.DISCUSSION...
Issued at 1233 AM CST Sun Nov 8 2026

Upper trof/low situated across ncntl Mexico. The first ejecting shortwave
(one of many) is producing a large area of precipitation between
Dallas and San Antonio. Some of this precip will probably clip
some of our northern zones in the next several hours. Additional
precipitation will probably develop further south across south
Texas closer to a surface trof today...some of which may track
into parts of the area later in the day. This too, will mainly be
light...and overall accumulations will be negligible the further
east (I-45ish) one goes. With abundant cloud cover, readings won`t
have much of an opportunity to warm...so we`re probably looking
at highs mostly in the 60s to low 70s depending on location.

Same general setup is in play again on Monday, with highest rain
chances across our southwest CWA. By Tuesday we`ll see the upper
low slowly lift ene across the state. Cloudiness will linger as
will lowish rain chances.

Heading into mid-late week, amplified ridging across the western
CONUS and deepening trof across the eastern CONUS will bring an an
drier northwesterly flow aloft. Looking for a cold frontal passage
Wednesday night followed by dry, cool weather for the remainder of
the week.  47

.AVIATION...
(06Z TAF Issuance)
Issued at 1113 PM CST Sat Nov 7 2026

Since the previous update, environmental and model data trends are
suggesting a somewhat more moist atmosphere than earlier expected.
Widespread SHRA in central TX is slowly drifting in our direction
tonight. It will encounter some dry air, but perhaps a little less
than previous forecasted. For now, we`ve added VCSH to the CLL
TAF, while adding PROB30s for -SHRA for CLL, IAH, HOU, and SGR.
Any rain should be light. But we cannot rule out cig/vis drops in
any -SHRA. We`ll watch data trends closely, making amendments when
warranted.

.MARINE...
Issued at 1233 AM CST Sun Nov 8 2026

Moderate easterly winds will continue through tonight, with the
highest winds and seas in the waters west of Freeport. Speeds and
seas should gradually diminish Monday and Tuesday. A cold front
will push into the waters Wednesday night followed by moderate
offshore winds, building seas, and Small Craft Advisories likely
in its wake. 47
