Late April and early May 2019 brought rounds of severe thunderstorms to West Texas, complete with pockets of heavy rain. Persistent southwesterly flow aloft, passing upper level disturbances and plenty of moisture and instability east of the dryline provided the ingredients for the rounds of severe weather. The weather first became active in late April and the first day of May. A write up of the severe weather that impacted the region April 27th, 30th and May 1st can be FOUND HERE.

After a quiet day on May 2nd, strong and severe thunderstorms developed on the afternoon of May 3rd near the TX/NM state line. One storm dropped hail as large as golf balls in Lazbuddie Friday afternoon. This activity moved east and southeastward through the late afternoon, while additional strong and severe thunderstorms formed in the Rolling Plains during the evening. One of the evening storms generated golf ball size hail as it tracked by just to the west of Jayton.

The next day, Saturday, May 4th, brought another round of severe thunderstorms across the western South Plains. The most intense storm dropped tennis ball size hail in Needmore. The storms rotated strongly and did also generate two very brief tornadoes over open land in Bailey County.

The severe thunderstorm tracked southeastward just south of Highway 84 before quickly dying during the late evening. An additional cluster of severe thunderstorms brought quarter size hail north of Dimmitt and a 63 mph wind gust near Tulia late in the evening.

The next day, Sunday, May 5th, was particularly active. The most intense storm of the day started in Lubbock County, but then sank south-southeastward through Lynn County where it produced a couple of tornadoes. The first tornado caused EF-2 damage as it tracked by to the northeast of Tahoka. A detailed summary of this active Sunday can be READ HERE.

Monday, May 6th, was not nearly as active as the previous day, though it did still provide a few strong thunderstorms across the southwest Texas Panhandle and northwest South Plains during the afternoon and evening hours. The storms, seen above, did make for some interesting and picturesque skies.

Tuesday, May 7th, brought a noticeable uptick in severe weather as a potent upper level storm system approached from the Four Corners. The most severe storm of the day started northwest of Lubbock and tracked steadily northeastward from there. The storm produced a brief tornado north of Halfway, and more substantial tornadoes southwest and northeast of Tulia. Thankfully, the tornadoes occurred over open land and didn't cause any known significant damage.

Additional strong and severe storms did form across the central South Plains into the evening. This activity dropped large hail and generated several wall clouds, but no known tornadoes.

The below pictures show a couple of wall clouds. The left image shows the storm that was occasional tornadic as it tracked past Tulia. The right image was from a storm later in the evening that produced a well-developed wall cloud near Shallowater before the storm weakened as it moved northeast from there.

The severe storms on Tuesday also dumped torrential rain, especially across parts of Swisher County, where they lingered longer. The heavy rain flooded several roadways west of Tulia where several inches of rain likely fell. The below pictures show the aftermath from the flooding the previous day. Middle Tule Creek rose several feet for a period during and immediately after the heavy rain Tuesday afternoon and evening.

The below plot shows the approximate location of the tornadoes that formed early Tuesday evening. Although the tornadoes were rated EF-U since they didn't hit any damage indicators and thus were not able to be assigned an intensity, straight-line winds that were estimated as high as 80 mph west of Vigo Park did snapped several power poles.

The following day (Wednesday, May 8th) was relatively quiet, that is until late evening and overnight. Thunderstorms erupted along and behind a cold front sinking through the South Plains. Just enough instability was in place to fuel intense thunderstorms that generated several pockets of large hail.

The below imagery shows the approximate swaths of hail, as estimated by radar. Hail as large as golf balls was reported southwest of Lubbock, near Wolfforth, just after midnight, while many other locations reported quarter to ping pong ball size hail between 10 pm on the 8th and 1 am on the 9th.

 

Multi-radar multi-sensor maximum hail size estimates from late Wednesday evening/night (8 May 2019). The dark blue and green colors represent hail sized near and in excess of 1" in diameter.

Quieter weather finally settled into the region on Thursday, May 9th. However, much cooler air also filtered in, which then led to a cold rain the next day when a strong upper level system approached and lifted warm moist air over the cool air at ground level. Impressively, temperatures didn't make it out of the 40s for most location on Friday, May 10th, as the cloudy and rain conditions dominated. Officially, Lubbock's high was 47 degrees, which set a new daily record minimum high (the previous record was 54 degrees, set in 1954).

Over the course of this active stretch of weather from late April through mid-May, widespread rain fell over the South Plains region. Rain totals of 2 to 4+ inches were common. This rain did result in some generally minor flooding at times, but it also led to a rapid green up. 

 

Radar-estimated, bias-corrected 30-day rain total ending at 7 am on 19 May 2019.
