The episode as NWS LUB wrote it up.
Isolated thunderstorms erupted this afternoon along a southward moving cold front. The southeast movement to these storms allowed some to parallel the front and acquire supercell structures that created swaths of large to very large hail. An EFU tornado accompanied one of these supercells in Stonewall County and was photographed by many storm chasers.
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 Lubbock, TX wrote its last area forecast discussion before the first event at Apr 27, 2:23 PM CST, 1 hour 42 minutes earlier.
Area Forecast Discussion National Weather Service Lubbock TX 323 PM CDT Sat Apr 27 2019 .DISCUSSION... Let's first cover what's going to happen this afternoon and tonight. A cold front has been slowly sagging southward this afternoon out of the TX Panhandle into our FA, and as of this writing was draped from northern Oldham county to somewhere diffusely around Collingsworth County. On the flip side, a dry line was crossing the TX/NM border through Bailey down to Yoakum counties and moving eastward. Around 1500J/kg+ CAPE had built up from Castro down through Hale to Lynn counties and eastward with CIN rapidly decaying. Therefore, the first storms were going up ahead of the frontal boundary along the dryline in Parmer County. Whew...and that's just the setup! Ok, what's going to happen now? Storms are expected to continue to fire along the meeting point of the front and dryline over the next several hours and head eastward. Low-level shear is quite lacking, but the deep shear is healthy at 40-50 KT, good enough for supercells. Inverted-V sounding profiles lead to the thought of damaging downburst winds, but we must also think about the potential for hail...big hail. Lapse rates sfc to 3km are on the order of 9-10 deg C/km and going up, 3-6km still a healthy 8 deg C/km. Hail around 1-2" with most storms should suffice, but it would not surprise if a few of the stronger cells produce over 2" hail. While all this is going on, a low will be moving south out of Alberta, pulling a cold front behind it this evening. Flow later tonight will turn just slightly NW. The dryline will retreat overnight, allowing for areas of patchy fog across portions of the southern South Plains. During the day tomorrow, somewhat zonal flow returns, and there's a marginal chance the dryline could become active in the afternoon. This is highly conditional, so went with silent PoPs for the time being. A low off SOCAL will be developing and deepening and that aforementioned Canadian low will be skimming the border of the US in ND, still sending its front southward. Aloft, we'll see southwest flow return, which will start to play into our weather picture on Monday. So, let's head into Monday. That SW flow will start pulling in a chunk of Pacific moisture ahead of the SOCAL low, just making it onshore. By this point the Canadian low will have washed out, but the ensuing front will still be moving south, now knocking on the door of the TX/OK Panhandles. By Monday afternoon, that front is expected to stall out across part of our FA with the SOCAL low now moving into the Desert SW (oh, and that moisture is still getting pulled in!). Monday night is when things change again. Storms are expected to break out along the stalled front...heard this story before? Again, we will have to see exactly how far south the front goes to know exactly where storms break out, but they are expected to lift north across the boundary. There is a slight chance some of these could be severe. While this event is ongoing, our low will be lifting into the Four Corners and beginning to open into a trough. By Tuesday morning, the opened trough will lift far enough northeast to provide extra lift across our area to continue the overnight convection through around midday; however, as it continues to weaken and lift north, we loose the extra energy and rain exits to the east by the afternoon. Wednesday appears to be our inbetween day with things pretty calm before the next system hits. Early Thursday morning, a southern ripple in the flow creates storms south of the region and moving north aided by the pull of northern trough over N Central Plains. All the while, a front will be working in making this round rather short by pushing the convection out by midday. This will be a short- lived lull. Gulf moisture slipping around the backside of a ridge on Friday starts storms in the high terrain of NM and possibly a bit in our area. Another low off the coast of Cali deepens as it moves onshore late that evening as we return to NW flow. Finally, continued Gulf moisture rips across the high terrain of NM on Saturday, mixing with W/NW flow and may push storms our way. What a week of weather. && .LUB WATCHES/WARNINGS/ADVISORIES...

While most storms will produce hail of around 1-2" in diameter, the most severe storms will be capable of producing hail up to 2.5" in diameter. Damaging wind gusts to 65 mph and locally heavy rainfall are also possible. .DAYS TWO THROUGH SEVEN...Sunday through Friday No hazardous weather is expected at this time. .SPOTTER INFORMATION STATEMENT... Spotter activation is requested.
The Lubbock radar (KLBB), 58 km away, was scanning. The volume nearest the first event began at 22:05 UTC.
4 hail, 1 thunderstorm wind, 1 tornado. Local standard time, as filed.
A swath of severe hail up to 1.5 inches in diameter fell in and near Floydada. Damage information was not available.
Severe hail up to half dollar size was reported, but damage information was not available.
Measured by a Texas Tech University West Texas mesonet.
Damage information was not available.
Multiple storm chasers documented a tornado drifting southeast near Peacock. This tornado did not cause any known damage as it remained over open land.
A tornadic supercell produced a long swath of severe hail ranging in size from quarters to as large as baseballs at times. Damage photos from social media indicated some cars sustained heavy damage, but damage to homes or other property was not known.
