.DISCUSSION...
Issued at 1156 AM CST Fri Feb 20 2026

A stationary boundary is currently draped across northern portions
of the CWA. Warm and humid conditions are expected to persist ahead
of the boundary, with highs near 80 degrees across central and
southern portions of the forecast area, while areas to the north may
struggle to to warm beyond the upper 60s. Weak low-level lift along
and just north of the boundary may support a low chance (20-40%)
chance for scattered light showers. In addition widespread low-level
moisture will continue to support periods of fog once again tonight
into early Saturday prior to the frontal passage. The highest risk
for dense fog will be across areas south of I-10 and coastal
portions of the area.

A stronger cold front is expected to move through Southeast Texas on
Saturday. Behind the front, a reinforcing surge of high pressure
will overspread the region, bringing a notable increase in northerly
winds, a rapid drying trend, and decreasing temperatures by late
afternoon and evening. High temperatures on Sunday and Monday are
expected to generally be in the low-to-mid 60s, with lows reaching
the upper 30s to mid-40s. By the middle of next week, the surface
high shifts east and onshore flow redevelops, allowing the warmer
and more humid conditions to return.

.AVIATION...
(00Z TAF Issuance)
Issued at 528 PM CST Fri Feb 20 2026

Tonight will be similar to last night with expanding IFR to LIFR
conditions for much of the region. Currently, VFR conditions
remain in place for much of the region with some few to scattered
low clouds in place with ceilings around 5000-6000ft, with the
exception of GLS where LIFR conditions remained through the day
today. Expecting lowering ceilings to IFR conditions (around
600-800ft) between 3-5z for IAH southwards, then up through CXO
and UTS by 6-9z. Conditions will crash down to LIFR conditions
with CIGs near 200-400ft within an hour or two after dropping to
IFR. Patchy, but dense, fog will also be a possibility through
the night into the early morning hours of tomorrow. CLL may be
able to stay at MVFR levels through the night, but a period of IFR
conditions due to ceilings will be possible between 8-10z.

A cold front is expected to pass through the area during the day
on Saturday ushering in a northerly wind shift and gradually
improving ceilings. There will be isolated light rain showers
developing ahead of the front along the coast, but coverage will
be limited enough to keep from putting in the TAFs. FROPA will
happen at CLL around 10-13z, at IAH between 13-15z, and then off
the coast by 15-18z. CIGs will improve to MVFR levels (around
1500ft) within 2-3 hours post front, and then to VFR level (few to
scattered low clouds still possible, but mostly mid- level clouds
remaining). Expecting VFR conditions returning to all of the area
between 21-00z.

Northwesterly winds around 10-15kt with gusts to 20-25kt are
expected to develop during the afternoon hours across much of the
region. The winds gusts should end by sunset for most areas
expect the coast (GLS) where the gusty winds will prevail into
Sunday morning.

.MARINE...
Issued at 1156 AM CST Fri Feb 20 2026

Areas of fog will continue through tomorrow morning before a frontal
boundary pushes offshore. Increasing northerly winds and building
seas are expected by late Saturday afternoon into the evening hours
in the front`s wake. Winds are likely to gust to gale force while
seas build to 6-10 feet. Therefore, a Gale Watch is currently in
effect through from 00-12Z Sunday. Conditions should improve late
Sunday into Monday, with onshore flow returning by Tuesday.
