.DISCUSSION...
Issued at 1010 PM CST Sun Dec 7 2025

A cold front that pushed through Sunday afternoon has ushered in
chilly, breezy conditions for the region. A Wind Advisory is in
effect for the Barrier Islands through around sunrise Monday where
wind gusts of up to 30 mph will be possible. While mostly cloudy
skies will prevail through Monday morning, skies will clear out
by the early afternoon hours. High temperatures will be in the mid
to upper 50s north of I-10, and then upper 50s to low 60s along
and south of I-10. Clear skies and light winds will lead to
temperatures dropping into the mid to upper 30s for most of the
region with the coast/Houston Metro staying in the low to mid 40s
and the Piney Woods dropping to near freezing.

There will be a gradual warm-up through midweek as high pressure
slides over the area and then to the east ushering in a southerly
flow. High temperatures on Tuesday will be in the low to mid 60s,
then low to mid 70s on Wednesday, and then mid to upper 70s (and
even some low 80s possible south of I-10) on Thursday. There is
potential of another cold front passing through the region late
week or this weekend, however guidance has been very uncertain on
the timing.

choppy to rough bay waters, and seas rising to 5-7ft nearshore and

be potential for patchy fog developing nightly by midweek.
