KEY MESSAGES

- Areas of fog through through the early morning hours, and then possible redevelopment tonight into Wednesday morning.

- Dry conditions with a gradual warming trend are expected through much of the work-week. By mid-week readings may flirt with near record highs at some locations.

- Rain chances low during the work week. Maybe some slight increases heading into Saturday in advance of another Pacific front.

DISCUSSION

Issued at 1215 AM CST Tue Feb 17 2026

Ridging aloft and southerly winds at the surface will lead to warming weather through the work week. Afternoon high temperatures today will rise into the mid to upper 70s, and then into the upper 70s to low 80s on Wednesday. A boundary will approach, then stall near the I-35 corridor Thursday into Friday which will strengthen WAA across SE Texas leading to high temperatures into the low to mid-80s. A passing upper-level disturbance with associated Pacific-based cold front may pass through the area Saturday or Sunday, bringing a cool down to near seasonal weather for the weekend.

Main forecast concern over the next few days will be the potential for patchy to areas of fog/low clouds to develop nightly through at least midweek. Any fog that develops will scatter out by the mid- morning hours giving way to mostly sunny conditions for the afternoon. SE Texas will remain rain-free through mid-week, then some streamer showers will be possible Thursday/Friday as daytime heating and increasing moisture come into play. Shower activity is also possible with the passage of the weekend cold front, but coverage is looking minimal at this time.

AVIATION

(12Z TAF Issuance) Issued at 515 AM CST Tue Feb 17 2026

Areas of dense fog and low ceilings are impacting terminals near and west of I-45 this morning. Expect conditions to gradually improve after 15Z, but MVFR ceilings may linger through 17Z for northern terminals. Southerly winds this afternoon will be breezy with 10-15 kt sustained winds and gusts in the 20-25 kt range through the afternoon. Winds remain a bit elevated going into the evening/overnight hours. Another round of fog and low ceilings is anticipated overnight into Wednesday morning. Where the winds remain elevated overnight will play a role in who experiences low ceilings rather than low visibilities, which is most likely for northern terminals (e.g. CLL/UTS). Either way, widespread IFR/LIFR conditions are anticipated overnight into Wednesday morning.

MARINE

Issued at 1215 AM CST Tue Feb 17 2026

Onshore winds around 10-15kt will prevail through this week with seas around 2-4ft today, and then 3-5ft beginning Wednesday. There may be occasional higher gusts to near 20kt during the overnight periods in the offshore waters tonight and Wednesday night. A weak front may slide through the coastal waters this weekend bringing a northwesterly wind shift, but forecast confidence is low on exactly when this front moves through.

Will need to monitor the potential for some patchy fog the next few nights. Increasing winds and ocean temperatures will limit the potential over the waters, but inland fog may spill out into the northern parts of the Bays during the predawn hours.
