654 pm cdt Fri aug 23 2019

Discussion Storms that persisted over the victoria crossroads
this afternoon are diminishing at this time. Isolated convection
will be possible early this evening along the sea breeze moving
inland over the brush country. Will mention slight chance of
thunderstorms early this evening but pops will be below 20
percent. Wind speeds are also stronger behind the sea breeze at
this time. Adjusted winds to scec across the gulf waters into the
southern bays for this evening. See aviaton section for 00z tafs.

Aviation Isolated convection will be possible near the inland
moving sea breeze early this evening before dying out. Gusty
southeast winds will move inland with the sea breeze this evening.

Higher moisture will remain over the gulf waters tonight and move
toward the mid-coast region before daybreak. MVFR ceilings and
isolated showers should affect the vct area from 10-14z Saturday.

Scattered convection will move into the victoria crossroads from
14-18z with MVFR ceilings persisting. Convection expected to be
more isolated over the coastal bend with MVFR ceilings expected
from 14-18z.VFR conditions will occur for the afternoon with
a chance for tsra in the vct area. Isolated storms will be
possible along the sea breeze in the coastal bend.

short term (tonight through Saturday night)...

convection over the region once again very limited across the
forecast area with most of the activity north into hgx area. A few
showers noted along the sea breeze, and could see a bit of an
increase in this yet this afternoon. So far no storms, but can't
rule that out through the afternoon. Most of the moisture
currently in the gulf of mexico is still progged to head northward
into the weekend, thus dont have pops on Saturday much higher than
what we're seeing today. Could again have a slightly more active
seabreeze, so do have 30 pops for the coastal bend. By tomorrow
evening an upper level shortwave over west to central texas will
provide a slight chance for showers storms for western zones.

Generally sticking with persistence for min temps, near seasonal
normals. MAX temperatures will also be similar tomorrow to what
we're seeing today, especially west. East and northeast could see
some cooler values if showers coverage is higher.

Long term (Sunday through Thursday)...

isolated to scattered rain chances continue across the coastal
bend plains and the middle texas gulf waters for Sunday and into
early next week. The best rain chances through the extended period
are expected to be on Sunday as the 12z model runs are progging a
bit higher pwats than yesterday with values ranging from 2.1 to 2.4
inches across south texas. In addition to the ample moisture, the
right entrance region of a fairly unimpressive 40-50 knots 250mb sub-
tropical jet setups up across the region on Sunday as a 500mb
shortwave trough pushes into central south texas from northern
mexico. The combination of copious moisture and upper-level dynamics
is expected to provide enough synoptic scale lift to support
isolated to scattered convection across most portions of south texas
through the day on Sunday. Like yesterday's model runs, today's 12z
gfs remains the most bullish with a prominent 500mb vorticity max
and DCVA associated with that shortwave. However, the 12z NAM does
not have as significant of a vorticity MAX as the gfs, but it is
still hinting at a more conducive DCVA than the ECMWF canadian.

Since GFS nam are beginning to align more with the shortwave trough
and higher moisture, confidence for slightly higher pops is
increasing a bit more for Sunday, but still have sided more along
the lines of the ECMWF canadian solutions for rainfall on Sunday.

For early part of next week, models prog the mid-level ridge to
build eastward with the eastern extent of the ridge setting up over
texas. Subsidence from the ridge will likely result in drier
conditions through the layer with lower environmental moisture
through the week. However with moisture mainly confined near the
surface, pwats are still expected to remain around 1.8-2.0 inches,
which combined with lift from the afternoon sea breezes will likely
support isolated shower activity each day through the week.

As for south texas temperatures, can expected hot and humid
conditions with highs ranging from near 90 degrees along the coast
to mid 100s degrees out west and overnight lows in the upper 70s to
low 80s through the extended period. As the ridge continues to build
in across the region through next week, can expect a bit warmer
temperatures by Monday and Tuesday. With the persistent summertime
pattern, heat indices will range between 105-114 degrees with sps's
likely to be needed through Monday, while heat advisories may be
needed by mid-week.

Marine...

showers and thunderstorms are expected tonight into Saturday
through the coastal waters as a disturbance moves northward.

Summertime pattern continues across the middle texas coastal
waters with weak to moderate onshore flow persisting through early
next week. Could see slightly more moderate winds Sunday & Monday
afternoons for the southern nearshore waters resulting in scec
conditions. Lingering moisture across the area waters will
contribute to scattered showers and thunderstorms Sunday. As high
pressure builds in early next week, moisture is progged to
slightly decreases and result in mostly isolated convection
through next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
