091 AWUS01 KWNH 272053 FFGMPD MOZ000-OKZ000-KSZ000-280250- Mesoscale Precipitation Discussion 0184 NWS Weather Prediction Center College Park MD 452 PM EDT Sat Apr 27 2024 Areas affected...northern Oklahoma, southern through eastern Kansas, western Missouri Concerning...Heavy rainfall...Flash flooding likely Valid 272050Z - 280250Z Summary...Flash flood potential will continue through 03Z as an intense cluster of convection results in training/repeating cells across the discussion area. Areas of 3-6 inch rainfall totals are expected, and locally significant impacts are possible. Discussion...A cluster of intense thunderstorms continue to train/repeat across north-central Oklahoma currently. MRMS rain rates of 1-2.5 inch/hr rain rates continue to be detected near Ponca City and Enid over the past hour, and 3-5 inch totals have been noted from Enid southwestward toward Roger Mills County over the past 12 hours. South of the MCS, a strongly unstable, weakly capped airmass exists, and strong southerly flow (that will only increase through 03Z) will maintain convergence along the southern flanks of ongoing convection, supporting redevelopment over time generally along an axis from Enid, OK to near/north of Pittsburg, Kansas. Additionally, forcing for ascent associated with a shortwave trough over the Texas South Plains is expected to impinge on a dryline near the western OK/TX border region and aid in redevelopment of thunderstorm activity in west-central OK that should move east-northeastward across the discussion area through the evening. In summary, an axis of training/repeating cells appears likely to develop across the discussion area and produce occasional periods of 2 inch/hr rain rates (and 3-6 inch rainfall totals - locally higher). These rainfall totals could result in significant impacts especially in sensitive/low-lying areas. FFG thresholds are relatively low in southeastern Kansas/western Missouri (around 1 inch/hr), further supportive of an eventual flash flood threat in that vicinity.
