The episode as NWS CRP wrote it up.
Much needed rainfall occurred over the Coastal Bend of south Texas on August 14th and 15th as an area of low pressure, that formed over the northwest Gulf of Mexico, moved inland. The low pressure area was close to becoming a tropical depression and the National Hurricane Center designated the system invest 98L. Bands of heavy tropical rainfall moved across Corpus Christi from the late morning into the middle of the afternoon. Locally heavy rainfall produced flooding of roadways across the city. Another band of showers moved across the same region during the early morning hours of the 15th. This caused flooding of roads again in Corpus Christi.

(Today through Monday)
Issued at 420 AM CDT Sun Aug 14 2022
The GFS/ECMWF generally agree with the timing/position of the 500-mb
upper low, moving it slowly westward across the CWA today/tonight,
with N-S axis west of the Rio Grande by 12z Monday. The GFS/NAM
continue to maintain very moist conditions over the CWA during the
period. Most recent MSAS depicts the corresponding surface trough
axis along the coast, with a closed low centered near Kleberg
county. SREF mean MSLP/10-m wind depict the surface trough to move
slowly westward this morning. Numerous/widespread showers and
scattered thunderstorms are expected today, along with locally
heavy rainfall. The NAM suggests that environmental conditions
will be favorable for efficient rainfall production over the
southern Coastal Plains today. Most recent HREF output indicates a
40-65 percent chance for greater than 3 inches of rain in the
12-15z period this morning, compared with a 4-5 inches/3 hr FFG
from the RFC. After coordinating with WFO BRO, decided not to
issue a FFA and defer to the day shift to consider the flash flood
risk. Although localized flooding can occur, it is difficult to
predict whether widespread flash flooding will occur given the
ongoing precipitation drought. Additional convection expected
tonight/Monday, yet the greatest chance for convection will shift
to the central/western CWA owing to the expected position of the
upper/surface forcing.

(Monday night through Saturday)
Issued at 420 AM CDT Sun Aug 14 2022
-There's a Marginal to Slight risk of excessive rainfall Monday
Night along the Rio Grande as a mid-level trough move into
northeast Mexico.
-Rainfall chances continue through the end of the week in response
to mid-level disturbances and abundant moisture interacting with
the seabreeze.
-Heat Index values of 105-109 return around mid-week
The mid-level low will be centered over Coahulla Mexico to start the
period Monday evening with a deep southeasterly low level jet of 30
kts fueling higher moisture advection and the potential for locally
heavy rain/localized flash flooding along the Rio Grande during the
overnight hours. Flash flooding would primarily be confined to areas
with poor drainage and urban settings. Heavier precipitation will
gradually shift west into Mexico late Monday Night as the low moves
farther away.
Will maintain a chance for showers and thunderstorms across the
region on Tuesday as weak broad trough persists aloft with adequate
moisture. Looks drier on Wednesday as mid level ridge builds over
the area. Expect only isolated showers at best.
Rain chances increase late Thursday and continuing into next weekend
as a mid level trough and associated surface boundary approach the
region from the north. At the same time, an inverted trough in the
NW Gulf is progged to move into deep South Texas bringing deep
tropical moisture with PWs near 2.5" once again. Will need to
monitor the trends with this system, but its a positive sign and
would certainly help increase our ground moisture.
Expect Heat index values of 105-109 degrees beginning on Tuesday and
continuing much of the week.

(18Z TAFS)
Issued at 1215 PM CDT Sun Aug 14 2022
As an area of low pressure pushes west across the area, prevailing MVFR
ceilings are expected. Numerous showers will continue through
tonight, with scattered thunderstorms possible. Winds will
continue to be light to moderate, with variable and gusty winds in
and around thunderstorms. Ceilings will decrease to IFR late in
the TAF period and during periods of heavier rainfall.

.MARINE...
Issued at 420 AM CDT Sun Aug 14 2022
An upper level disturbance and copious moisture will contribute
to convection today. Isolated to scattered showers/thunderstorms
Monday owing to lingering moisture. Generally moderate onshore
flow today in response to the surface low/trough developing just
inland. Weak to moderate onshore flow Monday. Expect mainly
isolated showers and thunderstorms for the remainder of the week.
Weak to moderate onshore flow will persist through the period.
However, winds and seas could be higher near thunderstorms.
