.SHORT TERM...
(Today through Sunday)
Issued at 226 AM CDT Sat Apr 27 2024

Key Messages:

- High risk of rip currents through tonight

- Minor coastal flooding likely today

- Strong winds expected today. A Wind Advisory is in effect from
  10 AM through 7 PM

- Isolated to scattered showers tonight and Sunday

While not expected, there is a low chance of isolated showers
today due to an upper level disturbance. A surface low pressure
will develop today, resulting in a strong onshore flow. A Wind
Advisory is now in place from 10 AM through 7 PM across the
Coastal Bend and Victoria Crossroads. The pressure gradient will
eventually shift to the west this evening, which could lead to
Wind Advisory conditions over the Brush Country.

An upper level trough will move across the area Sunday combining
with abundant moisture and moderate instability to produce
a 20%-50% chance of showers and thunderstorms over the northern
Brush Country and Victoria Crossroads. The Storm Prediction Center
has included these areas in a Marginal Risk for severe weather,
though I suspect it is more likely that strong storms will move
down into South Texas from the Hill Country rather than develop
over our area due to a capping inversion.

Strong onshore flow today will lead to several hazards across the
Middle Texas Coast. First, a combination of strong winds and long
period swell will lead to minor coastal flooding along Gulf
facing beaches. These conditions will also lead to a high risk of
rip currents along Gulf facing beaches today through tonight.

.LONG TERM...
(Sunday night through next Friday)
Issued at 226 AM CDT Sat Apr 27 2024

Key Messages:

- Low chance of showers and thunderstorms expected this week

- Minor coastal flooding possible through midweek

While a series of shortwaves will keep a low (15-30%) chance of
showers and thunderstorms in the forecast daily through the
upcoming week, things will remain relatively quiet for the long
term forecast. Winds will weaken Sunday night, with a weak to
moderate onshore flow persisting. Temperatures will be warm with
highs in the mid 80s across the east to the mid 90s across the
west.

With persistent moderate to strong southeasterly flow through the
weekend, long period swells, and large sea states, minor coastal
flooding along Gulf-facing beaches is possible during times of
high tide. This risk could continue through the middle of the week
before swell periods begin to decrease, diminishing the chances.

.AVIATION...
(06Z TAFS)
Issued at 928 PM CDT Fri Apr 26 2024

MVFR CIGS have set in for eastern sites and will persist through
the night. Western sites should have a period of MVFR CIGS toward
morning.  Winds remain elevated, especially at CRP where gusts of
20 kt likely continue through the night. CIGS improve again by
mid-day Saturday. Winds should subside to more moderate levels for
western sites, but farther east gusts above 30kt are likely
again.

.MARINE...
Issued at 226 AM CDT Sat Apr 27 2024

Strong onshore flow with occasional gusts to 35 knots remain
likely through Sunday. Seas will remain elevated through Monday
morning, so the Small Craft Advisory has been extended through
Monday morning. Isolated showers and thunderstorms are possible
late tonight and Sunday morning. The strong onshore flow will
weaken through Sunday night. Weak to moderate onshore flow is then
expected to persist from Monday morning through the upcoming
week. Isolated to scattered showers and thunderstorms are expected
through the upcoming week.
