The episode as NWS OUN wrote it up.

Area Forecast Discussion National Weather Service Norman OK 430 AM CDT Sun Jul 16 2023 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 357 AM CDT Sun Jul 16 2023 The storm complex that moved southeast across the Texas panhandle is turning left and now has a more eastward component of motion as it moves into our north Texas counties. In addition, there are also some weak developing showers from south of Elk City to west of Ardmore, which some of the models had hinted may develop with perhaps some weak isentropic upglide on the 305K surface. First period POPs are tricky since the primary complex seems to be farther south than many models projected, but the developing showers in southern Oklahoma may still give some precipitation farther north. For now, have kept the highest POPs in the far south associated with the complex, but keep 20-30s farther north with the other development. Will watch trends and make adjustments based on movement of the complex, and how widespread the new development becomes. This activity will continue to move generally east and likely weaken with time, but chance POPs still linger in the southeast into the afternoon. Meanwhile, a mid-level wave moving from the northern Plains into the Midwest today will help push a surface cold front south into Kansas. There is some potential for storms developing on the front to make a move toward north central Oklahoma this evening. Much of the activity may stay northeast of the forecast area, but there is enough potential for low POPs and the marginal risk of severe storms as per the latest SPC outlook. && .LONG TERM... (Monday through Saturday) Issued at 357 AM CDT Sun Jul 16 2023 The GFS is quite aggressive with QPF into Monday across the I-35 corridor, but looks to also be suffering from convective feedback. The potential for showers/storms Monday is non-zero as even the other models have some QPF signal to our east. Do not have POPs high enough to mention yet, but it will be worth watching the trends. After this, the mid-level ridge builds into the Plains, cuts us off from precipitation chances and brings a return of hot weather for a couple of days. The ridge re-orients and/or weakens some toward the end of the week to allow some storm chances, as a series of shortwaves move from the central Rockies over Kansas or Oklahoma. && .AVIATION... (12Z TAFS) Issued at 428 AM CDT Sun Jul 16 2023 Mostly VFR conditions are expected through the TAF period. Thunderstorms could impact KSPS, dropping visibilities down to IFR conditions. These storms should move out by mid morning. Otherwise, winds will pick up out of the south, with mid to high- level clouds overspreading much of the area. && .PRELIMINARY POINT TEMPS/POPS...
