GMZ200 312 Pm Cdt Fri Oct 18 2019
Synopsis for the middle texas coastal waters.. While no direct impacts are expected across the middle texas coast, tropical storm nestor continues to move northeast across the gulf of mexico. This will introduce longer period swell and higher swell heights to the gulf waters. Otherwise, weak to moderate onshore will continue through Saturday night, with an isolated shower or Thunderstorm possible Saturday night. Weak to moderate onshore flow is expected with isolated showers and Thunderstorms Sunday. A cold front will push offshore Monday afternoon with scattered showers and Thunderstorms likely. Small craft advisory conditions will be likely Monday evening and persist through Wednesday morning as moderate to occasionally strong northerly flow develops in the wake of the front. We look to dry back out by mid week ahead of our next approaching cold front.

Short term
Afd... Short term (tonight through Saturday night)
drier conditions will continue tonight with limited moisture over
the area. An upper level system will move to the north of the area
through Saturday but limited moisture will limit any precipitation.

Went ahead and introduced some very low pops across the victoria
crossroads and the coastal plains Saturday afternoon through
Saturday night as there is the possibility of an errant shower. Also
continued the mention of patchy fog Saturday morning across the
coastal bend coastal plains as the morning dewpoint depressions are
quite low and the winds will be light.

Extended the coastal flood advisory through Sunday morning as the
estof and p-etss continue to show tide levels near or over 2 ft msl
and increased swell from tropical storm nestor is reaching the
coast. With swell reaching 8 to 9 seconds also included a high rip
current risk for Saturday through Saturday night.

Long term (Sunday through Saturday)
Rain chances will increase on Sunday as moisture pools across the
coastal bend while a weak shortwave moves across the region. A
stacked low moving across the northern plains will send a cold front
south across the state. Moisture will continue to pool ahead of the
boundary with pwats reaching ~2". Instability will be on the rise as
the front sags south. Model soundings MLCAPE values around 1500 j kg
and dcape approaching 1000 j kg. Would expect scattered showers and
thunderstorms as the boundary moves through with brief heavy
rainfall and gusty winds. The exact time of the front still is not
that clear with the ECMWF continuing to be a bit faster. The main
suite of models are in agreement with the front pushing offshore
during the early afternoon hours.

Behind the front, drier air will filter into the region which will
reduce rain chances to the coastal waters. Temps mid week will be
rather pleasant with highs in the low to mid 80s and lows generally
in the upper 50s to mid 60s.

Rain chances creep back late in the work week as a weak coastal
trough pushes back north with chances mainly over the coastal bend
and victoria crossroads. Another cold front will push through on
Friday. Timing still varies quite a bit with the ECMWF being much
faster but a mid day frontal passage looks reasonable right now.

This one looks quite a bit stronger with high temps in the 70s on
Friday and lows in the 50s.

The coastal flooding threat looks to continue into next week as both
estofs and ptess output are showing tidal levels exceeding 2ft msl.

One thing to keep an eye on is the threat of needing a coastal flood
warning tides may approach 3ft msl.

Marine...

higher sea heights and longer period swells are likely in response
to tropical storm nestor. A high risk of rip currents are expected
Saturday morning through Sunday morning. A very isolated shower or
thunderstorm will be possible Saturday night. Weak to moderate
onshore flow is expected with isolated showers and thunderstorms
Sunday. A cold front will push offshore Monday afternoon with
scattered showers and thunderstorms likely. Small craft advisory
conditions will be likely Monday evening and persist through
Wednesday morning as moderate to occasionally strong northerly
flow develops in the wake of the front. We look to dry back out by
mid week ahead of our next approaching cold front.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
