The episode as NWS LUB wrote it up.
A mesoscale convective system (MCS) developed over the Texas Panhandle and moved east during the late afternoon and evening hours of the 22nd. However, a very hot and deeply mixed atmosphere had developed from east-central New Mexico into the extreme southwestern Texas Panhandle creating an unstable atmosphere. Isolated thunderstorms developed initially in eastern New Mexico before moving into the extreme southwestern Panhandle. A couple of these storms became severe while in Parmer County producing severe winds and quarter size hail.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 22, 5:45 PM CST, 35 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 645 PM CDT Fri Jun 22 2018 .AVIATION... The biggest question is whether or not convection currently moving across the Texas Panhandle will affect any of the TAF sites later this evening. The bulk of the thunderstorms should stay north of the terminals, though activity from Friona to north of Clovis could come close to KPVW and KCDS, if it can maintain itself. This is less than certain, so have kept any mention out of the TAFs for now, but will watch closely and amend as necessary. Outside of any storm impacts, VFR should prevail through this evening and southerly winds should gradually weaken, particularly after sunset. Following a thunderstorm complex moving by to our north, an outflow aided front should move through the terminals late tonight into Saturday morning, though the exact timing of the FROPA is tough to pinpoint as it will largely depend on how strong a push it gets from the convective outflow. Regardless, lighter northerly to easterly winds should overspread the terminals by Saturday afternoon. There could even be a period of MVFR ceilings early Saturday, though confidence in this is too low to include explicitly in the TAFs attm. && .PREV DISCUSSION... /issued 244 PM CDT Fri Jun 22 2018/ DISCUSSION... Remnants of an outflow boundary from a complex that pushed through OK through the morning hours is currently bisecting the FA from northwest to southeast. While there is very evident surface convergence it is no match for overhead subsidence. CU has tried to develop along the boundary through the morning but has since given up. Our chances for rain are not fully gone, however, as at least parts of the FA could see showers and thunderstorms later this evening as convection develops over the Raton Mesa and pushes southeastward under the influence of northwesterly flow aloft. These storms could push as far east as the southern Rolling Plains by the mid to late evening as a shortwave moves overhead allowing heights to fall over much of the FA. A "cold" front will follow in overnight into tomorrow and will help lower highs tomorrow afternoon by a couple of degrees (low to upper 90s instead of low 100s across many portions of the FA). Southerly surface flow will return fairly quickly by early Sunday as a surface low develops over southeastern CO/northwestern NM ahead of upper troughing pushing southward across the foothills of the central Rockies. With this temps will once again rise to the century mark. Another weak cold front will follow by Monday morning. This front will initially be dry. Some convection will be possible across its remnants late Monday into early Tuesday as surface winds quickly return to the southeast allowing moisture return to interact with what is left of the frontal boundary. After Tuesday heights are expected to rise as high pressure dominates. How much the high affects us is in question as the ECMWF builds the high over the southern half of the CONUS with a trough digging southward across the west coast by late week while the GFS has a much weaker ridge with upper flow being out of the southwest. The GFS solution would be more friendly in terms of precip chances and high temps while the ECMWF would only spell hot conditions mid to late next week. && .LUB WATCHES/WARNINGS/ADVISORIES...
