Late April and early May 2019 brought a few rounds of severe weather to West Texas. The activity was triggered by daytime heating along with a couple of passing cold fronts and upper air disturbances, while being fueled by good amounts of moisture and instability. The initial round of severe weather was sparked by a cold front dropping through the South Plains on Saturday, 27 April.

Scattered thunderstorms developed along and immediately behind the cold front Saturday afternoon. The strongest storms dropped large hail and heavy rain as they moved eastward across the Rolling Plains through the evening hours.  Hail as large as baseball size was observed near Jayton as well as west of Swenson, where a car had its windshield broken. The Jayton West Texas Mesonet also recorded a wind gust to 63 mph.

As the storms merged into one larger complex in the southern Rolling Plains, one tornado (pictured at the top of this page) briefly touched down between Jayton and Aspermont (just west of Peacock). Thankfully, the tornado was over rural land and did no known damage before dissipating.

Below are a couple of pictures showing the impressive storm development, as well as the damage that the hail inflicted on the flora of the Rolling Plains.

The more intense activity did also drop heavy rain, with the highest rainfall totals falling in a swath from near Spur down to around Aspermont. This quick shot of rain did cause some minor flooding problems in and around Spur.

After a couple of quiet weather days, the weather turned more active again Tuesday afternoon and evening (30 April). This activity was sparked by a lifting warm front and approaching dryline and upper level trough.

Widely scattered thunderstorms developed along the warm front sitting across the southern Rolling Plains during the afternoon, while additional activity fired along the dryline across the western South Plains. All of this activity moved eastward through the late afternoon and evening hours. A couple of these storms did acquire mid-level rotation, which helped to increase their intensity and generate large hail.

Hail as large as golf balls was observed south of Jayton, west of Littlefield and near Cotton Center. Even larger hail, measured as big as 2.1" diameter, was measured near Aiken, not far from Plainview.

Below are a couple of different views of the severe thunderstorms that tracked across the South Plains and Rolling Plains Tuesday afternoon and evening.

The below radar imagery shows the two most intense storms of the day clearly. The first was the storm that formed near the warm front and tracked across southern portions of Garza, Kent and Stonewall Counties. The other long-duration supercell was a storm that developed west of Littlefield and then tracked steadily eastward through the late afternoon and evening hours, eventually affecting locations between Childress and Paducah.

Tuesday's round of thunderstorms brought additional swaths of heavy rainfall to the region. As one might expect, the highest rain totals, near and above an inch, were associated with the two strongest storms of the day. Even outside of the thunderstorms, many locations did receive light rain totals thanks to early day drizzle, showers and thunderstorms. In fact, one early morning storm briefly became severe as it lifted into the south-central Texas Panhandle. A radar animation of the early day activity, valid from 7:27 am to 9:10 am, can be FOUND HERE.

The following day (Wednesday, 1 May 2019) the main action area shifted eastward, with the southern Rolling Plains on the western edge of the thunderstorm activity. Storms exploded along a lingering frontal boundary that clipped southern Stonewall County early Wednesday afternoon.  Very strong instability supported quick intensification and a fast transition to supercell thunderstorms.

Very large hail likely fell with the most intense storms over rural parts of Stonewall County, though we only received verification of golf ball size hail east of Aspermont. In addition, one rotating storm did produce a low-hanging wall cloud as it moved just east of Aspermont, though no known tornado. However, a couple of tornadoes were reported not too far away, one southeast of Haskell and a second north of Throckmorton.

Even as the storm intensity eased through the evening hours, thunderstorms continued to regenerate over portions of Stonewall County, producing rounds of heavy rain there. A couple of inches or more rain fell over the southeast corner of Stonewall County generally near and south of Old Glory, creating flooding concerns there.
