.DISCUSSION...
Issued at 1213 AM CST Mon Feb 23 2026

Another day of cool dry weather is in store as surface high pressure
moves through SE Texas today. Highs are still expected to reach the
60s during the daytime, dropping overnight to the 30s/upper 40s
early Tuesday morning. Afternoon RH should be slightly drier today
as well, around 15-25% for most inland areas and near 30% along the
coast. Surface winds will generally be north to northeasterly around
10 mph or less with some higher gusts. As a result, most areas
should experience elevated fire weather conditions today. Caution
should be exercised when working with open flames or operating
equipment that can cause sparks.

High pressure slides off to the east on Tuesday, thus onshore flow
returns and ushers in a warming trend through mid week. Tuesdays
highs should climb to the upper 60s/lower 70s with overnight lows in
the upper 50s/lower 60s. We`ll also see some breezy weather settle
in too as the gradient tightens from a deepening low near the TX/OK
panhandle. Temperatures for Wednesday should see a significant bump
with highs reaching the 70s/lower 80s across the area with lows
overnight generally in the 60s.

Thursday should be pretty warm during the daytime with highs pushing
the mid 80s in some spots. However, a cold front is anticipated to
push through SE Texas in the evening, briefly cooling down the
region with lows for Friday morning dropping to the upper 40s/50s.
Highs on Friday will be slightly cooler, though the day itself will
still be pretty warm with afternoon highs climbing to the 70s.
Onshore flow returns Friday night, allowing the warming trend to
resume heading into the weekend.

.MARINE...
Issued at 1213 AM CST Mon Feb 23 2026

Elevated winds and seas continue early today, generally around
15-20 knots gusting up to 25 knots with wave heights around 3 to 6
feet. Observations show sustained winds hovering near that 20
knot mark, thus decided to maintain current Small Craft Advisory
through early today to allow for more substantial improvements in
conditions. Negative water levels are anticipated in the bays,
reaching around -0.5 ft MLLW at low tide. Onshore flow returns and
strengthens on Tuesday. Caution flags and additional Small Craft
Advisories may be needed Tuesday night through early Thursday
leading up to another cold front.
