The episode as NWS CRP wrote it up.
A broken line of thunderstorms developed over south-central Texas during the early morning hours. The storms developed along a cold front with the storm development aided by an upper level disturbance moving across south Texas. The storms produced wind gusts between 55 and 65 mph. Wind damage occurred in Laredo. The storms produced locally heavy rainfall that led to flooding in Laredo and Corpus Christi.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Apr 23, 5:33 AM CST, 3 hours 2 minutes earlier.

...New UPDATE, AVIATION...
.UPDATE...
Issued at 625 AM CDT Sun Apr 23 2023
Severe Thunderstorm Watch is in effect for the entire area until 2
PM. Mesoscale convective system developing to the northwest is
expected to surge southeast through the region this morning. Did
adjust high temperatures up slightly as cold front a little slow
to move into the region.

.SHORT TERM...
(Today through Monday)
Issued at 429 AM CDT Sun Apr 23 2023
Key Messages:
- Severe storms mainly this morning with damaging winds and hail
expected
- Locally heavy rainfall possible mainly this morning
- Minor coastal flooding today and possible again Monday
- High risk of rip currents today through Monday
Convection has increased in coverage in region between Del Rio and
Eagle Pass ahead of the cold front pushing southward out of the
Hill Country early this morning. Axis of strong instability with
MUCAPE of 1500-2500 J/kg extends southeast from the Rio Grande
plains toward the Middle and Lower Texas coast. Hi-res models are
in agreement this developing mesoscale convective complex will
surge southeast ahead of the cold front during the morning hours.
Appears the threat for damaging winds will be higher with this
system mainly during the morning hours, but hail will also be
possible. With the amount of low level shear, the threat for
tornadoes is there as well. With the amount of moisture in place,
locally heavy rainfall is still possible but the threat for
excessive rainfall will be mainly this morning. High rain rates
will cause drainage problems for urban areas.
Expect lingering showers with possibly embedded storms to be
possible from this afternoon through tonight behind the cold
front. Adequate moisture will remain over the region with weak
isentropic lift to keep the chance for showers in the forecast
for Monday.
A strong easterly flow will lead to an increase in swells today.
Tide levels are already increasing and running about 1 foot above
expected at this time. A Coastal Flood Advisory is in effect for
the islands until 21Z today. With the long period swells and east
winds today and northeast winds tonight and Monday, there will be
a High risk of rip currents today through Monday for Gulf-facing
beaches.
&&
.LONG TERM...
(Monday night through next Saturday)
Issued at 429 AM CDT Sun Apr 23 2023
The NAM/ECMWF predict an upper level disturbance to move EWD across
the CWA Tuesday, and the ECMWF/GFS predict another upper system
to move across the region from the northwest Wednesday night/
Thursday. Expect the combination of upper forcing associated
with the first system, sufficient moisture, and instability, to
contribute to isolated/scattered convection, mainly over the Coastal
Plains (limited CAPE/significant CIN over the western CWA per the
GFS deterministic run) Tuesday. The combination of the next upper
system, the corresponding frontal boundary, and sufficient moisture
may result in isolated/scattered convection Wednesday night/early
Thursday (Although the GFS predicts significant CIN in advance of
the front which may limit convection, this NWP model predicts
significant elevated instability which can combine with upper
forcing to generate at least elevated convection.) Drier Thursday
night/Friday. The GFS/ECWMF predict a third upper system/associated
frontal boundary to provide upper/surface forcing to the CWA Friday
night/Saturday. The GFS/ECMWF predict sufficient moisture in advance
of the front. However, the GFS predicts thermodynamic profiles
unfavorable for convection, with a moderate/strong CIN (surface-
based parcels not likely to reach their LFC) and limited
instability aloft (decreased risk for elevated convection).
Thus, will forecast mostly cloudy skies for Saturday owing to
moisture convergence along the front, yet will not introduce
precipitation (the NBM adds credence with PoPs of less than 10
percent over the CWA.) P-ETSS suggests that water levels may reach
coastal flooding Tuesday, yet not Wednesday.

.AVIATION...
(12Z TAFS)
Issued at 632 AM CDT Sun Apr 23 2023
MVFR ceilings are prevalent over most of the region early this
morning. Isolated convection has formed over the Victoria
Crossroads at this time. Storms over the northern Rio Grande
plains ahead of the cold front is expected to increase and expand
as they move to the southeast into an unstable air mass. Expect
storms into the Brush Country 12-14Z and the coastal plains
between 14Z-18Z. Ceilings will fall to IFR as storms move through
the region. MVFR to IFR vsbys along with strong to severe wind
gusts expected to occur as the convective complex surges toward
the coast during the morning hours. Hail will be possible with the
stronger storms. Showers will continue behind convective complex
and front into the mid afternoon hours over the coastal plains
with generally MVFR ceilings continuing through this evening.
Will show IFR ceilings south to MVFR ceilings north from late this
evening during the overnight period behind the front.
&&
.MARINE...
Issued at 429 AM CDT Sun Apr 23 2023
A strong easterly flow will occur this morning then shift to the
northeast during the afternoon behind a cold front. SCA is in
effect for the Gulf waters until 10Z Monday. Numerous showers and
thunderstorms are expected to move into the coastal waters later
this morning. Storms will be capable of producing strong wind
gusts and hail. The moderate to strong northeast flow will
continue through the night into Monday.
Isolated to scattered showers/thunderstorms anticipated for Monday
night/Tuesday, in response to an upper level disturbance. Another
upper system/associated frontal boundary may generate
isolated/scattered convection again Wednesday night/Thursday. Drier
Thursday night/Friday. A third upper system/associated frontal
boundary is predicted to enter the region by Saturday. However,
unfavorable thermodynamics (GFS deterministic) may preclude
convection.
