.DISCUSSION...
Issued at 1230 AM CST Tue Nov 11 2025

Look for a fairly rapid modifying trend to begin today and tonight
as high pressure moves off to the east and southerly winds resume.
This will bring back some increasing dewpoints and RH`s to the
area and some warmer temperatures as we head into midweek and
beyond. We`ll still have mid-upper ridging in place during the
work week keeping rain chances low-nil, but with the higher
dewpoints returning we might see some late night and early morning
patchy fog to deal with across some inland locations during the
second part of the work week if the overnight winds drop off
enough.

The next upper trough will dig down the West Coast then kick out
to the ENE across the Desert Southwest this weekend and into the
Plains by Monday. May see its associated surface trof/front sag
into parts of the region later Sunday and Monday bringing us our
next shot of rain. Better instability looks like it may be
situated north of the region, but we`ll keep an eye on how
guidance evolves as the week progresses.  47

.AVIATION...
(06Z TAF Issuance)
Issued at 1230 AM CST Tue Nov 11 2025

VFR for the next 30+ hours. Southerly winds resume today. Look for
some 10-20kt gusts this afternoon...highest in the CLL area.  47


&&

.MARINE...
Issued at 1230 AM CST Tue Nov 11 2025

Winds will swing back around to the southeast today as high
pressure departs the region. Though water levels will gradually
be recovering, northern parts of the bays may see one more round
of low water conditions around the next low tide cycle late in the
day and early this evening. The pressure gradient will tighten
and wind speeds will gradually increase as the day progresses.
Caution flags may be needed in the offshore Gulf waters as early
as tonight. Moderate southerly flow will prevail into the weekend.
The next weather system is expected to move into the region
Sunday into Monday. Best overall instability should generally be
situated to our north, but we`ll keep an eye on the trends as the
week progresses. 47

.FIRE WEATHER...
Issued at 1230 AM CST Tue Nov 11 2025

Low humidities, dry fuel, and some gusty southerly winds are
anticipated across portions of the area later today. A Red Flag
Warning remains in effect for the Brazos Valley where the lowest
RH`s (around 25%) and highest winds (15-20mph) should be co-
located. Elevated fire weather conditions are anticipated
elsewhere, except maybe the immediate coast. Heading into
Wednesday and beyond, we`ll see higher humidities work their way
inland as southerly winds transport some higher dewpoints into the
region from the Gulf.  47
