.SHORT TERM...
(Today through Tuesday night)
Issued at 1210 PM CST Sun Nov 23 2025

High pressure ridging down from the north bringing a slightly
cooler and drier day with most of the forecast area seeing sunny
skies.

Progressive pattern however will bring back changes on Monday.
High pressure will shift off to the east with an upper level
trough moving out of the southwest US. This will allow winds to
veer to a southerly direction and increase that will push a warm
front north across the forecast area during Monday, and with it a
moist and moderately unstable Gulf air mass.

Progs show PWAT at or above 1.5 inches by Monday afternoon, which
is over the 90th percentile, and mean layer relative humidity
values over 70 percent. Scattered showers and a few thunderstorms
will develop with the daytime heating by afternoon.

The forcing from the upper level trough and ongoing convective
outflow boundary moving in from east Texas will allow a line of
showers and thunderstorms to reach the forecast area of southeast
Texas and west central Louisiana between 8 and 9 pm local.
Moderate instability is progged to hang around as this system
reaches the forecast area, to go along with good shear values and
favorable lapse rates. Therefore, the line of storms will have
some severe potential with damaging winds the main threat,
although any discrete broken features ahead of along the line will
have the best chance for rotation with tornadic potential.
Therefore, a Slight Risk (level 2 out of 5) has been outlined
northwest of a Beaumont to Alexandria line.

Also, with the highly anomalous moisture values, the stronger
storms will have the potential for high rain rates in a short
period of time with progs showing activity with rainfall rates of
1 to 2 inches per hour and this will bring about some risk of
urban type flooding.

The line is expected to gradually weaken during the night as it
moves further east into southwest Louisiana and Acadiana.

A cold front will catch up to this activity on Tuesday afternoon
pushing the moisture off to the east and south ending rain
chances. Much cooler and drier conditions will then filter into
the forecast area.

.LONG TERM...
(Wednesday through Sunday)
Issued at 1215 PM CST Sun Nov 23 2025

High pressure will then ridge down into the forecast area from the
Plains bringing a mix of modified Canadian and Pacific air that
will bring seasonably cool and dry conditions through
Thanksgiving.

Still some differences in the details so the forecast for next
weekend is of low confidence. However, it looks like it could be
rather active as southerly flow returns and robust southern jet is
noted overhead.

.AVIATION...
(18Z TAFS)
Issued at 1140 AM CST Sun Nov 23 2025

Low clouds have finally cleared out of KAEX with all sites now at
vFR conditions that will last for the remainder of the afternoon.

High level clouds will be moving in tonight along with boundary
layer winds staying up enough to preclude any significant fog
issues with mainly VFR conditions continuing.

A warm front will move north across the forecast area on Monday
with increasing winds from the southeast and increasing low level
clouds. Conditions are expect to remain VFR through this TAF
cycle, however by Monday afternoon, MVFR conditions with
developing shower activity will be possible.

.MARINE...
Issued at 1148 AM CST Sun Nov 23 2025

Winds will become onshore and increase to moderate levels on
Monday as high pressure moves off to the east and low pressure
develops over the Plains. Rain chances will also increase during
Monday into Monday night ending on Tuesday as a cold front moves
into the coastal waters. Winds will become offshore behind the
front on Tuesday and increase by Wednesday with the possibility
of small craft advisory conditions.

.FIRE WEATHER...
Issued at 1145 AM CST Sun Nov 23 2025

A warm front will move across on Monday bringing back southerly
winds along with an increase in temperatures and moisture. Rain
chances will increase late in the day into tomorrow night as an
upper level disturbance moves overhead. A cold front is then
expected on Tuesday ending rain chances, bringing cooler and drier
conditions through Thanksgiving.
