.DISCUSSION...
Issued at 154 PM CST Sun Nov 9 2025

Several hazards are ongoing or anticipated in the wake of this
morning`s front. Fire weather wise, RH values have dropped into
the low to mid 20% range for much of the area, with the driest air
behind the front set to arrive Monday, while winds will be on the
downward trend, dry air and windy conditions may result in
critically drier fuels...therefore, the Red Flag Warning will
continue for the entire area tomorrow.

Windy conditions across the land will gradually diminish this
evening into the overnight hours with northerly winds around 10
mph expected for much of the day Monday. Gusts to around 20-25 mph
will be possible during the morning hours. A Wind Advisory remains
in effect through this evening.

Colder northerly winds will bring strong CAA into Southeast Texas
tonight into Monday morning (and again Monday night into Tuesday
Morning). Low temperatures are anticipated to dip below freezing
for a few hours early Monday morning in Houston, Madison, Trinity,
Walker, and Polk Counties which has prompted a Freeze Warning for
tonight into Monday morning. While these are the areas that have
the highest probability of experiencing freezing temperatures for
more than two consecutive hours, I do want to point out that
locations north of I-10 (particularly north of the metro and in
Brazos Valley) could reach freezing temperatures for a shorter
duration tonight into Monday morning. That being said, if you live
in a location vulnerable to freezing temperatures, please remember
to protect the 4 Ps (people, pets, pipes, plants). We are
continuing to monitor for the potential of another night of
freezing temperatures Monday night into Tuesday morning, which may
necessitate another Freeze Warning.

Temperatures begin to recover by midweek as onshore flow returns
Tuesday and brings in our typical warmer humid airmass. Highs are
expected to return to the 80s by Wednesday, with 80 degree highs
continuing through the end of the week.

Rain chances remain nil, especially with a cooler and drier
airmass in place at this time. May see an uptick in PoPs later in
the period once persistent onshore flow becomes established and
moisture returns to SE Texas.

.AVIATION...
(12Z TAF Issuance)
Issued at 420 AM CST Sun Nov 9 2025

A cold front is pushing through Southeast Texas early this morning
with gusty northerly winds in its wake. Any lingering fog or low
ceilings will clear out over the next couple of hours as the front
pushes offshore. Northerly winds today will be sustained in the
15-20 kt range with 25-30 kt gusts (higher winds closer to the
coast). Elevated winds (10-15+ kt) stick around into late Sunday
night/early Monday morning. VFR conditions prevail throughout the
TAF period following the frontal passage.

.MARINE...
Issued at 154 PM CST Sun Nov 9 2025

Strong north winds and building seas will continue through late
tonight and possibly into Monday morning. Small Craft Advisory
conditions are expected in the bays through late tonight. Gale
conditions are expected to continue on the Gulf through the
night. The strong north winds will also generate low water
conditions late Sunday and Monday on both Galveston Bay and
Matagorda Bay, with more severe low water conditions anticipated
on Galveston Bay, where a low water advisory has been issued.
These conditions are expected to be an issue at low tide on
Sunday, but also in upper portions of the bay and the Houston Ship
Channel through Monday`s low tide cycle as well.

&&

.FIRE WEATHER...
Issued at 154 PM CST Sun Nov 9 2025

Critical fire weather conditions are expected to continue this
afternoon and Monday due to the dry air and gusty winds,
prompting a Red Flag Warning across Southeast Texas as any new
fires could spread rapidly in this environment. At greatest risk
will be areas of dense, grassy fuels, which will respond most
quickly to the surge of dry air. Winds will begin to diminish
Monday, but humidity will be even lower and fuels will have
additional time to dry. A Red Flag Warning continues across the
area Monday, as there may be a window in which critical fire
weather conditions materialize again. Continue to obey all local
burn bans.
