GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 343 Am Cdt Sat Jun 24 2017
Synopsis for high island to matagorda ship channel out 60 nm.. Winds and seas will gradually continue to diminish throughout the day today. Some scattered showers and Thunderstorms are possible across the waters through the next several days. A front approaches this weekend but should not quite make it off the coast. Onshore winds will ramp up around mid week as we become sandwiched between surface high pressure over the se conus and a developing surface cyclone over the lee of the rockies.

Aviation
Complicated and messy forecast today. Patchy fog and some low cigs
have settled around SE texas this morning. At the same time, a
broken line of thunderstorms is pushing southwestward through the
northern TAF sites right now while scattered showers and storms
continue to develop near the coast and push northward into the
southern half of the TAF sites. Model consensus is generally that
periods of showers and thunderstorms will be ongoing for today and
into this evening, but overall timing trends are very hard to pin
down. Other than the initial convection happening right now, the
tafs have vcts wording pretty much all day and amendments will
likely be needed to better pin down the timing as things progress.

Vis and CIGS should gradually improve toVFR other than right
inside thunderstorms this afternoon with some possible MVFR cigs
and patchy fog developing again overnight tonight. 11

discussion...

precip along a long lived ssw moving outflow has combined with
another line of shra tstms moving swd across north texas. This
line is currently moving into southeast texas ahead of
schedule forecast. Assuming it maintains about the same motion,
it should be situated from roughly brenham to houston to winnie by
around 8am. Speed convergence along the coast is contributing to
additional (and increasing) precip development along the coast.

The threat of localized heavy rain will occur should this continue
to fill in and collide merge with the incoming precip from the
north later this morning. We've included the mention of heavy
rain in the grids for areas generally along south of a bellville
liberty line this morning.

Not a whole lot of confidence as to what the remainder of the day
has in store. One would think we'd have a decent break in the
early to mid afternoon hours in the wake of this mornings
activity. But with 2-3.3" pw's in place, along with low convective
temperatures, it won't take much heating to get additional
activity to develop. Have 50% pops in as placeholders for the
afternoon, which can be adjusted either way as trends are
established.

Southeast texas will remain in a general weakness aloft for a good
portion of the week. Available moisture will be highest, and
convective temps lowest, areawide between now and Tuesday. Slow
storm motions are forecast, at least on the synoptic scale, as
well so we'll need to continue to keep an eye on the localized
heavy rain potential. Timing of precip will be difficult, and much
will probably occur on a mesoscale microscale level not modeled
well further in time. So, like this afternoon, a lot of the pops
and timing are broad brushed and will be refined with near term
trends.

Gradually lowering moisture levels, especially inland, are
expected during the second half of the week. So we'd generally
expect warmer conditions and less precip coverage then. Medium
range solutions do try to gradually build the eastern ridge back
overhead next weekend. 47
marine...

a scec is in effect through 9 am this morning as winds will be at
least gusting to over 15kt through around mid morning. Winds and
seas will continue to diminish over the weekend before ramping up
again beginning mid week as the gradient tightens in response to a
developing surface cyclone over the lee side of the rockies.

Tides remain slightly elevated this morning and are running about
1.5 feet or so above normal. A beach hazards statement is in effect
through noon today as these tide levels and wave run up will likely
cause some water to wash over hwy 87 on bolivar around high tide
this morning. These conditions will also likely cause strong rip
currents and longshore currents along gulf-facing beaches today.

With winds and seas gradually diminishing, tide levels should
improve heading into this weekend. 11

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.
