Area Forecast Discussion
National Weather Service Houston/Galveston TX
924 PM CDT Mon Sep 4 2017

.DISCUSSION...
Surface high pressure was ridging into Southeast Texas this
evening. Isolated showers were moving around the ridge over the
offshore waters in the Gulf. Since sunset the showers have
pretty much dissipated; although, a few still were forming about
60 nm offshore of Matagorda. The 01Z run of the HRRR shows the
potential for isolated shower development off of the coast
through the remainder of tonight.

.PREV DISCUSSION... /ISSUED 630 PM CDT Mon Sep 4 2017/

AVIATION...
Generally light south to southeast winds are expected for the
remainder of the evening. Some patchy IFR to MVFR fog will likely
set in again tonight/early tomorrow morning before dissipating
after sunrise, very similar to what has been occuring the past
few mornings. A stray shower or two may be possible along the
seabreeze tomorrow afternoon. Otherwise, VFR conditions are
expected throughout the taf period.

PREV DISCUSSION... /ISSUED 346 PM CDT Mon Sep 4 2017/

DISCUSSION...
Moisture from a disorganized low in the Bay of Campeche is moving
north into the upper Gulf Coast with isolated showers now being
seen on radar approaching Matagorda. Rain chances will increase
along the coast and nearshore waters through tomorrow morning as
this moisture continues northward though convection should remain
isolated to widely scattered. The main threat will be isolated
cells producing gusty winds affecting marine interests.

A cold front currently entering the Texas Panhandle will move
south over the next 24 hours and enter our northern CWA around
midnight tomorrow night. Lift along the front is forecast to
weaken as the front moves south and so a solid line of convection
in North Texas is expected to develop gaps as it enters southeast
Texas. Showers with moderate rainfall rates will be moving at a
decent pace so QPF amounts should generally be less than a quarter
of an inch. A surface high building south behind the front will
advect cooler and drier air with dewpoints dropping into the 50s
and lows in the 60s Thursday morning. The high will remain in
place and slowly weaken so a gradual warming trend is expected
Friday into the weekend.

Hennig

MARINE...
Light onshore winds and low seas will continue through Tuesday,
before increasing and becoming offshore Wednesday morning as a cold
front clears the upper Texas coast. Expect winds to increase into
the 15-20 knot range behind the front with stronger gusts; these
elevated winds will result in seas building into the 3-5 feet range
nearshore and 4-6 feet range offshore. Caution or advisory flags
will likely be needed at times Wednesday through Friday before
conditions begin improving over the weekend.

Huffman

TROPICAL...
An area of low pressure in the Bay of Campeche is currently being
monitored for potential tropical cyclone development over the next 5
days. Regardless of development, Wednesday`s cold front appears to
make enough southward progress to keep any potential system well
south of Southeast Texas as it pushes the area of low pressure into
Mexico.

Hurricane Irma also continues to churn east of the Leeward
Islands this afternoon and is forecast to intensify further as it
moves west to west-northwest towards Florida over the next several
days. Hurricane Irma`s track beyond that point becomes a little less
certain, but medium range deterministic guidance is in fairly good
agreement that Irma is lifted northward before entering the Gulf of
Mexico as an upper trough reaches the East Coast. Changes in the
depth or trajectory of this trough would influence the ultimate
track of Irma. Additional radiosonde observations will be taken
across a few CONUS sites over the next few days to diagnose the
upper air pattern better. As this data is incorporated to later
model guidance, expect confidence in Irma`s forecast to increase.
Regardless, impacts are not expected in Southeast Texas from Irma
at this time but Irma`s forecast should still continue to be
monitored over the next few days.
