The episode as NWS MAF wrote it up.
An upper level trough was centered over southern Canada and extended southward into Texas. A dryline developed across West Texas during the afternoon with very moist air to the east of this feature. Wind shear was fairly high across the area, and there was high instability. Thunderstorms to the north of the area during the morning left a boundary in place which became a focus for thunderstorm development during the afternoon and evening hours across the Permian Basin. These conditions contributed to thunderstorms that developed across the Permian Basin and in Brewster County that produced large hail and strong winds.

Area Forecast Discussion National Weather Service Midland/Odessa TX 228 PM CDT Sat Jun 20 2020 .DISCUSSION... An upper level trough is centered over southern Canada and extends southward into Texas. A dryline is expected to develop across West Texas this afternoon with very moist air to the east of this feature. The NAM12 is showing CAPE (Convective Available Potential Energy) values of 2,000 to 4,000+ across West Texas and across portions of Lea County in New Mexico. Bulk wind shear values will get up to 30 to 40 knots across portions of the area. It appears that the convection to the north of the area this morning left a boundary in place that could be the focus for thunderstorms developing this afternoon across the Permian Basin. Thunderstorms are also expected to develop in/near the Davis Mountains and Lower Trans Pecos. These storms have the potential to become severe given the previously mentioned conditions. Temperatures today will be similar to those yesterday with highs in the 90s and triple digits. The upper trough axis will move east of the area on Sunday, and the dryline will be pushed to the far eastern Permian Basin and Lower Trans Pecos. Storms will continue to be possible across those areas, and the threat for severe storms will still be present. Temperatures on Sunday will heat up from today as westerly winds across much of the area contribute to downslope warming. Similar conditions will be present for Monday with temperatures heating up into the triple digits across most of West Texas and southeast New Mexico. It looks like Heat Advisories will likely be issued for Monday for portions of the area. A cold front is expected to move into the area Tuesday morning resulting in highs in the 90s for most of the County Warning Area (CWA). Rain and storms will be possible along this front. Rain and storm chances will increase on Wednesday from the previous day and temperatures will be a little cooler. Precipitation chances continue into Thursday with temperatures warming up a little from Wednesday. Temperatures will warm up and precipitation chances will diminish Friday and next Saturday. && .PRELIMINARY POINT TEMPS/POPS...
