6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis for the middle texas coastal waters.. Southerly winds may approach advisory levels across the nearshore and offshore waters tonight. Winds will weaken some Saturday ahead of a cold front. The cold front will move across the coastal waters Saturday evening, with strong offshore flow expected behind it. Small craft advisory conditions are expected Saturday night and Sunday. Some gusts to gale force will also be possible over the gulf waters. Generally weak onshore flow will develop Monday and Tuesday as the center of a surface high pressure system enters the southeastern united states. Isolated showers are anticipated Tuesday and Wednesday in response to an approaching upper level disturbance and an increase in moisture.

See .Aviation discussion for 00z tafs.

Couple of issues this package. First, the potential for fog and or
low ceilings. Looks like a good low level jet develops tonight but
shifts NE late. Still, it will be potent enough to likely preclude
dense fog, but not the lower clouds. Thus, am going with ifr
conditions (both CIGS and vsbys) at kvct and kali, with potential
for lifr CIGS at kali where moisture will really thin out.

Possible MVFR br CIGS at klrd between 09z and 13z but again the
moisture will begin to thin out (but the jet will be more to the
east too). No fog at kcrp (maybe ground fog) but possibly MVFR
cigs. Conditions goVFR all areas no later than 16z all locations
(last at kvct).

Now the front. Will have a gradual wind shift during the morning
going SW to W and then N mid to late afternoon with some gusts.

Approximate FROPA at klrd before 22z and kvct 20z with gusty
winds. Trickier at kcrp and kali, with the front delaying a bit
in the afternoon but winds should shift north before the end of
the terminal forecasts each location but did not include gusts
just yet. Could have a few showers along the boundary at kcrp.

short term (tonight through Saturday night)...

main feature of interest in the short term will be the strong cold
front on Saturday. Prior to the front, another mild night is
expected across south texas. Overnight lows will fall into the low
70s along the immediate coastal with 60s elsewhere. Similar to
last few night, some patchy fog will be possible, most likely
developing around 08z or 09z. Confidence is not high that dense
fog will develop and will not mention in the forecast.

On Saturday, an upper level trough will swing through the central
and southern plains. At the surface, a cold front will be moving
southward across the state during the day. The front should be
roughly north of the forecast area around 18z and near the coast
by 00z. Temps should be able to warm up nicely before the front
moves through. Highs in the mid 80s across the north to low 90s
across the far southern sections look reasonable. Rain chances
look pretty low as moisture is not overly impressive prior to
fropa. Will retain 10 pops with mention showers during the
afternoon along the immediate coast, but the slightly better
chances will occur over the gulf waters during the afternoon. Most
locations will remain dry.

Much cooler and drier air will arrive Saturday night into early
Sunday morning. Lows will fall into the mid 40s to lower 50s.


moderate onshore flow will continue tonight over the nearshore and
offshore gulf waters. Winds will generally be in the 15 to 20 knot
range, but a small craft advisory could become necessary if winds
are slightly higher. Strong northerly winds will pick up behind a
cold front Saturday night. Scas will be likely but some gusts to
gale force will be possible over the gulf waters.

Long term (Sunday through Thursday)...

strong northerly wind will relax over the waters through the day on
Sunday as high pressure settles in, and then will gradually return
out of the east-southeast Monday as the high slides east. CAA should
continue Sunday to keep temperatures in the 60s overall, however a
few locations may reach near 70 degrees, especially toward the
southern coastal bend. Chilly conditions will be felt come Sunday
night Monday morning as dry air aloft and partly cloudy skies should
lead to good radiational cooling. The shift in the wind on Monday
will lead to temperatures rising back into the 80s by Tuesday. Long
term models now have some agreement with a similar set up for next
week, but still disagree on minor things as positioning and moisture
return. Overall, an area of low pressure at the surface is expected
to develop across the texas panhandle late Monday early Tuesday and
dip southward with the next approaching mid level trough Tuesday
night. The surface low becomes more of a trough as it moves south,
with winds shifting more out of the east-northeast drawing moisture
into the western gulf and across the texas coast. This will return
rain chances for mid week next week. Surface high pressure will
slide in from the north and bring another frontal boundary through
on Wednesday night, ending rain chances yet allowing for strong
winds to again develop across the waters. Temperatures will cool
slightly behind this front but generally be in the upper 60s to
lower 70s.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at 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.
