GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 331 Pm Cdt Fri Jun 23 2017
Synopsis for high island to matagorda ship channel out 60 nm.. Southerly winds are gradually slackening, and seas are following, but delayed a few hours. For this reason, though the small craft advisory has expired, small craft should continue to exercise caution into tonight. Winds and seas will continue to slowly diminish into the weekend, with periods of moderate onshore flow and elevated seas returning around midweek.

Discussion
A hot afternoon is well underway for southeast texas with 3 pm cdt
temperatures in the low to mid 90s inland and heat index values
ranging from 98 to 107. Visible satellite imagery shows a
scattered to broken stratocumulus deck developing around 4500 feet
and spreading south within an area of isentropic lift on the 310 k
surface. Rap guidance shows this area of lift gradually
translating east over the next few hours (likely as the remnants
of cindy pull farther away from the region), allowing at least
some of these clouds to translate towards the south and east with
it. For those areas lucky to get some shade from these clouds,
temperatures may quickly drop 2-3 degrees and provide some relief
from the heat. Otherwise, cannot rule out a stray shower along the
coast or across the far extreme eastern counties through the
remainder of the day but this would be the exception and not the
rule.

Not much cooling is expected overnight with lows only falling into
the mid 70s to low 80s, but rain chances will increase across the
region on Saturday and Sunday as southeast texas remains situated
in a relative upper level weakness between two ridges. Speed
convergence along the coast Saturday will result in scattered
morning showers, with the northern counties seeing a thunderstorm
complex along an approaching (weak) cold front also during the
morning hours. Regional radar mosaic already shows storms
beginning to develop along this cold front across portions of the
low rolling plains and along the red river, with additional
upscale growth into a thunderstorm complex expected through the
remainder of the afternoon and evening hours as the front pushes
south towards the region.

The cold front looks to make a run for the interstate 10 corridor
through the remainder of the morning hours Saturday, stalling
near or north of it as a sea breeze pushes inland during the late
morning and afternoon hours. Daytime heating and the collision of
both of these boundaries is expected to result in the development
of scattered to numerous showers and thunderstorms on Saturday,
with greatest coverage centering wherever the boundaries collide
(likely near interstate 10). Convection should wane with loss of
heating by Saturday evening. Another round of morning showers are
expected on Sunday, with scattered to numerous thunderstorms again
developing with daytime heating and likely focusing along
wherever the remnant frontal boundary (or outflow boundaries from
Saturday's convection) is. The front won't have much of an effect
on temperatures but increased clouds on Saturday and Sunday will
keep temperatures a few degrees cooler than today with highs in
the mid 80s to low 90s.

Similar to what the previous forecast noted, storm motions will
be very slow both days (around 5 knots Saturday, 10 knots Sunday)
and this, combined with precipitable water values 1.8-2 inches,
will result in the threat for locally heavy rainfall and the
potential for some localized flood issues as thunderstorms have
the potential to remain nearly stationary before collapsing. Sref
plumes show forecast rain totals generally in the 1-2 inch range
during this time, but would not be surprised to see some isolated
2-3 inch totals occur given the aforementioned environmental
conditions. Will also have to keep an eye on a gusty wind threat
as well on Saturday. Relative humidity progs show drier air
evident over the northwest gulf on afternoon water vapor imagery
working its way into the region from the south southwest. This
drier air would help enhance evaporational cooling, accelerating
downdrafts and creating the potential for gusty winds in stronger
convection on Saturday.

The region remains under this relative weakness in the upper flow
through the middle of the upcoming week, with mainly daytime
shower and thunderstorm chances inland through mid-week.

Expect these chances to gradually decrease early to mid next week
as 500 mb heights increase and atmospheric moisture content drops
a bit. These increasing mid-level heights and decreasing rain
chances will also result in gradually warming temperatures with
highs increasing to near or slightly above normal (low to mid 90s)
by the end of the next work week.

Marine
Winds are slowly diminishing today, and seas should also come
down with them on a bit of a delay. Though winds may not quite be
at the scec threshold, the lag in waves should justify keeping it
in place into tonight. Going into the weekend and early next week,
light to moderate flow is expected, generally onshore. An
approaching front may back winds slightly to more easterly from
Sunday, but will still be generally onshore. Some stronger winds
may be possible mid to late week.

Tides also remain elevated, and astronomical high tide at around
two feet at galveston are not aiding matters. Another chance at
coastal flooding in vulnerable areas around high tide early
tomorrow morning can't be ruled out. Will hold off on another
coastal flood advisory for now to gauge tidal behavior through low
tide and into the upswing towards high tide.

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.
