1124 PM CST Sun Feb 18 2018

.DISCUSSION...
Water vapor imagery shows drier air working into the region and
this is reflected in forecast soundings and the lack of low level
moisture. Guidance shows a mixed bag with regard to ceiling
heights/visibility tonight but think the drier solutions may be on
to something. The pressure gradient is tight enough to support
moderate to strong winds and between the mixing from the winds and
slightly drier air, feel MVFR cigs will be most likely. Gusty
S-SE winds are expected on Monday as low pressure tracks across
the central plains. Sea fog at KGLS has dissipated and don`t think
it`ll be back overnight but could return again Monday evening. 43

&&

.MARINE...
The gradient has tightened significantly and sustained winds are
approaching 20 knots offshore so felt it was best to issue an SCA
for the offshore waters. Will carry a Caution statement elsewhere
but southerly flow is having trouble mixing to the surface over
the cooler nearshore waters. Fog has dissipated and dropped the
Dense FOg Advisory for the southern nearshore waters but continued
the Advisory off Galveston and Galveston Bay. Web cameras still
showing pockets of dense fog over the bay. 43

.PREV DISCUSSION... /ISSUED 848 PM CST Sun Feb 18 2018/

UPDATE...
Only minor changes made to ongoing forecast. Cloud cover and
elevated southerly winds in response to a surface low over the
High Plains will result in overnight low temperatures only falling
into the lower to mid 60s. May see a few isolated showers skirt
the Brazos Valley before sunrise as an upper level disturbance
located over Chihuahua on SPC Mesoanalysis lifts northeast
overnight.

National Weather Service Houston/Galveston TX
900 PM CST Sat Feb 17 2018

.UPDATE...
The main update with the forecast tonight is to account for a
farther south progression of a cold front than previously
advertised. The KHGX radar shows this boundary stretching from
Vanderbilt to Bonney to Texas City and with the KHGX VAD wind
profiler showing very light winds above the surface doing little
to inhibit the southward movement, expect density differences to
drive this boundary off the coast within the next 2-3 hours. As
this front cleared the NWS Houston office, the temperature dropped
7 degrees within 30 minutes. Given these short-term trends, have
lowered low temperatures a few degrees into the upper 40s to near
60. A brief northerly wind shift associated with this boundary
moving off the coast may result in a brief respite in sea fog
(detailed in the marine section below) before winds veer to the
east sometime in the 3-6 AM timeframe.

SPC mesoanalysis shows the 925 MB front located farther north,
roughly north of Interstate 10, and convergence along this feature
may produce isolated to scattered showers through the overnight
hours north of a Columbus to Liberty line. Patchy radiation fog
may also be possible as dew point depressions decrease overnight
through mid morning, with best chances west of a Madisonville to
Katy to San Luis Pass line.

Huffman

&&

.MARINE...
A weak boundary continues to move toward the coast. Models are
not in great agreement but the latest HRRR shows the boundary
making it into the coastal waters before becoming diffuse later
tonight. North winds will develop in the wake of the front and
slightly drier air will likely make it into the waters. The drier
air will help erode the fog and the north winds should push any
remaining fog away from the coast. There should be some brief
improvement in visibility between 04-08z. East winds will develop
after midnight and become SE on Sunday. Fog is expected to
redevelop between 08-10z and persist intermittently through Sunday
morning. Onshore winds will strengthen Sunday afternoon as low
pressure over eastern Wyoming deepens. The low will push east on
Monday/Tuesday and drag a cold front into the state. The front
will probably stall and onshore winds will persist into Wednesday.
Periods of sea fog will likely hang around during the first half
of next as warm and moist air continues to flow over the cooler
shelf waters. The long S-SE fetch will bring slightly warmer water
toward the Upper Texas Coast and this may mitigate the threat for
dense sea fog early next week. 43

&&

.PREV DISCUSSION... /ISSUED 556 PM CST Sat Feb 17 2018/

AVIATION...
A weak front extended from about Liberty to downtown Houston and
then along the I-69 corridor to about Edna. Showers were beginning
to develop along this feature. Short term guidance shows the
boundary remaining nearly stationary and gradually becoming
diffuse. Low ceilings expected to develop areawide as deep mstr
builds beneath a capping inversion. LIFR/IFR cigs expected late
tonight into Sunday morning with a gradual improvement to MVFR by
afternoon. Sea fog will be an issue along the coast and visibility
will fall below a mile at times at KGLS and probably KLBX. 43

.UPDATE...
It looks like the front has finally stalled out between IAH and
Hobby with a few showers still ongoing along it. Sea fog has
already begun to roll into the coastal zones this evening, but
the front will limit its inland progression. For areas south of
the front, fog will likely settle in tonight and remain in place
until late morning or midday Saturday. 11

&&

.PREV DISCUSSION... /ISSUED 604 PM CST Fri Feb 16 2018/

AVIATION...
A cold front evident on TIAH stretches from IAH to just north of
SGR this afternoon. Expect this boundary to continue translating
south towards HOU over the next 1-2 hours, resulting in a light
northerly wind shift. Weak convergence in the vicinity of the
front has been enough to produce a few light rain showers across
the Houston metro and have inserted a VCSH mention in for HOU and
SGR through early evening. Strengthening southwesterly flow 925
MB this evening may result in this frontal boundary stalling near
HOU and possibly lifting north towards IAH during the overnight
hours. Expect winds in the vicinity of the front to remain light
and variable overnight with terminals south of the frontal
boundary experiencing LIFR to IFR conditions as low ceilings and
fog develop.

Webcams show sea fog just beginning to enter the lower Galveston
Bay area and have delayed onset of lowered visibilities for GLS as
a result. As light southerly winds along the coast back ahead of
the front this evening, expect sea fog to overtake the terminal
with anywhere from VLIFR to IFR visibilities persisting through
midday.

Mixing south of the stalled boundary on Saturday should allow for
ceilings to lift to MVFR and scatter to VFR by the afternoon. A
secondary cold front entering the region on Saturday afternoon
will result in the development of isolated SHRA near CLL as it
begins to approach the terminals after 21Z.

Huffman

PREV DISCUSSION... /ISSUED 348 PM CST Fri Feb 16 2018/

DISCUSSION...
Weak front is slowly moving through the region. It should
gradually be losing support for a continued southward push this
evening and guidance continues to show it stalling somewhere
between I-10 and the coast overnight. It`ll probably meander
between Highway 59 and the beaches through Saturday night.
Although there`s not a lot of forcing, think there`s probably
enough llvl saturation and isentropic lift to maintain lowish POPs
in the fcst. Areas of dense sea fog will persist south of the
boundary. As lee side pressures fall, look for the stationary
front to head back north on Sunday.

The broad upper ridge that has been situated across the Gulf Coast
will make its way eastward and off the southeast U.S. coast early
next week as the next western trof digs southward. A more
pronounced southwest flow aloft will evolve going into midweek as
the eastern ridge expands northward and western trof southward.
Llvl s/se flow will increase thru the same time period as pressure
gradient tightens.

The next cold front will approach the area ~Wednesday next week.
With very little upper-level support for a continued southward
push, the front is likely to become stationary near the coast. This
type of pattern (blocking high to the east, trof to the west, sw
flow aloft transporting Pacific moisture and upper disturbances,
deep Gulf moisture in place, upper diffluence, and a stationary
boundary) has been known to be a prolific rain producer across the
area. We`re still a long way off--but just something we`ll be
keeping an eye on in the coming days. 47/22

MARINE...
A Dense Fog Advisory is currently in effect for the nearshore waters
this afternoon. Sea fog will likely roll back into the bays late
this afternoon into the evening hours, and a Dense Fog Advisory will
likely be needed once again for both Galveston and Matagorda Bay.
The development for sea fog will continue through the weekend, as
warm moist air remains situated over cooler shelf waters. Onshore
winds will pick up slightly Saturday morning in the offshore waters,
and the lingering frontal boundary will shifts northward through the
day Saturday. Surface high pressure will build into the area from
the north late Saturday into Sunday and winds will become easterly
by Sunday morning. Onshore flow will increase approaching SCEC
criteria Monday into Tuesday as a southeasterly fetch sets up across
the Gulf of Mexico. This will bring added moisture to the region,
through mid-week. Wave heights will also increase to between 3 to 5
feet. The next frontal boundary is forecast to reach SE TX next
Wednesday. Latest global guidance is showing the front stalling
before reaching the coast, which could hinder the clearing of sea
fog from the coastal waters.

743 PM CST Thu Feb 15 2018

.UPDATE...
Onshore flow continues to drag in lower to mid 60 dewpoints across
57-59 degree water which combined with the setting of the sun has
led to the rapid onset and slow spread inland of dense sea fog.
Visibility at PSX/GLS bouncing around between 1/4 and 1 mile at
this time. Have issued a Dense Fog Advisory for the coastal
counties. This will need expanding but some questions remain about
how far inland the dense fog will develop...fog will develop
across most if not all of the CWA but the dense fog will be the
question. Todays deeper mixing and starting off with the larger
T/Td spreads as well as deeper stronger south-southwesterly flow
and few low clouds in the Gulf all lead to mixed signals.
Preliminary thinking is that dense fog could reach to the I-10
corridor around 3 am. Anticipating the expansion of the dense fog
advisory but not until around 10 or 11 pm when latest guidance is
available and observational trends give greater confidence. 45

&&

.PREV DISCUSSION... /ISSUED 630 PM CST Thu Feb 15 2018/

AVIATION...
VFR conditions at the inland terminals gradually deteriorate to
IFR/LIFR near the coast where a persistent sea fog bank is
beginning to advect inland. Deeper mixing this afternoon than
yesterday and a southerly 30 knot low level jet overnight should
allow for VFR conditions to persist inland through the evening
hours (roughly 06Z) then deteriorate to IFR or LIFR after 06Z as
the weakening jet allows for lower ceilings and visibilities to
develop inland. UTS and CLL may only see a brief window for these
lowered ceilings after 10-12Z with all terminals except GLS
improving to MVFR by mid to late morning. Sea fog lingering along
the coast may mean IFR/LIFR conditions persist into the mid-
afternoon hours.

Evening surface analysis shows a cold front moving into the
Southern Plains out of Kansas and expect this boundary to reach
CLL, UTS, CXO, and possibly IAH during the afternoon hours.
Southerly winds 10-15 knots this evening ahead of this front are
expected to decrease 5-7 knots overnight and veer to the southwest
by midday. After frontal passage, expect north to northwest winds
5-7 knots and MVFR ceilings as low level moisture remains trapped
beneath the post-frontal inversion.

Huffman

PREV DISCUSSION... /ISSUED 329 PM CST Thu Feb 15 2018/

DISCUSSION...
Despite persistent onshore winds the past couple days, the lack
of a significant boundary and strong mid level ridging centered offshore
has limited precip. What it has allowed for is continued sea fog.
And that probably won`t change until at least Saturday night &
quite possibly longer.

A weak front will make its way into southeast Texas Friday then
probably stall around the Highway 59 corridor as it begins to lose
its upper support. This boundary will likely meander between
Highway 59 and near, or just off, the coast thru Saturday
evening. Look for fairly good chances of rain across northern
parts of the area. Closer to the coast (& proximity of the upper
ridge) there won`t be as much forcing so chances diminish as one
goes south. Should this front not make it off the coast, the
already prolonged period of sea fog will continue well into next
week.

The stalled front will move back north as a warm front on Sunday
as lee side pressures fall. Another stretch of warm and humid wx
will then persist into the middle of next week. Rain chances
should increase going into midweek as a southwest flow aloft
becomes more prominent and the next front makes its way into the
region. 47

MARINE...
Periods of sea fog (some dense) are expected to persist through the
rest of the week and likely into the weekend as the general weather
pattern stays in place. Light/moderate onshore winds will help keep
the warm airmass in place over the cooler nearshore waters.  A weak
cold front is expected to move into southeast Texas on late Fri and
then stall near coast Sat. Strengthening onshore winds and building
seas can be expected late Sun when the frontal boundary washes out.

.AVIATION...
The Ft. Hood VAD wind profiler is showing a 35-40 knot low level
jet has set up across Central Texas this evening and associated
mixing will likely limit fog development at the CLL and UTS
terminals tonight as southerly winds remain elevated in the 8-10
knot range. The main update to the 06Z TAF was to reflect these
trends. With the jet being weaker closer towards the Houston
terminals, still expect LIFR to VLIFR ceilings and visibilities
to develop overnight and persist through mid-morning before
lifting to MVFR. MVFR to VFR conditions are expected during the
afternoon as heating and southerly winds in the 10-15 knot range
allow for ceilings to lift with breaks in the clouds allowing for
stronger gusts in the 20 knot range. Another round of MVFR to IFR
stratus appears possible Thursday night.

Another night fog across the region. Dense fog already in place
over the coastal counties and starting to creep into the next
tier. Guidance is fairly consistent with winds relaxing slightly
south of a Columbus to Conroe to Crockett line and given the
propensity of fog will expand the dense fog advisory further
northward.

Some light drizzle/rain possible after midnight mainly across the
north in slightly closer proximity to the low level jet in this
extremely warm and moist airmass. Also increased overnight low
temperature a few degrees at most sites. Looks like temps may be
near bottoming out along the coast already. Dewpoints in the mid
