The episode as NWS LUB wrote it up.
Early evening thunderstorms developed over the southern Rolling Plains south of a stalled cold front. Some of these storms became severe over Stonewall County producing golf ball size hail. Late in the evening and behind the front, a compact supercell thunderstorm developed in far southwest Lubbock County and affected areas from just south of Wolfforth (Lubbock County) east to the southern extent of Lubbock (Lubbock County).

NWS Lubbock, TX wrote its last area forecast discussion before the first event at May 19, 2:05 PM CST, 3 hours 50 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 305 PM CDT Fri May 19 2017 .DISCUSSION... Convection from this morning has muddied up the atmosphere a bit for convective chances for the remainder of the afternoon. However, it looks as though there may be a narrow area to see convection continue to develop through late afternoon. Clearing clouds have allowed temperatures to warm to values ranging from the lower to mid 80s over the southern Rolling Plains south of a stalled out cold front. This stalled out front has also allowed for weak convergence over the Rolling Plains. Ample low level moisture was still in place with surface dew points in the lower 60s. These temperatures have warmed enough to break the cap with mixed layer instability only on the order of 1000-1500 J/kg. Strong shear still present will continue to support a potential for severe storms. The stalled out cold front will make a stronger push through the region tonight. The upper low currently spinning over Colorado will move out onto the Plains on Saturday but cooler and drier surface air will filter in behind the front. A pseudo rex block will form off the west coast early next week setting up the next potential convective chances although we will mostly be in northwest flow aloft. An increase in jet level winds will occur on Monday as a short wave from the northwest skirts the area Monday night. Moisture recovery will be fairly weak ahead of this short wave from the northwest which may limit the amount of significant convection on the South Plains. Models are in good agreement in moving a front through the area during the day on Tuesday. This front will plow down well into the Gulf of Mexico which will keep low level moisture at bay for a while. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && 01
