The episode as NWS LUB wrote it up.
An upper level short wave trough moving across the Texas Panhandle combined with low level isentropic lift to create a single isolated thunderstorm. This storm initiated in Collingsworth County and then moved into far northeastern Childress County. A trained spotter reported hail up to golf ball size along US Highway 62 near the Texas/Oklahoma state line.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 20, 5:26 PM CST, 5 hours 1 minute earlier.
Area Forecast Discussion National Weather Service Lubbock TX 626 PM CDT Sat Jun 20 2020 .AVIATION... VFR conditions are expected to prevail the next 24 hours. && .PREV DISCUSSION... /issued 212 PM CDT Sat Jun 20 2020/ SHORT TERM... The best zone for thunderstorm initiation this afternoon has shifted to the south of the forecast area where convergence will be maximized along the outflow boundary that remains from this morning's now-dissipated MCS. Much of the forecast area has been stabilized behind the cool outflow, although clearing of stratocumulus field is resulting in some destabilization of the air mass. However, with lack of any meaningful low level focus and with mid/upper level support well to the north from the northern Texas Panhandle into western Kansas in the form of an upper level short wave trough, it is looking pretty grim for additional thunderstorms chances this evening. Will maintain a slight chance across the southern row of counties given closer proximity to the outflow boundary but will run with a dry forecast for the remainder of the area. Late tonight should see a combination of the aforementioned upper trough combining with some mid level isentropic lift along the Red River to initiate thunderstorms, but that should occur to the east of the forecast area. Sunday will then see the heat return. Without an MCS and/or outflow to affect tomorrow's weather on the mesoscale and with low level veering behind the departing upper level trough, the surface trough/dryline is expected to push eastward toward the Caprock escarpment. Veered low level and lower dew point temperatures should help push temperatures to around 100 degrees for most of the forecast area. There is some signal that an isolated storm or two could develop along the dryline late in the day. That is not out of the question given the expected heat, but confidence not quite high enough to go above 10 percent chance at this time. LONG TERM... Despite a gradual increase in cloud cover over the course of the day on Monday, expect temperatures to reach 100 degrees across the region as drier air encroaches in from the west. Embedded shortwave energy aloft will help push a cold front through the Texas Panhandle during the day Monday and arrive in the South and Rolling Plains by Monday evening. There is a slight chance of showers from general thunderstorms after sunset near Childress and farther east into Oklahoma. Temperatures will cool nicely behind the primary front on Tuesday, with temps falling back down into the 80s for most of us. A stronger shortwave aloft quickly follows reinforcing cooler air for the remainder of the week, while decent moisture return from the Gulf of Mexico is mostly undeterred. A Wednesday dryline in eastern New Mexico will retreat farther west by late afternoon putting the best chances for convection mostly west of the I27 corridor by late afternoon and evening. Severe potential seems low, with lack of wind shear being at least one limiting factor. Temperatures are expected to be at, or slightly below normal through midweek until next weekend. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 51
