The episode as NWS LUB wrote it up.
Another day of record heat allowed isolated thunderstorms to develop late in the afternoon of the 14th. One of these storms produced a severe wind gust to 67 mph near Floydada (Floyd 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 Jul 14, 5:42 PM CST, 1 hour 48 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 642 PM CDT Tue Jul 14 2020 .AVIATION... It is scorching hot this evening (check density altitude), and this heat has caused isolated very high-based pinpoint convection to develop. Any rainfall will be spotty and light, but lightning and gusty/erratic outflow winds could impact any/all of the terminals this evening. Hence, we have carried VCTS in the TAFs the first several hours of the forecast and will amend if a more direct/significant terminal impact becomes more likely. Otherwise, VFR will prevail. A weak front will sag in from the north on Wednesday bringing a northerly/northeasterly wind shift to the northern terminals (and perhaps KLBB) before stalling out. Any sub-VFR cigs should lag well behind the front, north of the terminals, but the developing upslope flow and increased moisture may provide a better chance of showers and thunderstorms Wednesday evening. && .PREV DISCUSSION... /issued 246 PM CDT Tue Jul 14 2020/ SHORT TERM... The last day of record to near record heat is upon us today as overall thicknesses begin to decrease for tomorrow. Latest model guidance continues to be all over the board with where evening thunderstorm development will occur. The best chance at seeing thunderstorms will remain across NM and the northern Panhandle however isolated showers and thunderstorms will be possible across our area as well similar to what occurred yesterday. Guidance has been consistent regarding the timing of the activity which is set to develop after 5pm CDT this evening and persist into early tomorrow morning. Any activity that does develop will be capable of producing gusty downburst winds to 65 mph. Around daybreak a weak front will drop into the northern parts of the forecast area which will bring northerly winds and slightly cooler temperatures to the area depending on how far south it makes it. Similar to last night, it appears that mid to high cloud cover may stick around through the night which will help to keep overnight temperatures well above normal once again where this does occur. As stated previously tomorrow thicknesses will be a bit lower compared to today so while temperatures will remain hot they will be 100-105 degrees instead of what we are experiencing today. The southern portion of the Caprock will remain near 105 degrees so a small heat advisory may be necessary through tomorrow evening. Even though the air temperature will be cooler low level moisture will also increase behind the dropping front, so it won't feel all that much nicer. To prevent the mixing of messages will hold off on issuing any heat products for tomorrow at this time. Isolated thunderstorms will be possible once again tomorrow afternoon along a surface trough near the NM/TX state line and the cold front that will be dropping south across the area. As has been the case this activity will be capable of producing gusty downburst winds. /WCI LONG TERM... The southern half of the CONUS looks to remain primarily under the influence of upper level high pressure for the next week. However, the good bit is that the core of the upper level high will shift eastward on Wednesday offering cooler temperatures. Unfortunately, when I say cooler, I mean closer to 100F. The flips side is that the dewpoints will rise thanks to the influence of monsoon moisture. As such, it should not feel that much cooler from an apparent temperature perspective. After some weakening of the ridge into early next week, indications are the ridge will strengthen once again to our NW (potentially centered on Colorado). The best shot at thunderstorms Thursday afternoon and evening looks to be up across the panhandle though we could see a few storms out near the TX/NM state line in our western zones. Friday looks drier region-wide as does the remainder of the extended. To help cooling, keep the curtains closed, and clean those air conditioner coils with a gentle stream of water so as to help with heat transfer. && .LUB WATCHES/WARNINGS/ADVISORIES... Heat Advisory until 9 PM CDT this evening for TXZ021>026-031-032- 037-038-043-044. Excessive Heat Warning until 9 PM CDT this evening for TXZ027>030-033>036-039>042. && 58/26/23
