GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 413 Am Cdt Tue Oct 24 2017
Synopsis for high island to matagorda ship channel out 60 nm.. Strong offshore winds will develop behind a colf front pushing off the gulf coast this morning and persist into tonight. Winds will diminish on Wednesday and then become onshore by late Thursday as high pressure moves east of the area. Another cold front should arrive at the end of the week on Friday. Strong northerly winds behind the front will likely prompt small craft advisories.

Discussion
The autumn weather pattern will continue for the next several days
across southeast texas. Main issues include a cold front moving
across the area today and another cold front on Friday. Both
fronts will bring unseasonably cool weather conditions across all
of the forecast area.

Items of concern regarding today's cold front include breezy and
dry conditions following the frontal passage. These will elevate
fire weather conditions across the area (see the fire weather
section below for more details). Temperatures following the front
will fall into the 40s and 50s tonight and early Tuesday morning.

After another cool, dry, but not as breezy day on Wednesday,
onshore winds will begin to return gulf moisture on Thursday. The
second cold front will arrive Friday. There has been some
differences in model precipitation output. Current thinking is
that isentropic lift ahead of the front should aid in the
development of isolated to scattered showers with best chances
along the front and over the southeastern half of the forecast
area. The main impact from the front will be after the frontal
passage over the weekend. Early morning low temperatures will
likely fall into the mid and upper 30s over the far inland areas
Saturday and Sunday morning with the coldest morning likely Sunday
morning. As of now, lowest temperatures could be near 34 or 35
degrees over locations north of a line from burleson to huntsville
to cleveland. Could see some upper 30s as far south as liberty
county, northern harris county, and locations southwest of metro
houston along the inland portions of the coastal counties.

As the high pressure area moves northeast of the forecast area, a
warming trend is expected starting on Monday. This should be aided
by southwesterly winds at the surface Sunday night and onshore
winds by late Monday.

Winds should increase towards sunrise this morning as a cold front
pushes through the area. Winds are expected to reach advisory levels
over the gulf this morning. The advisory begins a few hours before
the threshold is forecast to be met to cover the period of scec-
level wind. The advisory carries through Wednesday morning - the 0-
20 nm zones may see a bit of a lull in the afternoon, but with the
expectation that winds will exceed the advisory threshold again
tonight. The advisory may need to be extended through Wednesday
morning.

Look for winds to diminish Wednesday as another high pressure center
moves across the region. As that high moves off to the east, onshore
flow should return on Thursday. The next front is expected to arrive
Friday, and looks strong enough to bring another period of strong,
gusty winds. This front may be stronger than the previous front with
the potential for wind gusts to gale force. Small craft advisories
may be needed Friday through Saturday.

Fire weather
A front will continue to push through the area this morning and
drier air behind it will re-enforce the already drier cooler airmass
in place. Rh levels should drop to around 20 to 25 percent this
afternoon. The area is fortunate to have generally wetter than
normal fuels due to recent rain. Outside of the 10 hour fuels, which
are more receptive to changes in rh, rain from Sunday morning will
help mitigate conditions. Due to the higher fuel moisture, we will
decide against going with a red flag warning. However, those with
more grassy fuels should be aware of the dry air and winds expected,
and understand that fire may spread more rapidly than they might
expect given the recent rain. Should rh drop lower than forecast or
winds become stronger, we will need to issue a red flag warning
today.

Low humidity will persist Wednesday and Thursday. Winds will be
lower on Wednesday as high pressure moves over across SE texas.

Winds increase Thursday ahead of the front and enough moisture will
return for some rain chances ahead of the next front on Friday.

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.
