GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 425 Am Cdt Mon Oct 14 2019
Synopsis for high island to matagorda ship channel out 60 nm.. Generally light onshore winds will prevail today but winds and seas could be higher in and near scattered Thunderstorms associated with an inland moving warm front. This south and southeast flow will be strengthening a bit by Tuesday in response to the next storm system deepening over the rockies. The cold front associated with this system is expected to move off the coast Wednesday morning with caution flags possible over the coastal waters late Wednesday afternoon into early Thursday.

area forecast discussion
national weather service houston galveston tx
423 am cdt Mon oct 14 2019

Short term [through tonight]
Surface analysis shows coastal trof warm front right along the
coast early this morning. Further aloft, a continued messy pacific
flow remains in place. GOES pw product depicts 2.2-2.3" pw's in
place across parts of the region. Showers and tstms should
continue increasing in areal coverage closer to the coast this
morning where convergence along the trof warm frontal boundary
exists. Expect this feature to slowly edge inland today and, along
with weak impulses aloft, allow for precip to expand inland thru
the day. Earlier href members were a bit more bullish on areal
coverage today compared to some the of latest runs for whatever
reason. Gfs, ecmwf, nam12, nbm, icon & cmc all show more
widespread activity similar to what's in the ongoing fcst and
don't plan on changing that much.

Instability is fairly unremarkable, but still can't rule out a few
stronger cells... Especially if they can become rooted closer to
the sfc. Also need to keep an eye for some very isolated spinners
near the warm front. Otherwise, considering the deep moisture in
place... Brief localized heavy downpours should be the primary wx
issue.

Precip should taper off from south-to-north later in the day and
this evening as the moisture axis and boundary pushes north.

Better chances of rain should primarily be situated just north of
our CWA overnight. 47

Long term [Tuesday through Monday]
Precip will likely expand back south into the northern half of se
tx during the day tue... Coinciding with daytime heating and where
the deeper west-east oriented moisture axis and favorable tracks
of upper disturbances should be at that time.

The next cold front will make its way into the region late tue
night and off the coast early Wed morning. A line of shra tstms
should accompany the front, with some lingering post-frontal rain
chances continuing across the southern half of the area and
offshore until the upper trof axis passes thru sometime late
thurs.

Breaks in the rain will be brief however. Onshore flow resumes
Friday and the gulf will open back up. Medium range guidance isn't
in the best agreement as to where the deepest moisture pooling in
the west gulf will eventually track over the weekend... Whether
into tx or further east... So confidence isn't particularly high
in regards to overall rain chances. Models are however fairly
close showing our next stronger cold front moving thru next
mon tue. 47

Marine
Even with generally light onshore winds today, we'll likely see some
elevated winds seas in and near the increasing showers thunderstorms
this morning with the warm front moving into SE tx. Activity will be
decreasing a bit by this afternoon... But with the S SE winds picking
up (as a response to the next storm system deepening moving into the
southern plains), isolated WAA showers will be possible late tonight
and early tues morning. The next cold front associated with this sy-
stem is still forecast to move off the coast weds morning... With the
possibility of scec conditions over the near offshore waters by late
that afternoon (into thur). High pressure lingering over the eastern
u.S. Will help keep a mostly light moderate easterly flow across our
marine waters the rest of the week. 41

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.
