April 5-6, 2019: Severe thunderstorms and heavy rain impact the South Plains

Strong thunderstorm developing south of Lubbock Friday evening (5 April 2019).

Lift from the approach of a potent upper level disturbance caused thunderstorms to erupt over West Texas Friday evening (5 April). Initially, low level moisture was on the meager side and this limited both the coverage and rainfall efficiency of the storms. As the moisture and instability increased through the evening and overnight hours, so did the thunderstorm coverage and intensity. Several rotating storms and clusters of storms generated hail, gusty winds and very heavy rainfall.

Nickel size hail was observed in Lubbock, along with numerous reports of pea sized hail. To the southeast, a different storm dropped half dollar sized hail near Justiceburg. The hail-producing storms were also accompanied by brief periods of very heavy rain.

GOES 16 visible satellite loop valid from 5:58 pm to 6:05 pm on 3 April 2019.

GOES 16 water vapor satellite loop valid from 7:56 pm to 9:21 pm on 5 April 2019. A close-up infrared loop valid from 9:07 pm to 9:22 pm can be SEEN HERE.

As lift continued to increase through the late evening hours, the thunderstorm activity became more widespread while expanding into the Rolling Plains. Several intense storms tracked repeatedly over the southern Rolling Plains bringing torrential rainfall and swaths of hail and damaging winds.

Lubbock radar animation valid from 11:23 pm to 1:13 am on 5-6 April 2019. Additional regional animations can be view at: 11:38 pm to 12:48 am; 1:48 am to 2:58 am; and 4:38 am to 5:48 am.

Unfortunately, Jayton was on the receiving end of the more intense activity. One storm brought strong winds that toppled trees and damaged buildings. The rounds of storms also dumped an impressive 4 inches of rain in town, which lead to some flooding problems.

The showers and thunderstorms continued through much of the night off the Caprock before finally winding down Saturday morning. The below image displays the estimated rainfall for this early April event. A corridor of 2.5+ inches of rain fell over southeast Garza County eastward into Kent and King Counties. Rain totals were lighter in Lubbock, generally from around a quarter to half inch, with the Airport officially recording 0.24 inches. Childress officially recorded 0.87 inches early Saturday morning.

24-hour radar-estimated and bias-corrected rainfall totals ending at 6 pm on 6 April 2019. The rain totals measured by the West Texas Mesonet sites can also be SEEN HERE.

The heaviest core of rain fell over and just upstream of Lake Alan Henry, across southeast Garza County. Runoff from the heavy rain caused the Brazos River near Justiceburg to rapidly rise to action level early Saturday morning before decreasing almost as fast. This water poured into Lake Alan Henry causing it to rise about a foot and a half.

Severe thunderstorm over northern Childress County on Wednesday evening (3 April 2019). The picture was captured by Alex Spahn.
