The episode as NWS SJT wrote it up.
A strong upper level disturbance interacted with a moist airmass, causing an isolated supercell thunderstorm to develop in Crockett County. Then a line of severe storms developed across West Central Texas and moved eastward. The supercell thunderstorm and the squall line produced a few reports of large hail.

Area Forecast Discussion National Weather Service San Angelo TX 1243 AM CDT Sat Apr 13 2019 .AVIATION... /06Z TAFS/ A potent upper level storm system will bring showers and thunderstorms to the terminals overnight into the early morning hours. A few storm may become severe, with large hail and damaging winds possible. Showers and storms will end across the terminals by late morning, then light rain is expected across the KABI terminal during the afternoonhours behind the upper low as it tracks northeast across the area. Also, a surface cold front will move south across the terminals during the morning hours, with gusty north to northwest winds developing. Expect MVFR ceilings across the terminals for much of the forecast period, except at KABI where ceilings will lowering to IFR after 12Z and continue into Saturday evening. && .PREV DISCUSSION... /issued 659 PM CDT Fri Apr 12 2019/ AVIATION... 00Z TAFS/ The shower and isolated thunderstorm activity across the northern Concho Valley and western Big Country this evening will generally stay west of KABI. Showers and thunderstorms are forecast to develop, mainly after midnight, across western portions of the region, then move east through the morning hours. A few of the thunderstorms may be severe with an attendant risk of large hail and damaging winds. Most of the activity will move east of the area by late morning. In addition, low cloud development is expected during the early morning hours, which will result in MVFR ceilings. During the day Saturday, a cold front will advance south across the remainder of West Central Texas, reaching I-10 around mid- afternoon. Gusth north to northwest winds will occur behind this cold front. An area of wrap around rain will overspread the Big Country in the afternoon. IFR conditions are expected at KABI, amd MVFR ceilings are possible as far south as KSJT. Cloud ceilings should remain above 3000 ft at our southern terminals. PREV DISCUSSION... /issued 230 PM CDT Fri Apr 12 2019/ SHORT TERM... (Tonight and Saturday) .Severe thunderstorms possible overnight... A potent upper level trough currently located across the Desert Southwest will approach West Central Texas tonight into Saturday morning. Ahead of this feature, a disturbance in the southwest flow aloft will track across the area this evening. This may result in isolated to scattered shower and thunderstorm development along and just behind a cold front that will be moving into the Big Country. A few strong to severe thunderstorms will be possible. The greater threat of severe weather will be between midnight and 8 AM as the better lift from the aforementioned upper level trough moves into the region. High resolution models are indicating showers and thunderstorms initiating to our west, across the Trans- Pecos/Permian Basin, with scattered to numerous showers and thunderstorms then tracking east across the area during the morning hours. Initially, supercells will be possible, then storms may congeal into a line or broken line of storms. MUCAPE values will increase to 1000-2000 J/KG along with steep lapse rates and 0-6 KM Bulk Shear values between 45 and 55 knots. This will lead to the possibility of strong to severe thunderstorms, with large hail and damaging winds being the main concerns. There remains the potential for a tornado, especially near the stalled front which is forecast to be across central portions of the forecast area. In addition, 0-1 KM Storm Relative Helicity values across much of the area will be in the 350-500 range. The line of showers and thunderstorms should exit our area to the east by late morning or early afternoon. Scattered showers and thunderstorms may linger into the afternoon hours, especially across the Big Country, as the upper level trough/low tracks across the region. Much cooler temperatures are expected behind the front on Saturday, with extensive cloud cover expected. Highs will range from the mid 40s to lower 50s across the Big Country to near 70 in our southeast counties. LONG TERM... (Saturday Night through Thursday) As the upper low moves off to the northeast Saturday night, wrap- around moisture and rainfall will be possible across the Big Country mainly during the evening hours. Most rainfall should end by midnight Saturday night. Clouds clearing from west to east will allow for enhanced radiational cooling. This, in addition to the colder air mass that moved in, will allow lows to fall into the upper 30s across much of the region Sunday morning. Dry, warming pattern expected Sunday through Tuesday, with weak ridging aloft and gradually increasing moisture in low level southerly flow from the Gulf. Highs Sunday expected to be in the upper 60s to low 70s, then low to mid 80s Monday and Tuesday. Another upper level trough will drop down through the Central Plains Tuesday night through Wednesday night, but precipitation chances look to stay just east of our forecast area where moisture will be higher. Highs Wednesday expected to be in the low to mid 80s again. A cold front is projected to move down from the north Wednesday night, bringing slightly cooler, drier conditions. Expect highs Thursday in the 70s. No precipitation expected with this front. && .PRELIMINARY POINT TEMPS/POPS...
