.DISCUSSION...
Issued at 1143 AM CDT Mon Oct 13 2025

Tranquil weather conditions will prevail for the first half of the
week as a persistent mid to upper level ridge continues to limit
rain chances across Southeast TX. Light winds will continue over
the region, along with high temperatures in the upper 80s to
lower 90s and low temperatures in the 60s for much of the inland
portions and in the lower to mid 70s along the coast. Luckily,
pockets of dry air will be moving across Southeast TX from time to
time through mid-week, leading to fairly pleasant early mornings
and evenings.

By Thursday, low level moisture is expected to rise a little and
the ridge will weaken as a mid to upper level trough moves across
TX. Lower heights and an increase in cloud cover will help bring
down the temperatures a couple of degrees, roughly in the upper
80s for much of the region. We will have another gentle rise in
moisture on Friday as a stronger mid to upper level trough moves
across the Rockies and into the Southern Plains. With higher
moisture and less subsidence aloft, we could have the opportunity
for isolated to possibly scattered showers and isolated
thunderstorms on Friday. An associated cold front will then move
over Central TX on Saturday and there`s the potential for it to
reach Southeast TX sometime late Saturday or early Sunday. This
would once again provide the opportunity for some rain, depending
on how south the front actually tracks. Another thing to note with
this front is how hot it will feel that day, as low level moisture
converges before the frontal passage. As of today, highs could be
in the lower 90s for much of the inland portions along with heat
indices in the upper 90s for several spots. Conditions and
temperatures on Sunday will depend on whether the front pushes
into the coastal waters or stalls near Southeast Texas.

Issued at 1143 AM CDT Mon Oct 13 2025

Light onshore winds today, then turning east northeast Tuesday
into Wednesday. Onshore winds return Thursday and continue into
the upcoming weekend. Seas will be 3 feet or less for the next
several days. Rain chances could return Thursday night or early
Friday and may continue into Saturday as a cold front makes its
way across Central TX and into Southeast TX. Low confidence as to
whether the front will make it into the coastal waters on Sunday
at this time.

.FIRE WEATHER...
Issued at 1238 AM CDT Mon Oct 13 2025

With SE winds today, RH`s should be a touch higher than previous
days - generally bottoming out 35-40% inland & 50% coast. Tuesday
and Wednesday we`ll see slightly drier air move into the area from
the northeast. With continued warm temperatures, RH`s will drop into
the 27-37% range. Wind speeds will still be below Red Flag Warning
criteria, but considering the dry fuels in place...please exercise
caution when working with open flames/equipment that can cause
sparks, especially in dry spots. The Texas A&M Forest Service Fire
Danger index is in the moderate-very high territory.
