.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...
(18Z TAF Issuance)
Issued at 1156 AM CST Fri Feb 20 2026

Tricky forecast with mixed flight categories across east Texas. MVFR
CIGs or lower expected to linger throughout the rest of this
afternoon into evening with IFR/LIFR conditions developing tonight
through tomorrow morning as a cold front moves through the region.
Have lower confidence with VSBYs from fog but expecting similar
conditions as this morning until the front rolls through. VFR
conditions should quickly return after FROPA around 14-16Z. Have
opted to leave RA out of TAFs with low confidence and probabilities
238-313-335>338-436>439.

     355.
