.SHORT TERM...
(Today through Tuesday Night)
Issued at 321 AM CST Mon Dec 30 2024

A fairly progressive weather pattern is progged to continue through
the short-term.

Widespread fog, dense at times, will continue across much of SE TX
through mid to late morning. Conditions will be improving in large
part to the increasing S/SW winds late this morning. This tighten-
ing gradient (in response to the deepening surface low moving over
the Southern Plains this afternoon) will also help to produce well
above normal high temperatures today. Max readings should run from
the mid to upper 70s across the Piney Woods...to around 80 for the
rest of the CWA.

With winds decreasing by this evening, cannot rule out a return of
some patchy for tonight. However, these lower visibilities will be
short-lived to some extent with the passage of the next cold front
during the overnight hours. Current timing has this line at/around
our northern CWA around midnight...then pushing off the coast just
before sunrise Tues morning. High pressure building south from the
Plains will make for a dry/cool and quiet last day of the year. As
for temperatures, lows tonight will range from the mid 40s to upp-
er 50s. Highs tomorrow should be in the 60s, with lows tomorrow in
the mid to upper 30s north and the lower to mid 40s central/coast.

.LONG TERM...
(Wednesday through Sunday)
Issued at 321 AM CST Mon Dec 30 2024

Mostly clear to partly cloudy skies and seasonable temperatures
behind Tuesday`s front will yield to increasing cloudiness
Thursday into the weekend in association to a developing coastal
trough off the mid/lower Tx coast. Isolated to scattered rain
chances will return to the forecast Thurs-Fri, mainly for
locations south of I-10.

A warm front is forecast to move inland Saturday as the next wx
system takes shape. A low pressure area should develop across the
TX/OK Panhandles and draw Gulf moisture back into the region in
addition to and bringing an upward tick to the temperatures. As
the low tracks eastward into Arkansas, its associated cold front
should move into, and through, Southeast Texas Sunday night.
Showers, and dependent on the atmospheric profile at the time,
maybe some thunderstorms will probably accompany the front.

It`s beyond the scope of this forecast, but next week is looking
to be on the cool-cold side with some Canadian air eventually
sinking into the region. 47

.AVIATION...
(18Z TAF Issuance)
Issued at 1122 AM CST Mon Dec 30 2024

Fog and low ceilings are continuing to burn off which will leave
us with SKC area-wide by the top of the hour. Southwesterly winds
around 10-15 kt and occasional gusts between 20-25 kt will prevail
throughout the afternoon till sunset. Winds trend towards light
and variable after 00Z, which opens up the potential for another
round of patchy fog amd low ceilings ahead of an approaching
frontal boundary. The most likely locations for fog is HOU and
southward, but will likely have a small window for fog at CXO and
IAH generally between 05Z-08Z. That window lasts longer the
further south you go. Once the cold front pushes through with its
northerly breeze, expect clearing conditions and the return of VFR
conditions. Northerly winds around 10-15 kt with 20-25 kt gusts
are expected through at least the early afternoon on Tuesday.

.MARINE...
Issued at 321 AM CST Mon Dec 30 2024

Brief periods of patchy dense fog are possible in the bays during
the late night and early morning hours until the next cold front
passes off the coast Tuesday morning. North to northeast winds
will prevail behind the front into midweek. A coastal trough
should then develop off the mid and lower Texas coast. Winds will
veer to the east and chances for scattered showers will re-enter
the forecast Thursday and Friday. Look for a return of onshore
winds this weekend as a warm front moves inland. 47
