Synopsis for the middle texas coastal waters.. Isolated to scattered showers and Thunderstorms are expected through the weekend, with most of the rainfall activity occurring during the overnight and morning time frames. Weak to moderate onshore flow will persist over the weekend into next week. Rain chances will increase by early next week as an upper level disturbance moves north of the area and frontal boundary sinks southward across the state.

See aviation below for 12z TAF update.

Aviation
Light patchy fog and areas of MVFR CIGS are impacting terminals
across the region early this morning. Anticipate fog to clear by
the mid morning, with the MVFR CIGS at lrd lingering into the late
morning. Amd not sked at lrd due to ongoing connection problems
with observations at terminal. Streamer showers moving onshore
will remain in the vicinity of crp and vct this morning. Isolated
sea breeze convection will be possible later this afternoon, but
at the time believe coverage will be too limited to mention in
tafs. By the afternoonVFR should prevail at all terminals. A
light to moderate southeast wind will develop this afternoon. Late
in the period more patchy fog and MVFR cloud deck may develop
over vct and lrd respectively.

Previous discussion issued 437 am cdt Sat sep 23 2017
short term (today through Sunday)...

latest goes-16 pwat imagery shows higher plume of moisture remains
over the region with pwats of 1.7-1.9 inches. South texas will
remain under a ridge axis positioned between the deep upper level
trough over the rockies and a weak cut-off low over the southeast
us and northeast gulf of mexico. Given available moisture across
the region, expect a repeat of isolated to scattered streamer
showers moving onshore during the early morning and sea breeze
convection across the region in the afternoon. On Sunday the weak
upper low will move eastward along the northern gulf coast.

Although moisture will be slightly lower, provided the proximity
of the low, anticipate more scattered convection across the region
on Sunday, mainly across the coastal areas and victoria
crossroads.

Temperatures over the weekend will be fairly persistent, with
highs in the lowers 90s across the coastal bend to mid to upper
90s across the rio grande plains, and lows staying in the 70s
overnight.

Long term (Sunday night through Friday)...

main weather issues in the long term will be chances for showers and
thunderstorms. Moisture will remain plentiful through much of next
week with pw values generally at or slightly above 2 inches. To
start the period, large scale upper trough will be situated to the
west of the area. On Monday, shortwave trough rounding base of
trough and the sea breeze will combine to produce isolated to
scattered showers and thunderstorms over the area. The inherited 30
pops look reasonable at this time. Main upper trough ejects into the
northern plains Tuesday and great lakes on Wednesday. However, upper
low detaches from main trough and cuts off over the SW CONUS and
four corners region. An active southwest flow aloft will warrant
keeping a 40 percent chance of showers and thunderstorms in the
forecast on Tuesday. A frontal boundary will eventually move
southward across the state Wednesday and perhaps into the area on
Thursday or Thursday night. Current thinking is that rain decent
rain chances should continue Wed thu, but will not go as high as
superblend values just yet. One caveat will be how upper level ridge
behaves and whether or not it shifts back over parts of south texas.

Lingering rain chances may continue into Friday before diminishing
as drier air filters into south texas.

Regarding temperatures, highs above normal early in the period will
be set back to near or below normal as the week progresses due to
increased cloud cover and rain chances.
