KEY MESSAGES

- Warm, and more humid weather is expected through the week.

- A chance showers and thunderstorms for parts of the area Tuesday afternoon into Wednesday as a weak disturbance moves through.

- Areas of fog and sea fog during the nighttime and morning hours on a daily basis for much of the week could cause navigation/commuting hazards.

DISCUSSION

Issued at 1045 PM CST Sun Feb 8 2026

Fog is anticipated to develop nightly and into the mid-morning hours each day through mid-week. Fog will become dense at times, initially beginning along the coast and expanding inland through the overnight hours. Some locations along the coast may see fog stick around into the afternoon. While fog potential is highest through mid-week, there will be a chance of fog through Friday night. Density/coverage of fog will heavily depend on whether winds are slightly higher than what is forecast and if SST increase in response to the warmer temperatures. Both of these scenarios could limit fog potential.

Tuesday's disturbance continues to look lackluster. PWAT values still sit in the 90th percentile, but with instability essentially non-existent, may see more isolated activity and primarily showers. Timing looks more Tuesday night into Wednesday morning.

Next shot of showers may be next weekend as another upper-level disturbance passes through. With it being later in the forecast, won't get too hung up on details. We will see if models maintain the strength of this disturbance as we get closer in time.

In the meantime, warm weather will prevail with highs in the upper 70s to low 80s and nighttime lows in the upper 50s to mid 60s.

AVIATION

(12Z TAF Issuance) Issued at 615 AM CST Mon Feb 9 2026

Areas of dense fog are situated generally along and south of a Brenham-Cleveland line - with a donut hole over IAH and central Houston. LIFR/IFR conditions elsewhere will improve heading into 9-11am timeframe...and eventually back into VFR territory for the remainder of the day. Look for deteriorating conditions overnight into Tue morning for about the same locations as ceilings/visibilities fall back down. Not entirely confident, on the specifics due to some guidance indicating slightly stronger wind speeds which would point to more stratus. But there's an equal amount suggesting visibilities might look about the same as this morning. 47

MARINE

Issued at 1045 PM CST Sun Feb 8 2026

Sea fog will continue to be possible nightly through at least mid-week, and potentially through Friday night. There are some uncertainties in the forecast that could limit fog development: a more southwesterly wind tonight may limit development, and warming SSTs through the week could also limit development - but the main takeaway will be to be prepared for several days of sea fog development. Highest confidence in the fog develop with be during the late evening (8-10pm) through mid-morning (8-10am) periods, but patchy fog could linger in the southern bays/near shore waters into the afternoons.

Otherwise, expect light onshore winds and low seas through this week. A weak disturbance moving through Tuesday night may trigger some isolated showers into Wednesday morning, but overall rain chances are low this week. A potentially stronger system, with a cold front, may pass through next weekend ending the sea fog threat.
