Synopsis for high island to matagorda ship channel out 60 nm.. Look for light winds to become onshore late this afternoon as high pressure drifts east. Southerly winds will increase Saturday into Sunday ahead of the next cold front. The front should push off the coast early Monday with winds and seas increasing from the northeast.

Forecast looks good, and no significant changes were needed on the
morning update. High temperatures this afternoon in the mid to
upper 60s for most spots still looks to be on track. Enjoy! 42

aviation [12z TAF issuance]...

quiet TAF period ahead, withVFR conditions throughout and winds
around or below 5 knots. Only real change to track will be shift
in wind direction from W SW to S SE as high pressure exits to the
east. Likely little impact given the light winds, but wanted to
highlight it as the forecast issue of the day.

prev discussion issued 432 am cst Fri nov 16 2018 ...

short term [today through Saturday night]...

despite mid level clouds moving across the area, temperatures
have dropped across the area into the 30s 40s. Latest IR and
nighttime microphysics rgb imagery from GOES 16 does a good job of
picking up on the mid level clouds moving across the area.

Interestingly enough, the GOES 16 6.95 micron water vapor channel
shows this short wave trough the best out of the 3 water vapor
channels which further helps determine cloud heights. This system
is on its way east with clearing skies behind it. Otherwise upper
level analysis and water vapor imagery show fairly flat flow
across the southern u.S. With ridging off the pacific coast.

At the surface, high pressure has pushed east over the northern
gulf coast with light southerly winds over SE texas. The
temperature forecast will be the main forecast problem the next
couple of days. Winds at 925-850mb turn south to southwest today
and tomorrow. This should help temperatures recover into the upper
60s to low 70s for high temperatures each day. Moisture from the
gulf should also return with dewpoints climbing back into the 50s,
perhaps the low 60s just along the coast.

Long term [Sunday through Friday]...

the long term forecast features a myriad of forecast problems.

Let's start with Sunday. Jet stream pattern resembles that of an
omega block out west typical of an EL nino type pattern with a
ridge over the pacific coast, troughing over the central eastern
u.S. And zonal flow undercutting the pattern across mexico and
southern gulf coast states. What this does is allow for a short
wave trough now over the pacific NW to drop into the plains and
shear out as it does so on Sunday. This also allows a cold front
to push south into the area during the day Sunday. The 850mb front
does not come anywhere close to the area which means we have
another shallow cold airmass to ooze into the area wreaking havoc
on the temperature forecast. Basically the front will likely push
through college station in the morning much like the NAM suggests
with temps in the 50s behind it. The front slows down with day
time heating ahead of it and may take its merry old time to push
into houston during the afternoon. Ahead of the front high
temperatures could very well be back into the low 70s. This leaves
a good 20 degree temperature gradient across the area and a
sharper gradient that we can forecast 3 days out. So this part of
the forecast will likely change depending upon the speed of the
front and how well forecast models handle the cold airmass. In
this forecaster's experience, the models do a very poor job
handling these airmasses. There will be some rain chances, mainly
showers with the front, but the higher rain chances will likely
occur after the front pushes through and off the coast.

Monday through the end of the week - this is when the real fun
begins in the forecast. Basically we will hold onto the southern
branch of the jet over much of texas through the week. This means
we have to be careful to watch for short wave troughs coming out
of mexico. It looks like on shortwave comes across Monday Tuesday
time frame out of the southern rockies. A stronger wave comes
across Wednesday into Thursday for the thanksgiving holiday.

Forecast will hold onto some higher rain chances for each of these
troughs with drier conditions for the end of the week. In the
case of both of these storm systems, a coastal trough low should
form along the front in the NW gulf and move east across the
northern gulf. Models do not bring any of these surface lows north
with the warm sector developing inland. This should keep any
severe weather or heavy rainfall threat to a minimum. That said,
there will still be strong warm advection and isentropic lift over
the front to support bands of rainfall and quite possibly
elevated convection. Models soundings for the nam GFS are not all
that impressive when it comes to elevated instability for Monday's
system but there are still some favorable lapse rates from
700-500mb and plenty of shear. GFS soundings show similar
conditions for the Wed thur time frame. Both the GFS and ecmwf
show pretty strong vorticity advection and large scale ascent with
each system, more so with the mid week system. Fortunately the
models continue to show the highest rainfall amounts well off the
coast in the gulf that the area should avoid the heavy rainfall
threat. That's not to say we will not get any rain in the area
because we are still looking at a good 1 to 3 inches of rain
across the area for the 5 day period next week. It just looks like
those isolated higher amounts will stay of the coast and not be a
problem for the area. Keep in mind this is still the extended
forecast and we've seen the second shortwave trough change in
timing for Wed thur quite a bit with the last day or two's worth
of model runs.

Overpeck
marine...

look for quiet weather, and light offshore flow to continue while a
high pressure center drifts by about 60 nm offshore. As it moves off
to the east, look for winds to become onshore tonight. Those winds
will gradually bring higher moisture air over the waters until a
cold front arrives later in the day Sunday. At this time sea fog is
not anticipated, but it will be worth keeping up how much the gulf
waters will warm into this weekend versus the increase moisture
content of the air above it.

Behind the front, look for gusty northeasterly winds and higher
seas. Scec conditions will be possible at times early next week.

The return of onshore flow will also mean the return of tides that
are near or slightly above astronomical tides.
