The episode as NWS LUB wrote it up.
On the afternoon of the second, thunderstorms initiated along an old outflow boundary in the Rolling Plains. These storms were aided by some lift from a weak upper level jet streak moving across southwestern Oklahoma. These thunderstorms propagated to the southeast through the late afternoon hours. A very deeply mixed atmosphere contributed to these thunderstorms producing severe wind gusts. The strongest storm of the day produced a wind gust to 98 mph near White River Lake (Crosby 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 Aug 2, 1:08 PM CST, 3 hours 42 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 208 PM CDT Sun Aug 2 2020 .SHORT TERM... Upper level flow has become more northwesterly today and in turn, the weather is expected to become more active into the evening and overnight hours. Speed max is making its way across SWRN OK with the CWFA increasingly under the influence of the favorable right entrance region. As mentioned in the morning update, thermal profiles show some instability and potential for a few storms to fire this afternoon. There are a couple of boundaries that have potential to initiate convection. The first is along a line from Roaring Springs up to Wayside. A second boundary was oriented near the US385 corridor. Thus far, some weak echoes were noted in Lamb County though these failed to become established. Still, there are several hours of heating. Convection is starting to fire from the Raton Mesa to the eastern slopes of the Sangre de Cristo range. This activity is expected to congeal into an MCS as the afternoon progress and potentially reach our NWRN zones by around 00Z. This complex should move across the better part of the CWFA overnight with a threat of downburst winds to 65 mph and perhaps some dime to nickel size hail particularly before midnight. Thereafter, we should see more of a transition to a rain event with beneficial rainfall for a fairly wide swath. Rainfall amounts will range from a trace to a couple of inches with a median perhaps in the 1/4" to 1/2" range give or take. Subsidence increases on Monday leading to drier conditions and highs close to seasonal norms. .LONG TERM... The upper high will be centered over ern AZ/wrn NM by late Monday with the upper ridge extending nwd along the spine of the Rockies. An impulse passing through the ridge is expected to spawn scattered tstms along the higher terrain of Colo and nrn NM Monday afternoon. NW flow aloft will carry this activity toward our forecast area Monday night. Low-lvl instability will be seomwhat lacking due to cooler, drier easterly flow at the surface, but some positive theta-e advection around 850mb is progged to accompany a modest LLJ, and will possibly be sufficient for some of the convection to reach the western South Plains overnight, although the coverage and strength of the activity should be waning. Tuesday, the upper high begins to migrate eastward, bringing rising heights and temperatures across West Texas. Another shortwave is forecast to break through the upper ridge late Tuesday, producing another round of late evening and nocturnal convection, although the best precip chances should shift northeastward into the Panhandles due to the building srn portion of the ridge. The upper high center continues to slowly move east across south Texas Wednesday into Friday, while becoming increasingly elongated E-W as a deeper trough develops across the western CONUS. This pattern with W-SW upper-level winds across west Texas should drag the SW monsoonal moisture plume northeastward into the southern High Plains. While the focus for this moisture will be across nrn NM into the Panhandles, it looks like enough moisture could seep south and east through the northwest flank of the ridge to support rain chances at least for our northwest and northern locations. The subtropical moisture plume thins as we head toward the weekend, but may not disappear completely, with our western counties having at least a shot of evening or overnight convection as weak westerly flow carries NM diurnal activity eastward. && .LUB WATCHES/WARNINGS/ADVISORIES...
