and small hail. Coverage of the overnight activity will be greatest across northwestern MO and northeastern KS where we have 65-85% PoPs. But as this area pushes south and east with time, coverage lessens due to weaker forcing and instability. The front moves just south of the area by Friday afternoon. This may lead additional scattered showers and storms in our southern zones through the day Friday. With the exception of the NAM, instability looks modest with weak shear expected. So can't rule out a strong storm or two in our southeastern zones but otherwise, the threat of severe weather looks rather low. Cooler conditions, thoough really just trending closer to normal, are expected for the remainder of the forecast. The weather pattern looks quiet as well as high pressure settles into the central and northern Plains behind the system affecting the region currently. So from Saturday afternoon through Thursday, we have have a dry forecast going with highs generally in the low 80s and lows in the upper 50s to lower 60s. While those temperatures are considerably cooler than what we've experienced recently, it will be the cooler dewpoints in the 50s to lower 60s that will be especially noticeable. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1208 PM CDT Thu Aug 29 2024 Isolated to scattered showers and storms are possible this afternoon across eastern KS and western MO. Model forecast soundings suggest convective inhibition is lost in the next 2-3 hours. Ensemble probabilities of precipitation >0.01" also suggest a 20-40 percent chance for activity this afternoon. Given this, have added some mention of storms to all sites from 20Z and 00Z. With loss of daytime heating, this activity wanes and the focus then shifts to the more widespread activity associated with a cold front moving into the area during the overnight hours. Timing of this activity looks similar to the previous forecast. Tomorrow, ceilings are likely to become MVFR with bases around 1500 ft AGL developing/ advecting into the area behind the cold front. && .EAX WATCHES/WARNINGS/ADVISORIES... MO...None.
