Late May 2019 brought more rounds of severe thunderstorms to West Texas, including giant hail, damaging winds, tornadoes and torrential rain. An active dryline, rich moisture and strong instability and unsettled southwest flow aloft provided the ingredients for the rounds of severe weather. After a reprieve from the storms in mid-May, the active weather returned in full force on Monday, May 20th.

The impetus to kick off the severe weather on Monday, May 20th, was a strong upper low approaching via the Four Corners. Thunderstorm erupted early in the day, primarily from the Texas Panhandle northward, but soon followed over the South Plains and Rolling Plains shortly after midday. The activity continued to redevelop and affect portions of the region through the evening, lingering into the late-night hours across the Rolling Plains. At least a few brief tornadoes formed from these storms, including one near McAdoo, another west of Paducah and one east of Dickens. Thankfully, these tornadoes occurred over open land and did no known damage.

The intense storms also generated damaging winds, large hail and torrential rainfall. The wind and golf ball size hail did considerable tree damage in and around south and east Lubbock during the afternoon, while hail as large as tennis balls fell east of Memphis. A wind gust as high as 80 mph was measured at the West Texas Mesonet located on the west side of Spur.

Several rounds of strong to severe storms then trained over the southern Rolling Plains well into Monday night. In addition to severe weather, these storms dropped very heavy rain that resulted in minor flooding in and around Aspermont.

The below map shows that the rainfall fell roughly along and east of the I-27 and US-87 Corridor, with the heaviest rain falling in a swath across the southeast half of Stonewall County. The West Texas Mesonet site near Aspermont recorded 3.17 inches of rain.

After a couple day reprieve, the active weather returned, with four straight days of severe weather in and around the South Plains over the Memorial Day Weekend.

Thursday, May 23rd, kicked off this active stretch as deep Gulf of Mexico moisture returned to West Texas, pushing well into eastern New Mexico early in the day. The dryline sharpened in the afternoon as it mixed into the western South Plains, and was the focus for scattered thunderstorm development. One storm spawned a brief anticyclonic tornado west of Brownfield, but the main impact from these storms were large hail and torrential rain.

Numerous spots saw hail as big as golf balls, while baseball size hail was reported near Shallowater and tennis ball size hail fell west of Floydada.

The slow-moving supercell thunderstorms repeatedly tracked across the central South Plains before spreading northeastward into the southeast Texas Panhandle. As they did so, the torrential rain, tallying to 1 to 3+ inches, caused flooding around the region.

The next day, Friday, May 24th, brought more of the same. This time the storms started early in the day, firing up just southwest of Lubbock before midday. This activity grew in coverage and intensity through the afternoon hours and persisted through much of the evening before finally diminishing late. To make matters worse, the thunderstorms trained over the same locations, dropping torrential rainfall as they did so.

The excessive rainfall quickly flooded Lubbock before expanding its horizons to engulf locations to the east-northeast, including Ralls, Floydada and Matador. Unfortunately, all of this rain did cause extensive flooding, with the runoff inundating many locations across the central South Plains for the second day in a row.

The focus for the nearly continuous thunderstorm development was a boundary left over from the previous day's activity that was reinforced by the outflows from the ongoing storms on the 24th. This boundary, visible in the below radar imagery, sat across the southern South Plains through the day, moving very little. Warm and very moist air south of the boundary advancing northward was continually lifted which resulted in the rapid thunderstorm redevelopment.

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.

From a distance, the storm activity was beautiful (see the above pictures), but the intense rainfall did cause a lot of problems. In addition, many locations again saw quarter to golf ball sized hail.

Rain totals from this day were impressive in a swath from the central South Plains into the far southeast Texas Panhandle where 2 to 4+ inches were common. Officially, the Lubbock Airport recorded 2.40" on this day, setting a daily rainfall record (the previous record was 2.18", set in 1937) and instantly catapulting the yearly rainfall above average (to 6.83", which is 1.27" above the average year-to-date total of 5.56").

The next day, Saturday, May 25th, was very active too, though the axis of storm shifted northward into the northwest South Plains and southern Texas Panhandle. More flooding rain and at least four tornadoes occurred, including a brief tornado that inflicted damage on the north side of Plainview.

The weather was quieter much of the following day, Sunday, May 26th, but quickly turned active in the evening as storms moved out of eastern New Mexico. The bulk of the activity affected the Panhandles, but one lone supercell tracked out of east-central New Mexico and across the northwest South Plains into the south-central Texas Panhandle. This storm produced a large tornado in New Mexico mid-evening, then went on to produce a few (or more) tornadoes as the storm tracked from east of Muleshoe to just north of Hart and Sunnyside, to north of Tulia, after dark.

The tornadoes flipped center pivots and downed power poles, but thankfully dodged most other structures dotting the rural countryside. One other brief tornado was observed from a different storm, rotating around the primary storm, as it passed near Lariat.

 

Radar-estimated, bias-corrected 3-day rain total ending at 7 am on Sunday, 26 May 2019.

Rainfall over the course of the extremely active late May stretch was more than generous for a large chunk of the South Plains, southeast Texas Panhandle and northern Rolling Plains, as the above graphic illustrates. Many locations record 3+ inches of rainfall. The heavy rainfall did cause a lot of problems, but it also added water to a few of the reservoirs in the region.
