409 AWUS01 KWNH 280816 FFGMPD ILZ000-MOZ000-ARZ000-OKZ000-KSZ000-281415- Mesoscale Precipitation Discussion 0193 NWS Weather Prediction Center College Park MD 415 AM EDT Sun Apr 28 2024 Areas affected...Much of Southwest and Central MO Concerning...Heavy rainfall...Flash flooding likely Valid 280815Z - 281415Z SUMMARY...Sacttered areas of flash flooding will be likely through the mid-morning hours across central and southwest MO as heavy showers and thunderstorms impact the region. DISCUSSION...Radar imagery shows a broken QLCS continuing to impact the broader Lower MO Valley, with organized areas of showers and thunderstorms continuing to produce heavy rainfall rates of as much as 1 to 1.5 inches/hour. Areas of cell-training are currently situated over west-central MO and this is also in an area where stronger low-level convergence remains focused along with a pool of instability characterized by MUCAPE values of 1000 to 1500 J/kg. An MCV is becoming apparent in radar imagery over southeast KS and this will be advancing off to the east-northeast over the next few hours into central and southwest MO. This energy coupled with a southerly low-level jet of 40 to 50 kts aiming into a west/east oriented outflow boundary/trough axis across central MO should tend to maintain a formidable threat of additional convection persisting through the early to mid-morning hours with some additional concerns for cell-training. There should tend to be a bit more of a progressive character to the remaining QLCS activity over southern MO. Additional rainfal totals of as much as 2 to 4 inches will be possible with the heaviest rainfall likely in close proximity to the aforementioned outflow boundary over central MO. Given the sensitive/wet soil conditions and additional rains, there should be at least some scattered areas of flash flooding going through the early to mid-morning hours.
