...New UPDATE...
.UPDATE...
Issued at 948 AM CDT Wed Apr 24 2024
Expect mostly cloudy, warm and humid conditions across South Texas today
as a mid level ridge builds overhead. The onshore flow will
gradually increase to moderate levels through the afternoon as low
pressure deepens over the Central Rockies. This will draw mid 70
dewpoints into the region resulting in more humidity. The strong
capping inversion at the H85 level will keep clouds around much of
the day. Although by late afternoon skies should become partly
cloudy as some drier air seen on visible satellite mixes in at
low levels. It should be noticibly warmer today -vs- yesterday
with temperatures warming into the mid 80s (east) to mid 90s
(west). This is about 5-10 degrees higher than yesterday. Current
forecast is on track and no changes are anticipated.

.SHORT TERM...
(Today through Thursday)
Issued at 331 AM CDT Wed Apr 24 2024
Deterministic models predict a slowly progressive pattern over
the CONUS during the period, with an upper level ridge (with N-S
axis) is expected to move eastward across the central CONUS
(including TX) today, while an upper level disturbance enters the
west coast tonight then approaches the Four Corners region
Thursday. Although above normal PWAT values are expected to
persist over the CWA during the period, no significant
precipitation expected owing to significant CIN/subsidence today,
and greater CIN Thursday. In response to the foregoing upper
disturbance to the west, breezy/windy conditions are expected over
the CWA Thursday afternoon. Yet, Elevated fire weather conditions
are not expected due to elevated relative humidity values. The
nearness to the full moon and increasing onshore wind speeds will
contribute to a Moderate risk of rip currents Thursday. Will
retain the NBM maximum temperatures today/Thursday over the CWA,
which are slightly warmer than both the HREF and SREF ensemble
mean values.

.LONG TERM...
(Thursday night through next Tuesday)
Issued at 331 AM CDT Wed Apr 24 2024
Key Messages:
- Medium to high chance of patches of Wind Advisory conditions
Thursday night into Friday.
- Very warm on Saturday with highs nearing the triple digits out
west.
Not much of a change from previous Extended forecast package. A
series of mid to upper level disturbances will combine with pockets
of above normal moisture to provide a slight chance (20-30%) for
showers and thunderstorms Friday and again Sunday through Tuesday. A
few frontal boundaries will also accompany the upper level systems
Friday and Sunday, but these will generally only make it into
portions of the Rio Grande Plains. Aside from this, the main hazard
through the long-term range is a strong southeasterly flow
developing and leading to brief periods of Wind Advisory conditions
over portions of the Brush Country Thursday night and across the
Coastal Bend and Victoria Crossroads on Friday. Winds are also
forecast to be elevated across the coastal waters through the entire
cycle leading to SCEC to SCA conditions. Otherwise, expect
increasingly warmer temperatures into the weekend with a medium
chance (50%) of maximums exceeding 100 degrees across the west on
Saturday, or 95 degrees or above daily through Tuesday.

.AVIATION...
(12Z TAFS)
Issued at 641 AM CDT Wed Apr 24 2024
Expect a mixture of MVFR and VFR ceilings this morning through
early afternoon, followed by prevailing VFR conditions. Expect an
approximately 03-06z Thursday transition to predominate MVFR
ceilings. Weak to moderate onshore flow this morning/early
afternoon followed by breezy conditions during the late
afternoon/early evening hours. A transition to weak to moderate
flow expected overnight.

.MARINE...
Issued at 331 AM CDT Wed Apr 24 2024
Weak to moderate onshore flow expected today and tonight.
Generally moderate onshore flow will develop Thursday afternoon,
as an upper level disturbance approaches the southwestern United
States. Onshore flow is forecast to strengthen to moderate to
strong levels Thursday night, with periods of Small Craft Advisory
or Caution conditions persisting through Sunday. Winds will
weaken into more moderate levels Sunday night and into weak to
moderate by Monday. Isolated showers and thunderstorms will be
possible daily Sunday through Tuesday as a weak disturbance moves
over the area.
