Thunderstorms increased in coverage and intensity during the evening hours as more organized activity moved east out of New Mexico and developed into a broken line from I-40 near Endee, NM northeast to around Texline, OK. The northern portion of the line encountered a more favorable environment for strong to severe storms with potential for rotation from near Palo Duro Reservoir to Perryton.

The episode as NWS AMA wrote it up.
Thunderstorms increased in coverage and intensity during the evening hours as more organized activity moved east out of New Mexico and developed into a broken line from I-40 near Endee, NM northeast to around Texline, OK. The northern portion of the line encountered a more favorable environment for strong to severe storms with potential for rotation from near Palo Duro Reservoir to Perryton. Large hail was reported north of Perryton up to the size of ping pong balls which combined with strong winds took out some windows on a farmhouse along with other damage around the property. As this storm moved northeast it created winds estimated 85-90 mph since it took out several power distribution poles from Balko to Elmwood, OK leaving much of Beaver County without power. This storm quickly weakened not long after causing the power loss.

Area Forecast Discussion National Weather Service Amarillo TX 628 PM CDT Thu Jun 24 2021 .AVIATION...00Z TAFs... Potential for thunderstorms is the primary concern over the next 24 hours at all sites. A few thunderstorms are ongoing in the southwestern Texas Panhandle as of issuance time, but thunderstorm coverage and persistence so far has been uninspiring, so have covered the potential with VCSH mentions at all sites. Some wind shifts may occur as the showers approach, so this will be watched closely. Should a wind shift and/or thunderstorms appear likely to hold together toward a TAF site, amendments will be issued. Looking ahead to Friday, another round of showers and thunderstorms looks to be possible by the late afternoon. As usual, exact timing and placement remains uncertain. With three TAF cycles to go, have also used VCSH late in the period, with additional refinements in timing and explicit mentions of thunder to be added as confidence increases. Otherwise, wind direction is highly uncertain at GUY as a front will approach from the north and may stall and/or retrograde Friday afternoon. Ferguson && .PREV DISCUSSION... /Issued 250 PM CDT Thu Jun 24 2021/ SHORT TERM...Tonight through Tomorrow Night... Synopsis: Isolated to scattered thunderstorms are expected through this evening for all but the far eastern TX Panhandle. A few of these storms could produce damaging winds, small hail, and heavy rain. Another round of storms is expected tomorrow afternoon into the evening hours, with greater coverage. Some storms tomorrow will also be capable of large hail near golf ball size and damaging winds. A landspout is also possible tomorrow near surface boundaries. Current analysis: The latest upper level analysis places high pressure centered over North Texas with two upstream shortwave troughs, one near northern coast of CA and one moving into the Great Basin region. Between these two troughs are very subtle disturbances, including one that is embedded in the weak southwest flow aloft moving through portions of eastern NM and west TX. Virga and high based storms have already been occurring the western combined Panhandles this morning in response to mid and upper level ascent associated with embedded disturbance noted on WV imagery. At this feature advances east northeast this afternoon, it will interact with a diffuse dryline / sfc trough stretched from near Hereford to near Beaver. A boundary had also pushed through western and north central portions of the combined Panhandles with north winds and drier air in the wake, but this boundary is now starting to lift back to the north. Mesoscale forecast: The main area of focus for isolated to scattered storm development will be along the surface trough / diffuse dryline as the upper level disturbance traverses the boundary between 2 PM and 6 PM. This will occur in the presence of a well mixed boundary layer, where surface dew points in the low to mid 50s will be common with temperatures in the upper 90s. Convective temperatures today near the boundary are around 99 degrees (based on KAMA 12z sounding), so convective inhibition should be minimal by 4 PM given forecast temperatures near that value (AMA @ 96 as of 2 PM). A cap will be more prevalent in the eastern Texas Panhandle, so storms may struggle as they move off Caprock. Any storms that get going between 3PM and about 9PM and stay near to just east of the boundary will have the best chance of producing damaging winds, small hail, and heavy rain. DCAPE values are large today (~1500 J/kg) with steep lapse rates up to 500mb. MLCAPE value along the boundary may approach 1000 J/kg, with values being slightly higher to the east of the boundary (where capping also increases). Shear is minimal today with 20 to 25 knots effective shear being common due to persistent southwest winds near the surface and relatively weak winds up to 300 mb. Thus, storms will be of pulse nature with single cell to multicell structures as near updrafts form on storm cold pools. Additional storm activity may move into the western zones later this evening with another subtle embedded disturbance, and may continue to pose a low end wind risk, especially if storms can stay rooted at the surface. For tomorrow, a bit more notable shortwave crosses the area with better return flow ahead of the system. This will result in better overall low level moisture advection with impressive 700mb theta-E axis in the area. A diffuse dryline / sfc trough will form in the afternoon with low 60s dew points in the central and eastern Panhandles (exact position of boundary uncertain, but generally near Bootleg to Slapout is current thinking). MLCAPE values will reach into the 2500 to 3000 J/kg range by early to mid afternoon with weak capping along the boundary. In addition, shear will be on the increase with much better directional shear due to persistent backed winds ahead of the boundary, which should include all but perhaps the far western Panhandles. Thus, supercell structures will be possible in the afternoon and early evening with some upscale growth in the late evening as the main wave moves through the area. While mid level temperatures are not very cold, rotating updrafts within moderate MLCAPE environment could produce large hail up to golf ball size along with damaging winds possibly near 70 mph (DCAPE remains around 1000 to 1500 J/kg). The tornado risk is low due to high LCL values, but steep low level lapse rates and good 0-3km CAPE suggests landspouts would be possible, especially along any remnant outflow boundaries. PWAT values approaching 1.5 inches and storm motions being slower (15 to 25 mph) suggest a localized flooding threat. Ward LONG TERM (Saturday through Wednesday)... We have what appears to be an active forecast through the long term with showers and thunderstorms forecast daily. This could result in a lot of cloud cover and cooler temperatures through this period as well. High temperatures are not going to feel like late June with 70s/80s forecast through the extended. This will end up being about 10+ degrees below normal through the end of June. Our normal highs are around the lower 90s this time of year. We begin the period in the wake of a cold front as an upper level trough swings through central parts of the CONUS. Depending on how fast the front moves through (and convection the next couple days) we could have thunderstorms across the area Saturday/Saturday night. Forecast soundings/hodographs suggest an abundance of precipitable water with slow storm movement from pulse type multicells. With storm training possible this could lead to excessive rainfall amounts and localized flooding, especially urban and low lying areas favoring the south/southeastern parts of the Texas Panhandle. Sunday and beyond will have chances for showers and thunderstorms every day. Coverage and timing is uncertain at this time given the complexity over the next 3 days. In fact, a lot will hinge on what happens the next few days. Additionally, the upper level pattern diverges quite a bit from model to model, so confidence is generally low Monday and thereafter. Generally speaking, we could see troughing over central parts of the CONUS in the extended with little progression which may aid our chances for thunderstorms each day.
