During the late afternoon to early evening of the 29th a line of storms formed along a stationary boundary running along the southern bank of the Canadian River Valley in the Texas Panhandle. One supercell was able to form off of this line and first produced an estimated 80-85 mph wind gusts in Carson County as it knocked over nine power poles along HEY207.

The episode as NWS AMA wrote it up.
During the late afternoon to early evening of the 29th a line of storms formed along a stationary boundary running along the southern bank of the Canadian River Valley in the Texas Panhandle. One supercell was able to form off of this line and first produced an estimated 80-85 mph wind gusts in Carson County as it knocked over nine power poles along HEY207. As this supercell matured it moved north into Hutchinson County where it caused more wind damage but also hail up to 1.5 in diameter.
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 Amarillo, TX wrote its last area forecast discussion before the first event at Jun 29, 2:48 PM CST, 2 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service Amarillo TX 348 PM CDT Sat Jun 29 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Sunday night) Issued at 225 PM CDT Sat Jun 29 2024 Cold front has made its way to near Highway 60 and is finally showing signs of stalling as expected. CU has begun to form near and behind the boundary with even some moderate CU noted. The dewpoints behind the front remain in the 60s, but some 40s dewpoints have pushed across the northern half of Kansas with a subtle second surge. Thunderstorms are expected to develop first near the boundary with Amarillo on the southern edge of the activity this aftn. A second area of development associated with a mid-upr level S/WV and elevated portions of the front is expected later this evening moving out of NM into the NW Panhandles. Severe parameters all favor areas further north behind the front and this activity has the greater chance for becoming more organized and widespread. ML CAPE across the north is forecast to 1500-2500 j/kg and effective bulk shear is forecast to remain 40-50 kts. Warmer mid level temps seem to favor wind over hail for the greatest threat. High moisture content and a modest h85 LLJ reaching 25-30 kts will also aid in providing threats for heavy rainfall and flooding. HREF probs indicate up to 40-60% probs of 1 hour rainfall rates of 1 inch or greater and storm total probs exceeding 3 inches are around 10-20% across the north. We strongly considered a flood watch across the north-northwest, but held off as there are some concerns that several cams have recently backed off convection in the northwest. This seems to be tied to models that are more agressive with the dry air moving into the area from the north which leads to greater capping and much less convection. If it becomes more apparently things are coming together (18Z models back to favoring this), we may need to consider a short lead flash flood watch. SPC continues to maintain a slight risk for the NW and WPC is maintaining a slight risk for flooding in similar region. Some lingering showers will be possible tomorrow. There are CAMS attempting to convect weakly along the stalled boundary mainly across the east given very moist conditions, but w/ H5 negative vorticity building overhead and ridging extends over the area from the SE and H5 temps warming to an impressively warm -2 deg C. This suggest any activity would almost certainly not be severe and may not exceed shower status. After lingering chc pops (30-40%) across the NE in the morning, aftn POPs are being held at 10-20%. && .LONG TERM... (Monday through next Friday) Issued at 225 PM CDT Sat Jun 29 2024 The H5 high building over the area Sun into Mon will lead to hot temps on Monday and Tuesday. PDC will likely exceed heat advisory criteria both days and a few other typical hot spots in the area may also approach advisory levels as well. The high will transition east allowing H5 heights and temps to fall. S/WVs in SW flow followed by NW flow aloft, high moisture levels and another frontal boundary (eventually) will lead to potential for daily convection Tue night through Sat night. Obviously details are sketchy at this point, but certainly it appears an active period could impact holiday activities. && .AVIATION... (18Z TAFS) Issued at 101 PM CDT Sat Jun 29 2024 Two concerns for this TAF cycle include thunderstorms in the area and late night and morning low CIGS. Abundant moisture will interact with a soon to be stalling frontal boundary and upper level disturbance to produce at least SCT TSTMS by late aftn or early evening. Initial storms will be near the boundary near or just north of Amarillo, with better chances spreading behind the front into the northern Panhandles in the evening and overnight hours. All sites have potential for impacts, but DHT and GUY have greatest chances and some storms in the area will have potential to produce SVR level winds and localized flooding. Low CIGs near IFR ranges are expected to spread into the area behind the front in NE flow across the northeast Panhandles and GUY has high enough probability for IFR CIGs that this has been included in the TAF Sun morning. Some MVFR visibility is also expected again mainly near GUY and adjacent areas to the E/NE. && .PRELIMINARY POINT TEMPS/POPS...
