GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 841 Pm Cst Tue Jan 23 2018
Synopsis for high island to matagorda ship channel out 60 nm.. Despite high pressure located over eastern texas, a pressure gradient with lower pressures in the carribean is tight enough to result in more moderate northeasterlies offshore routinely flirting with caution thresholds, while lighter winds exist over the bays and coastal waters. This trend should continue early this week. Onshore winds by Thursday will pull in a warmer and more humid air across cooler shelf waters. This will increase the potential for sea fog Friday and Saturday.

Aviation
Vfr throughout, with scattered to broken cirrus present at 25k
feet. Light and generally northerly winds early will veer towards
northeasterly, and modestly pick up in speed closer to the coast
for the late morning and afternoon. Once the Sun is down, would
expect those winds to come back down some, but remain
northeasterly.

near term [through tonight]...

it really does not get much more quiet around here weather wise
than tonight. High pressure over texas will allow for light calm
winds. High clouds over the area will hinder some radiational
cooling but the airmass is so dry it may not matter much
(dewpoints in the 20s that suck the moisture out of you... Air you
do not wear). Overall forecast looks on track with only some
minor adjustments for ongoing trends.

vfr throughout, with main focus of the forecast being a slow
veering of generally light winds to northeasterly. Also, a band
of high cirrus is streaming across the area with some pacific
moisture, but doesn't look to be an issue below 25k feet.

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.
