The episode as NWS LUB wrote it up.
Warm temperatures, surface convergence along a dryline, and an unstable atmosphere contributed to scattered severe thunderstorms across the South Plains and western portions of the Rolling Plains late in the afternoon into the evening hours of the 17th. A very dry sub-cloud layer allowed one of these storms to produce wind damage in the city of Lubbock while also producing hail up to two inches in diameter. Thunderstorms dissipated off the Caprock but produced a couple of heat bursts while dissipating. The first heat burst occurred near Hackberry producing a wind gust of 60 mph. The second occurred near Aspermont with a Texas Tech University West Texas mesonet site measuring a wind gust of 59 mph.

NWS Lubbock, TX wrote its last area forecast discussion before the first event at Jun 17, 5:35 PM CST, 3 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Lubbock TX Issued by National Weather Service Norman OK 635 PM CDT Tue Jun 17 2025 ...New AVIATION... .KEY MESSAGES... Updated at 627 PM CDT Tue Jun 17 2025 - Triple-digit temperatures expected for much of the region through this evening, and a Heat Advisory is in effect for much of the South Plains through 9 PM. - There is a low chance of thunderstorms mainly off the Caprock this evening and again Wednesday afternoon, some storms may be strong or severe. - Dry and unseasonably hot conditions are expected Thursday through the weekend before low storm chances return next week. && .SHORT TERM... (This evening through Wednesday) Issued at 237 PM CDT Tue Jun 17 2025 Upper air analysis early this afternoon depicts broadly cyclonic flow aloft in place over most of the CONUS, with flat upper ridging centered over NW Mexico and Baja CA. A quick-moving upper shortwave trough was passing over CO at 18z, with this feature expected to continue moving eastward over KS and into MO this evening. At the surface, a dryline continues to sharpen near the I-27 corridor with broad surface troughing continuing to deepen over eastern NM. The dryline will continue to mix east through the rest of the afternoon and will position near the edge of the Caprock by this evening. Robust thunderstorm development associated with the aforementioned upper shortwave trough is still expected to remain well to our northeast this evening in closer proximity to the stronger large scale forcing. However, weak low level confluence associated with the surface trough and dryline circulation could also result in a few isolated storms essentially anywhere east of I-27 this evening. Current thinking is that any storms will remain fairly short-lived and quite sparse in coverage across our area given the relatively dry and well-mixed boundary layer and the displacement of the large scale forcing to our northeast. Still, if a stronger or longer-lived cell can establish, the relatively dry sub-cloud layer and forecast deep inverted-v sounding structures point to a potential for an instance or two of a strong or severe wind gust, especially over the SE TX Panhandle and the Rolling Plains. Dry conditions are expected area-wide tonight. A cold front will slowly move southward through the overnight hours, with the associated shift to northeasterly surface flow arriving to the entire forecast area by sunrise on Wednesday. Temperatures on Wednesday behind the front will be cooler than today, but the cooldown will be subtle given the influence of expanding upper ridging to our west. Most areas are expected to see highs in the upper 80s to mid 90s, still near or above average for this time of year. Surface flow will remain predominantly northeasterly to easterly throughout the day, with a surface trough extending from the Permian Basin up into the Rolling Plains keeping at least some areas off the Caprock within southerly surface flow. The majority of the forecast area is expected to remain dry on Wednesday, though there is a slight chance of evening thunderstorms across the southern Rolling Plains within the zone of weak confluence associated with the aforementioned surface trough. Plentiful instability may support a strong or severe storm or two in this area, but a displacement of the strongest forcing to our east is once again expected to keep the severe threat relatively limited across our forecast area on Wednesday. && .LONG TERM... (Wednesday night through next Monday) Issued at 237 PM CDT Tue Jun 17 2025 Dry and unseasonably hot weather is expected across West Texas from Thursday through the upcoming weekend as upper level ridging initially over the desert southwest builds northeastward. Friday and Saturday are currently expected to be the hottest days of the extended forecast period as the ridge axis centers overhead, with highs in the mid 90s to near 100 each day under clear skies. Sunday into early next week, the upper ridge will shift to our east and center over the OH Valley as broad upper troughing deepens over the western half of the CONUS. This will result in a slight cooldown as highs return to values near average, and will also bring a period of southerly to southwesterly flow aloft over West Texas which is progged to persist from Sunday into next week. Medium range models are in fairly good agreement depicting a mid/upper level moisture plume within the southwest flow aloft which will result in a gradual increase in storm chances primarily on the Caprock beginning on Sunday and continuing into next week. && .AVIATION... (00Z TAFS) Issued at 627 PM CDT Tue Jun 17 2025 Scattered thunderstorms are possible at all sites for the next couple of hours. Gusty and erratic winds and reduced visibility are possible with any storms. Otherwise, breezy southerly winds will become northeasterly, then easterly by this afternoon. Gusts of 20-25 kts are possible at KPVW and KLBB. VFR will continue. && .LUB WATCHES/WARNINGS/ADVISORIES... Heat Advisory until 9 PM CDT this evening for TXZ027-028-033>035- 039>041. && SHORT TERM...30 LONG TERM....30 AVIATION...19
