NWS Kansas City, MO wrote its last area forecast discussion before the first event at Aug 19, 3:16 AM CST, 1 hour 31 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 416 AM CDT Tue Aug 19 2025 .KEY MESSAGES... - Isolated to scattered showers and thunderstorms early this morning. A few storms may pack strong winds and heavy rainfall. - Heat index values around much of the region reach near to just above 100F. Some areas near Butler and Clinton could briefly see heat index values near 105F. - Additional storms are possible later this afternoon and evening across southern portions of the CWA (I-70/US-50 south) more likely along the I-44 corridor. && .DISCUSSION... Issued at 415 AM CDT Tue Aug 19 2025 A cooler air mass is slowly working its way into the region. Satellite and radar imagery through the night shows a couple mesoscale convective systems around the region, one over northern KS and another over northern IL. Satellite imagery also shows a boundary across west central MO which is likely the boundary between the antecedent hot air mass of the past week and the cooler one that is steadily making its way into the area. Outflow boundaries ejected by the nearby MCS are moving through the area providing just enough lift to initiate some isolated elevated thunderstorms this morning. These storms have been relatively short lived as upper level flow has been relatively weak with just enough instability to initiate storms, but not enough to sustain them. Some storms have been able to harness the instability and build quickly; however, this also leads to them to dissipate quickly. The results in potential downbursts and microbursts winds around 40-50 MPH along with heavy rainfall. The boundary between the hot and cooler air mass will be the primary focus feature for todays weather outlook. This boundary has made it a bit farther south than previous model guidance forecast suggested which shifts the storm potential farther south. The boundary has retreated a little further north with influence from the MCS to the west as well as a weakening upper level ridge extending from eastern OK through WV. The end result is this feature sitting across east central KS and west central MO from around Garnett, KS through Columbia, MO. Solar heating through the day will enhance differential heating across this boundary. South of the boundary, diurnal heating plus southerly flow brings heat indices above 100-105F. The location of this boundary through our southern tier of counties looks to limit the potential for hazardous heat to a small portion of the afternoon. Any clouds or storms that form due to the boundary may also tamper with heat indicies. Heat index values north of the boundary are expected to be lower thanks to weak northerly flow at most all levels. Unfortunately, this flow will not be enough to keep hot and humid conditions away, but it will limit most areas from exceeding 100-102F. Differential heating across this boundary also serves as a catalyst for slight warm frontogenesis and initiate isolated to scattered convection across our southern two tiers of counties. With vertical profiles showing generally weak flow across all levels, it will likely take an outflow boundary or some other catalyst to initiate storms. Like this morning, this will likely keep any storms that form to behave more like pulse storms rather than robust convection. Expected CAPE values around 1500-3000 J/kg show the potential for strong updrafts which could produce a strong storm with heavy rainfall and potentially damaging winds; however, these are expected to be quite short lived; yielding a marginal risk for strong to severe storms later this afternoon. The cooler air mass to the north continues to track southward through the day bringing more seasonal conditions starting Wednesday through the rest of the week. Another wave of cooler air looks to move in towards the weekend bringing our next notable chance of precipitation while also ushering in even cooler temperatures with prospective highs in the mid to upper 70s. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1115 PM CDT Mon Aug 18 2025 VFR conditions through the period. Light and variable winds through the overnight. Mixing will lead to light north-northeast throughout the daylight with few-scattered cumulus near 3K. Outside chance of a thunderstorm or two, but confidence is low so left mention out of the terminals for the time being. && .EAX WATCHES/WARNINGS/ADVISORIES... MO...None.
