The episode as NWS LUB wrote it up.
Several outflow boundary existed across the region on the afternoon of the 21st which initiated isolated thunderstorm development. Strong instability and DCAPE allowed one storm to produce a severe wind gust near Abernathy (Hale County). This storm went on to produce a 57 mph wind gust at Lubbock Preston Smith International Airport (Lubbock 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 21, 2:01 PM CST, 35 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 301 PM CDT Thu Jul 21 2022 .SHORT TERM... Early afternoon radar imagery shows ongoing showers over the eastern Rolling Plains and far southeastern Texas Panhandle. This activity has mainly been sustained by a MCV that has been nearly stationary just to the southeast of the area. This activity should continue to move east through this afternoon. Additionally, a few outflow boundaries have been noted on RADAR and the West Texas Mesonet. Surface heating and convergence along the aforementioned outflow boundaries, will bring the potential for airmass thunderstorms this afternoon. Storms that form will slowly drift south within weak flow, and in an environment consisting of MUCAPE values of 1000-1500 J/kg, PWAT values of 1.3"-1.6", and DCAPE values ~1000 J/kg. In this environment, storms that form will be capable of downburst winds up to 65 mph, localized heavy rain, and small hail. Any storms that form, should start to decrease in intensity and coverage with the loss of surface heating. Additional storms will move towards our area this evening and may enter the forecast area late tonight. Currently this seems less likely than previous nights, as some drier air aloft is advected into areas of northern New Mexico and southeastern Colorado. Tomorrow will be a little hotter, as the upper high will move a bit east, resulting in increased thicknesses. Isolated airmass thunderstorms will be possible once again tomorrow afternoon, as monsoonal moisture will remain over the area and hot conditions will remain. GKendrick .LONG TERM... Long term forecast remains on track this afternoon with an expected pattern change mid to late next week. This weekend though upper- level ridging will remain in place across much of the southern CONUS. This will keep temperatures on the warm side with afternoon high temperatures mainly in the upper 90s to lower 100s with morning low temperatures mainly in the 70s. With increased subsidence and decreasing mid-level moisture over the forecast area during the weekend the area should dry out with mostly sunny conditions. By mid to late next week there still appears to be a slight pattern change as large scale troughing encompasses the central U.S.. This will send a cold front down into the Southern Plains however it remains unclear at this time how strong the front will be. What has increased in confidence is the return of better precipitation chances to the region as both the GEFS and ECMWF have PoP values as high as 70%-80% across the southern Texas Panhandle late next week. While precipitation is not expected to be heavy at this time any precipitation will be welcomed. /WCI && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 10/58
