.DISCUSSION...
Issued at 119 AM CDT Thu May 21 2026

At the time of writing this discussion, yet another nocturnal MCS is
slowly progressing through South Texas (this is the third night
in a row). This morning's MCS is more of the prototypical late
spring eastward propagating system from Mexico, riding just ahead
of a convectively-enhanced shortwave. Instability is less
impressive than last night (MLCAPE around 2000 J/kg, DCAPE 900 to
1000 J/kg), but should be enough to support MCS maintenance as it
treks through the area. If the system is able to form and sustain
a robust cold pool, strong winds would be a convective hazard,
otherwise as mentioned in previous discussions hydro will likely
be the biggest concerns. One hour FFGs are as low as 2-2.5 inches
(and 3 hour FFG < 3 inches) over portions of the Brush Country and
Coastal Plains, so those in particular will be areas to monitor
early this morning.

Although the CAM suite has had a lot of issues timing the
progression of this system, based on current radar trends and
assumed system propagation, would expect precipitation to more or
less have cleared the area by 11-14Z. Similar to the last couple
days, the combination of post MCS low-lvl stabilization and weak
subsidence will somewhat limit precipitation chances during the
daytime hours. However, there is some signal for another trailing
wave during the afternoon hours, so will retain some low-medium
range PoPs (20-40%), but am pretty skeptical of the widespread
coverage some of the CAMs and the GFS depict (the storms would
likely have to initiate north of the area which is less worked
over). We will potentially have to contend with additional
overnight convection tonight into Friday morning as more storms
developing over Mexico and the West Texas dryline and gradually
propagate towards our area. There is a more muted convective
signal compared to the last couple nights, so will retain only
Chc (generally 40-50%) PoPs for now, but any additional convective
rainfall would trigger renewed hydro concerns given antecedent
conditions.

The most-amplified mid-lvl wave is still progged to move over the
area on Saturday, likely bringing fairly widespread rainfall to
the area. Hydro will likely be the greatest concern by that
point, and beyond the localized flash and urban flooding threat,
river flooding will also bear increasing monitoring. The
aforementioned mid-lvl low looks to amplify/close off near the
area on Sunday and then lift slowly to the north/northeast on
Monday/Tuesday. This could provide a setup to give us a brief
respite from the active weather as drier air filters down its
western flank from the north. Any break in precipitation looks to
be short-lived as another mid-lvl system makes it way towards the
area mid to late next week.

.AVIATION...
(06Z TAFS)
Issued at 119 AM CDT Thu May 21 2026

An ongoing cluster of showers and thunderstorms over the Rio Grande
Plains will continue to slowly shift eastward through the early
morning hours. We'll likely have a mix of VFR/MVFR ceilings through
15-16Z as convection throws a wrench in the forecast. Heavy
thunderstorms directly impacting terminals will cause reduced
visibility and potentially strong variable winds. VFR conditions
prevail by midday with variable winds becoming predominately out of
the southeast at around 10 knots in the afternoon.

&&

.MARINE...
Issued at 119 AM CDT Thu May 21 2026

Generally gentle to moderate E-SE winds will prevail through the
weekend over the waters. The main exception to this will be brief
periods of erratic and gusty winds (and elevated seas) in the
vicinity of thunderstorms. Thunderstorm chances remain high
(60-80%) today, Saturday and Sunday, with Friday have somewhat
lower rain chances (20-40%).

&&

.FIRE WEATHER...
Issued at 119 AM CDT Thu May 21 2026

No fire weather concerns through the week as moisture increases
and minimum RHs remain over 50% area-wide. Medium to high rain
chances (50-80%) are expected each day through Saturday. These
should be solid wetting rains with aerial totals in the 2 to 4
inch range through the weekend.
