GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 959 Pm Cdt Sun Mar 24 2019
Synopsis for high island to matagorda ship channel out 60 nm.. Moderate onshore flow will persist through Monday afternoon. Areas of sea fog are looking increasingly probable tonight, potentially through early Tuesday morning. A cold front will move through the region late Monday into early Tuesday morning, helping to improve any lowered visibilities due to sea fog. Increased northeast winds and building seas are expected in the wake of the front Tuesday afternoon. High pressure quickly moves east and onshore winds should resume Wednesday and persist through the remainder of the work week.

Aviation
Lowering ceilings visibilities have not materialized as fast as expected
this evening, but goes-16 night fog and surface observations are starting
to show signs of this happening. Still think we should see MVFR ifr
ceilings and or visibilities before sunrise with slow improvement expected
in the morning. Rest of thinking has not changed. Winds will become
w ahead of a cold front then NW to N and increase behind the boundary
as it moves across the area. Current timing of the front looks like
mid late morning cll and uts, mid late afternoon iah and hou and sgr,
and after 26 00z at gls. Could see some shra (maybe an isolated tsra?)
along and ahead of the front. Gradually becomingVFR after the front
moves on through. 42

discussion...

sorry for a very brief discussion... But kind of time crunched at
the moment. Thankfully not a whole lot to talk about wx-wise.

May see some sea fog develop near the coast overnight as warmer,
moisture rich air makes its way over slightly cooler waters.

Otherwise, continued warm with spotty shra at best.

Flow generally veers to the SW during the day tomorrow ahead of a
weak cool front making its way into the area. Should provide for a
warm day. There will be a chance of shra and isolated tsra ahead
of the boundary, though overall forcing convergence deep moisture
isn't anything impressive. Probably just a very bkn thin band of
precip ahead of the boundary.

Nice spring wx in the wake of front. Winds swing back to SE by
midweek as high pres moves off to the east with a gradual return
of gulf moisture back to the region during the 2nd half of the
week.

Elongated trof stretching from the great lakes into the desert
southwest will put us back into a messy SW flow aloft and
increasing rain changes as we head into next weekend. 47
marine...

southeasterly winds between 10 to 15 knots this evening will
eventually become more southerly between 5 to 10 knots overnight.

Patchy to areas of sea fog will be possible over the nearshore
waters beginning early Monday morning and potentially last until
Tuesday morning until the passage of a cold front. The cold front
should push through the gulf waters by Tuesday morning, helping to
improve diminished visibilities due to sea fog as drier air ushers
in. At this time, scec conditions look likely behind the passage of
this front, with winds out of the northeast and seas forecast to
build to between 2 to 4 feet. High pressure will fill in behind this
boundary and as a result winds will turn out of the east late
Tuesday afternoon into Wednesday. Easterly winds will persist
through Thursday morning as winds turn back onshore out of the
southeast. Caution criteria may be needed for the gulf waters
towards the later half of the week as easterly flow turns back
onshore. Tides are forecast to run near normal through the remainder
of the week. Hathaway

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.
