.DISCUSSION...
Issued at 1044 PM CST Sat Dec 6 2025

Moist onshore flow has led to the development of patchy, dense fog
across much of the area. A Dense Fog Advisory is out through 7am
for most areas along and south of I-10, and then along and east of
I-45. As the night unfolds, the Brazos Valley may get included in
the Advisory. Conditions will improve through the morning, but the
Advisory may get extended along the coast into the mid-morning
hours.

A dry cold front will push through the coastal waters late Sunday
afternoon ushering in cooler, drier conditions. Ahead of the
front, we will likely rise into the low to mid 70s across much of
the area, but we will be cooling down Sunday night down into the
upper 30s to mid 40s. And add in a breezy north wind, conditions
will feel even chillier. This chilly weather will continue into
the work week with highs in the mid 50s to low 60s on Monday and
overnight lows into the mid 30s to low 40s Monday night (with some
areas in the Piney Woods dropping to near freezing).

A gradual warm-up is expected through midweek as winds become
southerly with highs in the mid to upper 60s on Tuesday, low to
mid 70s on Wednesday, and then some low 80s possible returning by
Thursday. Our next cold front may arrive late Thursday into
Friday, but at this point it is also looking like a dry front like
Sunday`s.

.AVIATION...
(00Z TAF Issuance)
Issued at 455 PM CST Sat Dec 6 2025

Light VRB winds expected through Sun morning. Cigs are expected
to lower to IFR-MVFR tonight for much of SE Texas, with some
sites possibly lowering to LIFR at times. Areas of patchy to dense
fog is expected to develop tonight into Sun morning and will lead
to visibilities of less than 1 mile during the overnight and
early morning hours for several locations, to include IAH/HOU.
Conditions will gradually improve after 14Z with most of the fog
burning off shortly after that hour. Cigs will also lift gradually
around that hour and are expected to scatter out by the afternoon
hours as drier air moves in after the passage of a dry cold
front. NW winds at 10-15kt will develop Sun afternoon/evening in
the wake of the front and gusts could reach 20-25kt at times.
Brief moments of llvl wind shear is also possible.

.MARINE...
Issued at 1044 PM CST Sat Dec 6 2025

Dense fog will continue to be possible through the morning hours
in the Bays and nearshore waters with some patchy fog possibly
lingering into the mid-morning or late morning hours. Light
onshore winds will prevail through the early afternoon, but a cold
front will usher in strong northerly winds (sustained 20-25 kt
with gusts to 30-35 kt) starting in the late afternoon through
Monday morning. These winds will cause rough bay waters and seas
to climb to 4-6ft in the nearshore waters and to 5-9ft in the
offshore waters. A Small Craft Advisory is in effect for all
waters beginning at 4pm Sunday through Noon Monday. Light
northeasterly winds are expected to develop Monday night with
light onshore winds developing Tuesday that continue through
midweek. These onshore winds will lead to an increase in moisture,
so the return of fog is possible by midweek.
