Synopsis for the middle texas coastal waters.. Sustained gale force winds are expected across the bays and coastal waters through tonight into Friday in the wake of a strong cold front. Large seas will also build through Friday morning. Strong offshore flow and elevated seas will slowly subside Friday afternoon through late Saturday morning. A northeast flow will develop Sunday as high pressure moves east. Onshore flow will resume next week as a coastal trough begins to develop which will lead to low-end rain chances.

350 pm cst Thu dec 13 2018

Short term (tonight through Friday night)
Potent upper low continues to spin across northern tx, with very
strong west to northwest winds across inland portions of the cwa
this afternoon in the wake of a strong cold front. The strongest
winds are currently moving into the western CWA and expected to
continue spreading across S tx through the remainder of the
afternoon. Wind advisory conditions are expected to continue
overnight along the coast. Strong winds are expected to continue on
Friday then diminish late Friday afternoon into Fri evening.

Other than some mid upper level clouds wrapping around the upper low
and across the victoria crossroads tonight, most of S tx will be
clear to mostly clear through the short term. Much drier airmass,
mostly clear skies and diminishing winds Fri night will lead to
lower min temps with lows in the mid 30s to lower 40s and wind
chills in the 30s Fri night.

Long term (Saturday through Thursday)
High pressure will continue to build into the region as we head into
the weekend. Winds will stay elevated over the gulf waters through
Saturday morning as the pressure gradient gradually relaxes. The mid-
level ridge and associated high pressure will keep our weather quiet
through early next week. Much drier air will filter into the region
over the next couple of days, which will result in cooler nights
with lows dropping into the upper 30s to mid 40s Saturday night.

Winds will primarily be out of the north through the weekend and
will gradually swing back to the east southeast as the surface high
slides east early next week.

As onshore flow resumes early next week, moisture will increase
across the region, which will bring low-end rain chances back into
the forecast, primarily over the gulf waters. Rain chances continue
to pick up by mid week as a coastal trough begins to take shape
ahead of a passing mid-level system.

Marine
A moderate to strong southerly flow is expected tonight with
advisory conditions developing across the offshore waters. Winds are
expected to briefly lower Thu morning ahead of a strong cold front.

A very strong offshore flow is expected behind the front late thu
morning into early Thu afternoon. Winds are expected to increase to
gale force with gusts approaching storm force Thu afternoon evening.

Therefore, the gale watch has been upgraded to a gale warning.

Small craft advisory conditions are expected to continue through
early Saturday morning with winds gradually relaxing by mid morning.

Sca and scec conditions will return by mid week as moderate to
strong north winds return.

Fire weather
Winds are expected to decrease slightly overnight and humidity is
expected to increase ending red flag conditions tonight. However,
due to the expected strong winds and low rh values on fri, a fire
weather watch remains in effect for Fri across the brush country
and southern coastal bend. Fire weather conditions may be elevated
fri across the victoria crossroads.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
