Discussion See aviation section for 00z tafs.

Aviation Most of the convection along the sea breeze has
dissipated at this time, except for some isolated showers drifting
toward laredo. These showers may linger for another hour or two.

Otherwise, winds will diminish over the coastal plains while
staying a little elevated over the brush country this evening.

Vfr conditions will continue through the evening hours into
the overnight period. With light winds over the inland coastal
plains, patchy fog will be possible with MVFR vsbys from 10-14z.

Adequate low level moisture could lead to spotty MVFR ceilings
near lrd again around daybreak Thursday. Isolated showers will
move into the coastal areas to the victoria crossroads Thursday
morning. Isolated to scattered showers and storms are expected
again near the sea breeze mainly in the vct area.

short term (tonight through Thursday night)...

showers and thunderstorms continue to develop and push across the
victoria crossroads and the middle texas coastal waters this
afternoon. As we lose daytime heating and the environment becomes
more stable, this activity should subside through the evening.

However, there will still be isolated rain storm chances mainly
for the middle texas coastal waters overnight into Thursday
morning. Otherwise, will be another warm and muggy night across
south texas with partly cloudy skies and lows in the mid 70s to
low 80s.

With a progressive meridional pattern across the conus, the mid-
level ridge's influence over south texas diminishes a bit more.

Temperatures on Thursday will be closer to normal, but still a
degree or two above with highs near 90 along the coast to near 102
degrees out west. Additionally, more moisture is progged to advect
into the area as an inverted trough weak tropical wave begins to
push into the western gulf of mexico through Thursday. This wave
will help bring higher moisture into the region and lead to
increased rain chances through the short-term period. Pwats across
south texas are expected to range from 1.8-2.0 inches, which
combined with the afternoon sea breeze will fuel isolated to
scattered shower thunderstorm activity Thursday afternoon and
diminishing through the evening. However, with the ample moisture
continuing to filter into the region, rain chances will persist
into early Friday morning ,especially across the middle texas
coastal waters.

Long term (Friday through Tuesday)...

general pattern for the extended forecast is for our summertime
ridge to drift northward just far enough for a weak trough to drift
westward under the ridge across the northern gulf. Moisture is
expected to return to the area along the trough, but models continue
to indicate that the majority of the moisture will remain over the
gulf waters. Pwats should increase to around 2.3 inches on Friday,
before backing off slightly over the weekend. This should allow for
some seabreeze convection through the weekend and into the first
part of next week.

Models continue to advertise a bit of upper support for activity
over the western brush country Sunday and Monday. GFS continues to
be more aggressive with this activity than other medium range
models, and so will continue to undercut GFS pops through the
remainder of the extended period.

Temperatures will remain warm, but increased cloud cover may allow
for a trend more towards normal through the weekend and early next
week. Humidity will remain high, and heat indices will continue to
peak between 105 to 109 across much of the coastal bend.

Marine...

scattered showers are currently making their way across the middle
texas coastal waters this afternoon and are expected to diminish
through the evening before developing again overnight. Otherwise,
weak to moderate onshore flow will continue through the weekend
and into early next week. Increasing chances of showers and
thunderstorms are expected through Saturday, before gradually
diminishing early next week.
