What happened

The episode as NWS LUB wrote it up.

Hot temperatures on the afternoon of the 11th slowed down a cold front moving through the area but also provided a focus for thunderstorm development. Strong instability, resulting from the warm temperatures and high moisture, ahead of the front fueled the rapid development of severe thunderstorms from the late afternoon into the evening hours. Thunderstorms initially developed over the extreme southeastern Texas Panhandle and northern Rolling Plains where temperatures in excess of 100 degrees allowed updrafts to break through a capping inversion. Atmospheric flow was weak which allowed storms to move slowly and create torrential rainfall in some locations. Some roads within the city of Levelland (Hockley County) became impassable because of water over the road. The most significant thunderstorm developed over southern Lubbock County and moved southward producing severe wind gusts and wind damage throughout Lynn County. These winds caused minor but widespread damage throughout the towns of Tahoka and Wilson.

What forecasters said that day

.SHORT TERM...
(This evening through Friday)
Issued at 1224 PM CDT Thu Jun 11 2026

The cold front has entered our southwestern zones as of noon and is
continuing to push southward, though at a somewhat reduced but still
relatively quick speed from this morning. The front is expected to
be halfway through the FA by this evening with the timing of the
front possibly putting the current forecast high temps in jeopardy on
the Caprock. Convection is expected to develop along the front by
late afternoon with the highest chances favoring the Rolling Plains
with the area of greatest surface convergence. A weakness in the
upper ridge will help to initiate convection. Convection should
dissipate after sunset as surface heating is lost, but a weak LLJ
could help sustain some weak convection to midnight or just beyond.
Shear will be relatively weak, 20 knots to a max 30 knots, and will
help to limit the overall severe threat. Despite this, some storms
will be capable of producing 2 inch hail and wind gusts up to 70 mph.

Any convection still ongoing after midnight should dissipate by
sunrise Friday. A surface lee trough will bring winds to the south
Friday afternoon as the upper ridge builds slightly over the region.
Despite the slightly stronger ridge, Friday afternoon highs will be
much cooler than today thanks to lingering effects of the cold
front. Convection is expected to develop across the higher terrain
of New Mexico during the afternoon but is not expected to move into
the FA before surface heating is lost and storms dissipate. There is
the slim chance for a decaying storm to move into our northwest
zones after sunset and a slight chance mention has been retained.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 1224 PM CDT Thu Jun 11 2026

A somewhat wet forecast remains in store this weekend through early
next week. A second cold front is progged to push through the Texas
Panhandle by Saturday afternoon and into the FA by early Sunday.
This will be another passive front with little upper support and
will struggle to make it to our southern zones. Ample moisture and
weaknesses in the upper ridge to our south will aid surface
convergence along the front for convective development. The overall
threat for severe storms remains low with bulk shear maxing out at
25 knots or less, though wind gusts over 60 mph will still be
possible. The main threat will be flash flooding especially if the
forward progression of the front stalls and storms begin to train.
Upper flow will become more northwesterly Monday and will help push
the cold front south of the region and precip chances with it. The
forecast mid to late week then looks to be rather quiet yet warm.
Surface lee troughing will keep surface winds out of the south to
southeast. While this will help us hold on to surface moisture, an
overhead upper high will keep most precip chances at bay, though
some widely isolated diurnal storms will not be out of the
question.

.AVIATION...
(00Z TAFS)
Issued at 610 PM CDT Thu Jun 11 2026

A cold front was currently slowly moving southward through the
region. This front is expected to move through KLBB within the
next hour or two which will shift winds to the northeast and
increase in speeds a bit. Isolated thunderstorms have developed
along portions of the front with the greatest activity near KCDS.
Chances of thunderstorms near KLBB and KPVW is rapidly decreasing
late this afternoon, therefore, no mention was made in the TAF of
thunderstorms at these two TAF sites.
