Thunderstorms formed over the higher terrain of eastern New Mexico on the evening of the 20th on the east side of a strong upper level ridge. This thunderstorm activity was decaying by the time it reached the Texas/New Mexico state line early on the 21st but was still able to produce a severe wind gust near Friona (Parmer County).

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, 8:53 PM CST, 2 hours 57 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Lubbock TX 953 PM CDT Tue Jun 20 2017 .UPDATE... A mini MCS moving S-SE across srn Quay and Curry County NM will brush western Parmer and possibly Bailey Counties in the next hour or so. Strong wind gusts will be the main impact from this storm but rain may also move in behind the gust front. We've added some low PoPs in this area through midnight. && .PREV DISCUSSION... /issued 639 PM CDT Tue Jun 20 2017/ AVIATION... VFR conditions are expected to prevail for the next 24 hours. There is a small possibility that the current TSRA activity stretching from northeast NM to southwest KS could eventually approach KPVW and/or KCDS early Wednesday morning. More likely though, outflow from this dying activity could push through one or more terminals, bringing a northerly wind shift - but speeds should remain under 12 kts. PREV DISCUSSION... /issued 422 PM CDT Tue Jun 20 2017/ DISCUSSION... For the first few days, the upper level high off to our west will remain entrenched. This feature is well defined in satellite imagery through the observational data suggests that the flow may be a bit more northwesterly across the panhandle than the models might suggest. By this afternoon, we should see some storms fire across NERN NM though indications suggest that convection should remain NW of our CWFA. Still, a 10-15 shot of storms approaching Parmer county seems reasonable. A minor ripple in the mean flow will skirt well north of the region on Wednesday as a tropical system is progged to approach the upper Texas coast. The currently progged track of the system is expected to have little impact on our weather as we already are under the influence of a respectable high pressure system. Perhaps if it tracks a bit further west, we could see increased subsidence and thus higher temps later this week. There certainly is a westward trend with the potential TC and an even further westerly solution is indicated by the NMM. Weakly forced systems are difficult to forecast and so those uncertainties remain. Still, at this point, there aren't any solid indications that tropical moisture would be headed our way. As mentioned in the overnight discussion, the higher dewpoints expected later this week would tend to keep highs in check. All in all, Wed/Thu seem to be typical summertime values in terms of temp and dewpoint. Guidance has picked up on the potential for NW flow storms Wednesday evening though it's intrusion depth into our CWFA remains in question. Areas NW of a line from Denver City to Happy appear to have the best shot at seeing evening thunderstorms as they roll off the Raton Mesa. Some weak signals appear Thursday evening to our northwest, but indications are we'll remain largely dry. Friday continues to look to be our next shot at cool(er) weather as a more substantive trough axis passes across the northern plains. This will help drive a cold front into our region. Like last weekend, post-frontal cloudiness and light precip will be possible. The first aforementioned trough does seem a bit weak to drive things as far south as indicated in some of the guidance. Another deeper trough swings by to our north on Saturday night increasing northwesterly flow through the latter extended and shunting the southwestern high into western Sonora or Baja California Norte. The ECM is really the only solution indicating the presence of a second surface frontal surge. Into early next week, the GFS seems substantially overzealous with pops along a NW/SE oriented frontal boundary and so will trim POPs accordingly. This is primarily triggered by low level moisture values significantly above those of other guidance and, more importantly, higher than expected given the synoptic regime. && .LUB WATCHES/WARNINGS/ADVISORIES...
