What happened
The episode as NWS AMA wrote it up.
Diurnally driven convection from the high terrain off of New Mexico and Colorado worked their way southeastward during the afternoon hours. Across the far western combined Panhandles, environment of CAPE/MUCAPE of 1000-2000 J/Kg in-conjunction with easterly surface flow and moisture pool behind the passing cold front. This set the environment to support thunderstorms that worked their way east from NM/CO. An isolated cell did make it into the far western TX Panhandle with half dollar size hail reported. Convection then waned toward the evening hours with the loss of daytime heating.

Area forecast discussion, Jun 30, 4:52 PM CST, 2 hours 32 minutes before
Area Forecast Discussion National Weather Service Amarillo TX 552 PM CDT Fri Jun 30 2017 .AVIATION... 00Z TAF Cycle VFR conditions are expected at all three TAF sites through 05Z to 08Z Saturday except in and near showers and thunderstorms where MVFR visibilities and ceilings are possible along with strong and erratic winds from thunderstorms. After 05Z to 08Z Saturday, MVFR to possibly IFR conditions are expected as low cloudiness increases at the Dalhart and Amarillo TAF sites. The Guymon TAF site should see VFR conditions through 00Z Sunday. The Dalhart and Amarillo TAF sites should see VFR conditions return after 19Z to 21Z Saturday. Northeast to east winds 10 to 20 knots with some gusts near 25 knots will diminish to around 5 to 15 knots at all three TAF sites after 08Z to 10Z Saturday and will become east to southeast after 19Z to 21Z Saturday. Schneider && .PREV DISCUSSION... /Issued 426 PM CDT Fri Jun 30 2017/ DISCUSSION... Not many changes have been made to the forecast, other than to attempt to refine timing of thunderstorm chances through Sunday. For tonight, moist easterly upslope flow in a moderately unstable atmosphere will promote the potential for thunderstorm development, mainly across western and southern sections this evening, closer to the frontal boundary where instability will be higher. Saturday should be mostly dry, with a slight chance of showers and thunderstorms across southern sections. Thunderstorm chances increase Saturday evening and Saturday night, as a shortwave trof assists in thunderstorm development in northeast New Mexico, with a good opportunity for thunderstorms to spread east and southeast across the Texas and Oklahoma Panhandles. Severe thunderstorms with hail around one inch in diameter and gusts to around 60 MPH could occur. Brief heavy rains will also be possible. Thunderstorms will be possible Sunday afternoon and Sunday evening across all sections, with eastern sections being favored, owing to expected orientation of instability. Mainly nocturnal thunderstorms expected Monday night through Wednesday night, primarily across eastern sections, which should be the most removed from strengthening mid-level ridge.
