The episode as NWS AMA wrote it up.
The combined Oklahoma and Texas Panhandles saw quite a bit of moisture return to the area going into the 12th. On both the 12th and the 13th, the combined Panhandles saw widespread rain and thunderstorms across the area. On the 12th some of the storms produced hail up to the size of nickels. Strong winds upwards of 73 mph were measured and several reports of wind damage were made. On the 13th the second round of storms produced hail up to 1.5 in diameter and gusts measured up to 75 mph. Some flooding also occurred on the 13th in Wheeler County.

NWS Amarillo, TX wrote its last area forecast discussion before the first event at Aug 12, 12:48 PM CST, 3 hours 2 minutes earlier.
Area Forecast Discussion National Weather Service Amarillo TX 148 PM CDT Sat Aug 12 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM ... (This evening through Sunday night) Issued at 147 PM CDT Sat Aug 12 2023 Subtropical moisture will continue to be brought northward over the Panhandles through Sunday night between high pressure to our east and low pressure to our west. This moisture will continue to interact with several upper level disturbances moving through the flow and several boundaries on the surface to help bring showers and thunderstorms to the region through Sunday night. An outflow boundary from southern Union County, NM to the northern Low Rolling Plains will help focus showers and thunderstorms this afternoon. More thunderstorms are expected to move this way from southeast Colorado and northeast New Mexico. Any of these storms may become severe, however, the best wind shear and instability will be found across the Oklahoma Panhandle and the northern Texas Panhandle. These storms will also be efficient rain producers, so will have to watch for any flooding. On Sunday, an upper level disturbance on the bottom side of an upper level low moving through the northern plains will help to form more showers and thunderstorms across our area. Upper level diffluence combined with instability and moisture will help to maintain the showers and storms. Showers and thunderstorms are expected to continue into Sunday night aided by a southward moving cold front. && .LONG TERM ... (Monday through next Friday) Issued at 147 PM CDT Sat Aug 12 2023 A nice cool start to the work week will quickly change back to the Summer heat by mid week. Outside of some lingering showers/storms on Monday morning, mostly dry conditions are expected through the end of the work week. A surface cold front should be well south of the Panhandles by sunrise on Monday morning. In its wake, cloud cover should remain over portions of the area along with some lingering showers/storms for at least a few hours behind the front. H850 temperatures may remain in the mid teens C throughout the day which would lead to very comfortable temperatures in the 70s and perhaps low 80s for highs on Monday. The 12/13z NBM probabilities for less than 80 degree highs continue to slowly increase for the entire area. In general, the entire area has at least a 60 percent chance outside of the far southeastern TX Panhandle which has around a 40 percent chance of remaining below 80 degrees. Upper level ridging becomes elongated towards the northwestern CONUS Tuesday and beyond which leads to high pressure over the Southern High Plains. Steadily increasing temperatures are expected Tuesday and beyond along with mostly dry conditions. High temperatures should return to the 90s and triple digits by Wednesday afternoon and will likely remain that way through the rest of the work week. Muscha && .AVIATION... (18Z TAFS) Issued at 1212 PM CDT Sat Aug 12 2023 Thunderstorms will be possible at all TAF sites this afternoon or evening. Some of the storms may become severe with large hail and damaging winds the main threats. Thunderstorms should move east of the TAF sites late this evening. However, more showers along with isolated thunderstorms may linger through sunrise Sunday morning, but confidence is not high enough to mention any TSRA at any given TAF site after midnight. Winds will remain generally around 10 knots or less outside of thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
