Area Forecast Discussion...UPDATED
National Weather Service BROWNSVILLE TX
746 AM CST Thu Nov 17 2016

.DISCUSSION...Have cancelled the Dense Fog Advisory for Jim Hogg
and Brooks counties. Observations indicate that the dense fog has
dissipated and visibilities have improved.

&&

.PREV DISCUSSION... /issued 543 AM CST Thu Nov 17 2016/

DISCUSSION...Posted a Dense Fog Advisory for Jim Hogg and Brooks
Counties per observations within those areas. The Advisory will be
in effect until 8 AM CST this morning.

AVIATION...Surface winds have remained strong enough overnight to
prevent the formation of fog at the aerodromes. VFR will prevail
today as surface winds become moderate with frequent stronger
gusts. MVFR is possible tonight as low stratus develops while
winds remain moderate.

PREV DISCUSSION... /issued 326 AM CST Thu Nov 17 2016/

SHORT TERM (Now through Friday): The most recent KBRO upper air
sounding indicated a precipitable water value of only .63 inches.
Although the atmosphere will moisten today, 500 mb high pressure
centered over the central Gulf of Mexico will dominate the weather
within Deep South Texas and the Rio Grande Valley, with continued
dry weather. Based on observed high temperatures from Wednesday,
inherited high temperatures were raised several degrees. Tonight,
the atmosphere will be sufficiently moist to produce isolated
streamer showers over the Lower Texas coastal waters. An improved
opportunity for precipitation, featuring isolated to scattered
showers and thunderstorms, will occur over the entire BRO CWFA as a
cold front approaches from the northwest and passes through at least
half of the region by the end of the forecast period.

LONG TERM (Friday night through Wednesday): The main forecast
challenge remains a cold front forecast to arrive in the first
period of the long term, i.e. Friday night. North winds will start
over the ranchlands Friday afternoon, increasing and advancing
through early evening. Midnight at Brownsville is still a reasonable
forecast right now. The shallow cold air wedge and lack of upper
forcing will limit convection, with rather quick stabilization post
front Saturday morning. Any weather will be pretty much over by dawn
except for perhaps for a few lingering showers over the lwr valley.
Low temps will drop into the 50s CWA wide. Strong high pressure and
drier air will move in rapidly behind the front, with clearing
skies through the day. Still, high temperatures will be mainly in
the 60s Saturday. Mostly clear skies and high pressure settling
over the area will result in a cool Saturday night. Low
temperatures will be in the 40s for most areas, except for the
immediate coast, which will remain in the 50s.

A warming trend will ensue on Sunday, with northeast winds starting
to veer as high pressure begins to slide to the east. Look for high
temperatures near 70 on Sunday and low temperatures in the 50s Sun
night. High temperatures will be near 80 on Monday as the warming
trend continue, with winds again southeast. The next plains low
pressure system will help strengthen southeast winds on Tuesday,
with a weak cold front pushing into Central and South Texas. High
pressure will remain dominant over the Gulf, supporting a southeast
flow on Wednesday, and with the Southwest Gulf becoming more active
by then, marine and coastal rain chances will be reintroduced for
the middle and latter part of next week.

MARINE:
Now through Friday...Buoy 42020 reported south winds around 16
knots gusting to around 19 knots with seas slightly under 2.5 feet
with a period of 4 seconds at 02 CST/08 UTC. High pressure
centered over the southeast United States will interact with a low
pressure system and associated cold front moving through the
Central Plains today and tonight. Strong winds and rough seas are
likely along the Lower Texas Coast, with Small Craft Exercise
Caution likely and Small Craft Advisory possible. A slight
improvement in winds and seas, below Caution or Advisory criteria,
is anticipated on Friday as the cold front approaches and weakens
the pressure gradient.

Friday night through Monday: Relaxed light winds will prevail
Friday evening ahead of a cold front, though seas offshore may be
4 to 6 feet and in SCEC territory. North northeast winds will
increase between 9 pm and midnight with the arrival of a cold
front. Small craft advisory conditions will be likely for all
marine zones, with gale force gusts possible over the Gulf waters
through Saturday mrng. Confidence is still borderline for gales
so not inclined to issue a watch this go around. Wave heights will
build to between 8 and 10 ft offshore by Sat aftn. Showers and
thunderstorms will be possible with the front Friday night, but
the duration will be relatively brief as the front will move
quickly through with limited dynamics. Conditions will improve Sat
aftn and after as high pressure spreads over the area. Winds
should be below 20 kts by midnight Saturday while high seas will
persist until Sunday morning. Conditions will continue to improve
Sun and Monday, with winds veering to southeast Sunday night to
Monday. Southeast winds will increase late Mon as the next plains
low pressure system interacts with retreating high pressure over
the Gulf.
