.DISCUSSION...
Issued at 106 PM CST Sun Feb 22 2026

Fair and for some, comfortable weather continues today with
plenty of sunshine, low humidity and afternoon temperatures
ranging from the mid 50s to low 60s. Breezy north to northeast
will continue this afternoon, though they are expected to weaken
by sunset as the pressure gradient decreases and with the loss of
daytime heating. It is very dry out there, with surface dewpoints
in the 20F to 30F range, bringing relative humidity down to
between 20% to 30%. Because dry conditions and breezy winds are a
poor combination for fire safety; please, use caution with fire
this afternoon.

Be prepared for a chilly night. Dry northerly winds and mostly
clear skies will result in cold conditions tonight. Overnight lows
will drop into the 30s across most areas. Near or below-freezing
temperatures are possible across portions of the Brazos Valley,
particularly in Houston and Madison Counties. The Houston metro
area and the islands will remain in the 40s.

With high pressure dominating across the Plains, and persistent
CAA, a cool start to the workweek is expected. Highs on Monday
will generally range in the mid 60s with low humidity and light to
occasionally moderate north to northeast winds.

The main weather story for the rest of the week is a trend toward
warmer conditions. Ridging aloft breaks down after Tuesday,
bringing back southerly surface flow across the area. Highs will
generally reach the 70s. Conditions will turn even warmer after
midweek as a warm front lifts across the area and winds shift
slightly to a more southwesterly component. This will result in
highs reaching the 80s Wednesday and Thursday.

A cold front will attempt to move across SE TX on Thursday;
however, no significant impacts are expected other than
temperatures dropping a few degrees by Friday. In terms of
precipitation, the only window for rain will be with the FROPA.
However, most of the forcing looks to remain to our
northeast/east. Will continue with precipitation chances as NBM
suggests with only a slight chances over the Gulf on Thursday.

Issued at 106 PM CST Sun Feb 22 2026

Moderate to strong winds continue, though they will remain below
Gale Warning criteria. North winds around 15 to 25 knots with
higher gusts and elevated seas are expected through late tonight.
Small Craft Advisories are in effect until early evening for the
bays and until early Monday for Gulf waters. While conditions will
remain below advisory levels, strong offshore winds will also
lead to low water levels over the bays, especially during low
tides through Monday. Onshore winds return by Tuesday as the high
pressure shifts to our east. Winds may become moderate to strong
at times through the rest of the workweek.
