.DISCUSSION...

Issued at 127 PM CST Thu Dec 11 2025



Southeast winds are in the process of resuming across the area. As

such, we'll see increasing dewpoints which will likely lead to 

some fog development overnight. Patches of dense fog are a 

possibility...esp along and west of I-45. Otherwise, warmer with

increasing cloud cover on Friday with a continued influx of Gulf 

moisture. 



Periods of fog & sea fog will remain in the fcst (mainly the nighttime

& morning variety) until the next passing front eliminates those 

chances Saturday night into Sunday morning. Chances for some 

scattered pockets of -ra/shra will gradually increase as the day 

progresses Saturday and will be maximized along the frontal 

convergence Saturday night. Precip will be ending for most all 

inland locations Sunday morning as the front pushes offshore.



There is some pretty cold air behind this system, though with the

center of the 1040-1045mb high taking a more SE track toward the 

Midwest and Tennessee Valley, we'll get just the western periphery

of it. Even then, it appears areas east of a College Station-Kingwood-

Anahuac line could get some freezing temperatures Sunday night 

(26-32F). 



A gradual warm-up will then begin Monday night through midweek as

high pressure moves off to the east and a southeast flow resumes.

Guidance is still depicting the next mid-upper trof advancing

toward the area late Tue & Wed bringing another shot of some rain

for some locations.  47

.AVIATION...

(06Z TAF Issuance)

Issued at 1106 PM CST Thu Dec 11 2025



Stratus beginning to develop around the area, mainly impacting

from IAH coastward for now. No fog at TAF sites yet, but farther

down the coast, VCT has come down to 3/4SM. Expectation remains

that flight conditions will continue to degrade through the night,

though the details will likely need to be adjusted based on the

specific evolution of the night.



Conditions should begin to improve within a few hours of sunrise,

and gradually return to VFR for the afternoon. It is beyond the

scope of this cycle, but eventually will have to deal with the

return of degraded flight conditions late Friday night, and the 

onset of some rain chances Saturday.

.MARINE...

Issued at 127 PM CST Thu Dec 11 2025



Winds are in the process of returning to an onshore direction and

expect these to continue through Saturday night. Increasing moisture

may begin to lead to some patchy sea fog later tonight, followed 

by greater chances Friday night into Saturday night. Scattered 

showers will begin to pop up Saturday into Saturday night ahead of

an approaching cold front. This front will move through the 

coastal waters late Saturday night or early Sunday morning, ending

the sea fog threat and ushering in moderate to strong northeasterly

winds and building seas for Sunday. Small Craft Advisories will 

be needed. Winds and seas gradually diminish Monday, and return to

a southeast direction by Tuesday.  47
