.DISCUSSION...
Issued at 129 PM CST Sat Jan 10 2026

Temperatures are running 20-30F lower today than they were this
time yesterday thanks to last nights frontal passage. Winds will
lose their gustiness overnight, though sustained speeds 5-13mph
should linger for a good part of the night. Look for overnight
lows to fall into 35-45 degree range for most of the region
(lowest inland). Areas up near Houston County may see a brief,
light freeze. Plenty of sunshine, low RH`s and lighter winds on
Sunday with highs topping out in the upper 50s-low 60s.

The southwestern portion of the parent mid-upper trough of last
nights front will cut off and retrograde back toward the Baja
area. It`ll eventually kick out on Monday, track across Texas
Tuesday, then become absorbed by a deepening trough to our east
on Wednesday. We should see some increased mid-upper level cloudiness
as it approaches, and perhaps some virga or a few sprinkles as it
gets close...but overall quality llvl moisture return doesn`t
look favorable for anything of significance. On the backside of
this system, we`ll see another cold front pass through late
Wednesday or Wednesday night. It`ll come through dry.

High pressure behind this front will pass off to the east later
Thursday. Southerly flow then resumes. Combination of some returning
Gulf moisture, and maybe some mid-upper Pacific moisture, might
allow for some slightly better chances of rain in advance of
another front forecast to move through next Saturday.  47

.AVIATION...
(00Z TAF Issuance)
Issued at 513 PM CST Sat Jan 10 2026

VFR throughout, putting focus squarely on gusty north winds. Winds
a little west of due north tonight, and gusts in the 20s continue
across SE TX. Those gusts should gradually drop off this evening
and winds diminish slightly, but remain in the ballpark of 10 kts
through the night. Tomorrow, look for winds to continue at roughly
that same speed, but veering slightly more towards due north, and
maybe even a little east of due north at times late in the period.

Only exception to this is GLS. With fetch there off Galveston
Bay, winds will be slower to diminish. Expecting around 20G30kt
tonight and gusts holding much deeper into the night than inland,
with gradual diminishment into the teens tomorrow. Direction
trends should be the same as elsewhere.

.MARINE...
Issued at 129 PM CST Sat Jan 10 2026

Moderate to strong north winds and elevated seas will continue
into Sunday morning before gradually diminishing during the day
Sunday. This offshore flow has pushed some water out of the bays
and mariners should anticipate negative tide levels...especially
around low tide cycles through late Sunday morning. Small Craft
Advisories and a Low Water Advisory will remain in effect til
about noon Sunday. High pressure will move overhead early next
week allowing for light winds and continued subsiding seas. The
next cold front is expected to push into the waters late Wednesday
or Wednesday night. SCAs look probable behind this front too. 47
