Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Updated for the 12z aviation discussion.
Lifr ifr conditions to continue through much of the morning. Drier
air moving in from the west should aid in lifting CIGS toVFR by
the afternoon, but tempo MVFR conditions will be possible through
18z-19z. Will expect low CIGS to build back into the region toward
and after 00z. Sounding profiles favor br fg development in
addition to the lowering CIGS down to ifr MVFR. West winds this
morning will gradually become more southerly at around 5 kts.

short term (today through Friday)...
remnants of a weakening coastal trough will maintain isolated
showers across the gulf waters through the morning. Drier air will
move in from the west and gradually end rain chances through the
afternoon. This drier air should help lift clouds and may offer
some breaks for partly cloudy conditions in the afternoon. Warmer
temperatures are expected with highs in the low to mid 70s.
Slightly cooler conditions may exist along the coast where clouds
may take longer to lift.
For tonight, expect low level clouds to return with patchy to
areas of fog. Southerly flow will aide in warming overnight
temperatures into the mid to upper 50s. Should see sea fog across
the bays and nearshore waters where water temps are in the upper
50s while dewpoints rise into the low to mid 60s.
Onshore winds will strengthen and become breezy for most locations
Friday in response to deepening surface low pressure across the
southern high plains. This system will bring the next cold front
to the region just outside of the short term. The onshore flow
will return moisture and slight rain chances to the region. Warm
moderate southwest flow at h85 should help in warming temperatures
for Friday with highs in the mid to upper 70s. Despite this warm
flow typically creating a cap over the region, some weakening in
the cap along the sea breeze may allow for a few thunderstorms
weak westerly wind today will gradually shift out of the south by
tonight. Isolated showers will be possible today, mainly across
the gulf waters, with rain chances diminishing for tonight. Winds
will strengthen to more moderate levels Friday ahead of the next
cold front. Isolated showers will return to the region Friday.
Marine conditions will quickly deteriorate Saturday morning as a
strong cold front pushes offshore and over the middle texas
coastal waters. Showers and thunderstorms will be possible along
the front Saturday morning, with rain chances ending during the
late afternoon hours. Strong northwest winds, 25-30 knots, are
expected to pick up behind the front. Gusts near 40 knots will be
likely, especially over the offshore gulf waters. Small craft
advisories will be needed through late Sunday morning as winds
will continue to mix down. There will be a brief window Saturday|
afternoon where gale conditions will be likely. Seas will be quick
to respond behind the front with seas ranging from 8-10 feet
through Sunday morning.
As high pressures settles in late Sunday, marine conditions will
improve. Onshore flow will resume Monday morning. Southeasterly
flow will strengthen early next weekend in response to another
approaching cold front, resulting in another period of sca
Long term (Friday night through Thursday)...
Friday night kicks off a weekend of fairly active weather across
south texas. A strong mid-level trough will swing across the
state, sending a cold front through the region. Forcing along the
boundary, decent upper level divergence and moisture pooling ahead
of the front will lead to chances for showers and thunderstorms
Friday night into early Saturday morning. The greatest chances
will be across the northern coastal bend and victoria crossroads,
where instability (~800-100 j kg) and shear (40-50 knots) looks to
be the highest. Models are in fairly good agreement with the
front pushing offshore by 12z Saturday. Rain chances will quickly
taper off as drier air filters in behind the front.
We will start out the day on Saturday with temps in the upper 50s
to mid 60s. Temps will remain fairly steady throughout the day
behind the front. Northwest flow drier air behind the system will
allow for skies to clear Saturday afternoon. Clear skies will lead
to a chilly night across south texas as temps drop into the low
to mid 30s across the victoria crossroads and northern coastal
plains with temps in the low to mid 40s along the coast. Sunday
looks to be another cool day as temps will struggle to get out of
the 50s as high pressure settles in with temps dropping into the
mid 30s to mid 40s across the region once again Sunday night.
Elevated fire weather conditions will be possible for a brief period
Saturday afternoon across the western part of the CWA as relative
humidity values will drop into the mid 20s and winds stay elevated
across the region.
Onshore flow will resume early Monday morning, resulting in
warmer temps to kick off the work week. Another front will drop
into the region on Tuesday but does not look to be as strong as
the weekend cold front. Rain chances will also be limited as
moisture will be lacking ahead of the boundary.

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.
