Despite a lack of large scale lift on the afternoon of the ninth, enhanced low level convergence along the caprock escarpment allowed for isolated thunderstorms to develop around Briscoe County. Ample instability in place allowed one of these storms to become severe producing large hail northwest of Silverton (Briscoe 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 9, 1:27 PM CST, 2 hours 40 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 227 PM CDT Fri Jun 9 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Saturday) Issued at 223 PM CDT Fri Jun 9 2023 Focus this afternoon is on near-term convective chances. CAMs this afternoon are far from being in agreement on convective potential this afternoon to early evening. What consensus there is is for isolated showers/thunder along modest convergence in the vicinity of the Caprock escarpment, perhaps with an orographic component, with strongest signal in the lower end of Palo Duro Canyon. The inherited narrow band of 15-20 percent PoPs look fine for the 21Z-03Z time frame. Afterwards, will be looking at the potential for the two better areas of late day to early evening thunderstorm chances, i.e., the northern Panhandle and southwest Texas, to build toward, and maybe into, the forecast area either through discrete motion in the case of the southwest Texas convection or building along outflow boundaries southward through the eastern Panhandle. The latter at this time seems the most likely as it also lines up better with potential upper support from an upper level short wave trough progged to across southeastern New Mexico to the western Panhandle later tonight. Will give a slight increase to the magnitude of precip chances late tonight in the northeastern zones as a result. Saturday is expected to be precip-free as surface and low level flow back to the southwest in the wake of the departing upper level trough, which in turn shifts any low level convergence and convective focus to the east of the forecast area. Temperatures tomorrow look pretty similar to today, holding just above the climatological mean. && .LONG TERM... (Saturday night through next Thursday) Issued at 223 PM CDT Fri Jun 9 2023 Little change from the previous forecast through the extended. A weak back door surface cold front will stall over our area Sunday afternoon as an upper level ridge axis slowly pivots east. The stalled surface front will begin to move farther south and southwest after sunset on Sunday, potentially with some assistance from outflow associated with an MCS in the northern Texas Panhandle. Increasing clouds behind the front/outflow overnight Sunday into early Monday will be the net result. Temperatures Sunday and Monday will be below or at seasonal averages for most locations before starting to climb above normal for the middle and end of next week. Slight chance PoPs for Monday afternoon and evening behind the front seem reasonable, though the coverage may be too far west. The southern half of the Rolling Plains seems most likely to see storms where daytime heating will be sufficient, along with dewpoints in the low to mid 60s. The Omega Blocking pattern will begin to break down during the day Monday, with primarily zonal flow across our region at least Tuesday and Wednesday. Deterministic guidance begins to diverge somewhat beginning Wednesday night wrt the longwave synoptic pattern. The ECMWF maintains the mostly zonal pattern through the remainder of the week into next weekend, while the GFS firmly establishes northwest upper flow across our area. Implications for our high temperatures, especially next Thursday and Friday, could be significant, with the NBM currently leaning heavily toward the ECMWF and the zonal flow which is the warmer solution. Beyond that, into next weekend, there appears to be another potential Omega Block developing across most of CONUS. && .AVIATION... (18Z TAFS) Issued at 1210 PM CDT Fri Jun 9 2023 Isolated TS possible this afternoon/evening along a weak dryline as an upper level disturbance approaches from the southwest. Initiation, if it occurs, likely to be east of KPVW and KLBB and with a chance of affecting KCDS. Confidence, however, is very low and will leave mention out this TAF cycle. Otherwise, VFR conditions are expected to continue. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...07 LONG TERM....55 AVIATION...07
