Quarter to half dollar size hail in Canyon.
Hail in Texas, June 24, 2017
In the wake of the passing cold front, low level residual 850-700 hPa moisture boundary was set up over the northern Texas Panhandle. With a mid-level trough working SE out of Colorado along with MUCAPE up near 1500 J/Kg, there was enough mid level instability to generate a cluster of storms considering all these reports occurred overnight.

What happened
The episode as NWS AMA wrote it up.
In the wake of the passing cold front, low level residual 850-700 hPa moisture boundary was set up over the northern Texas Panhandle. With a mid-level trough working SE out of Colorado along with MUCAPE up near 1500 J/Kg, there was enough mid level instability to generate a cluster of storms considering all these reports occurred overnight. These storms moved south along boundaries generated by the line of clustered discrete cells producing several hail reports.

Area forecast discussion, Jun 23, 11:56 PM CST, 47 minutes before
Area Forecast Discussion...UPDATED National Weather Service Amarillo TX 1256 AM CDT Sat Jun 24 2017 .AVIATION... For the 06Z TAFs, showers and tstms developing across mainly southern Texas Panhandle may affect KAMA during the first few hours of this cycle. Will monitor radar trends closely early this morning. Otherwise, the next round of showers and tstms will be possible late this afternoon and evening, and have incorporated PROB30 groups at KDHT and KAMA as these locations have the best chance of being affected, with KGUY possibly being impacted just beyond this fcst period. Andrade && .PREV DISCUSSION... /Issued 616 PM CDT Fri Jun 23 2017/ AVIATION... VFR conditions to start off the 00Z TAF cycle. Forecast confidence will be low due to the possibility of convection at the terminals after 10Z through the end of this forecast cycle. Have inserted PROB30 groups to KAMA and KDHT to cover possibility of convection impacting the terminals. General thinking is that convection will initially start across the far southern and western Panhandles tomorrow morning before spreading across the Panhandles throughout the day. There is a possibility of convection affecting KAMA during the early morning hours but confidence was too low to mention in prevailing. KGUY may not be affect by convection until after 00Z Sunday. Should convection impact the terminals directly then low ceiling/visibility and gusty variable winds. Outside of convection, winds will generally become light and variable after 03Z through the overnight hours. Winds will become southerly and increase to 12kt to 15kt around 18Z Saturday. PREV DISCUSSION... /Issued 454 PM CDT Fri Jun 23 2017/ DISCUSSION... Negative tilted upper level high pressure system to the west will continue to work east and become more north/south oriented by Monday night as it sets up over the four corners region. Large scale surface high will continue to move southeast across the central CONUS over the weekend. By Sunday evening it looks to be centered over the Missouri area, and warm moist low level air will return to the entire Panhandles. The southwest area could see some good moisture return as early as Saturday night, with smaller surface high expected to cross the northeast Panhandles Saturday morning. Otherwise, most of the low level moisture will remain south of the Panhandles, giving most of our chances for showers/storms across the western and southern TX Panhandle. In addition to keeping low level moisture to the south, the cooler air from the north will keep the area below normal for daytime highs on Saturday and possibly Sunday. Right now highs on Saturday look to be in the low to mid 70s, with maybe a few areas to the northeast in the mid to upper 70s. It's possible the a new record lowest high temperature could occur at one of our climate sites, as some guidance is suggesting that some areas could struggle to reach 70. Have not gone this aggressively cool as it's an outlier to the mean. Also, today's highs have come in a little warmer than expected as well. This occurring, even with the breezy north winds today, leads me to have lower confidence that it will be that cool tomorrow. Saturday, the area will still be under northwest flow and there is still enough moisture at the 700H level that showers and storms could develop to the west and track southeast into the Panhandles. Hence the chance POPS to the west and slight chance POPS to the east. Saturday night moisture will start to slowly work its way into the southwest Panhandles. At this point POPS have been increased into the likely category and moderate rain with some of the storms has been noted. PWAT values Saturday night range 1.3 - 1.5 inches over the southwestern Panhandles supporting the potential for moderate rain. In addition, 0-6km shear in the 20-30kt range supports some slower moving storms. As the surface flow shifts more southerly on Sunday temperatures will begin to warm, but highs may still struggle to reach 80. The potential for moderate rain, especially over the west will continue through Monday evening. By Tuesday high pressure over the four corners region will begin to be suppressed by an upper level trough moving down from British Columbia. This will provide a more zonal flow to the area. Warmer and drier conditions are expected, but have still kept a slight chance of POPS through Tuesday night. 850H temps on Wednesday and Thursday could return back into the +30C range, leading to widespread 90s to possible low 100's again for the Panhandles. Dryline looks to possibly set up east of Amarillo leading to strong inverted V soundings up to 550H. Model soundings indicated possibly uncapped but very low CAPE values above the LCL. East of the dryline where the temperatures will still be very warm/hot, models hint at a 700H capped warm nose, inhibiting convection. However, with the upper level trough axis moving over the Rockies on Thursday models do hint at some forcing that could overcome the cap and therefore have noted a slight chance of storms to the east on Thursday.
