KEY MESSAGES

- With more sun, temperatures will run above seasonal averages, though humidity will be somewhat lower.

- Can't completely rule out a brief shower or two, but best rain chances will be offshore.

- Hazardous marine conditions (winds/seas) are expected at times, more so toward the end of the week.

DISCUSSION

Issued at 1259 AM CDT Tue Oct 6 2026

A prevailing low level east-northeast flow will persist across the majority of the area with a broad area of high pressure situated across the eastern CONUS - sending some recycled drier air into the region. Closer to the coast and further offshore, one cannot totally rule out some sct showers (better chances in the Gulf) in association with a frontal zone and coastal trof in place.

We're still keeping an eye on the disturbed weather across the southwestern Gulf. Guidance indicates this area may eventually evolve into a tropical depression in the coming days. Though there is some uncertainty in terms of the specifics...assuming it follows model trends and climatology, the most unsettled weather should remain offshore and areas to or east heading into the later parts of the week. As always...let's continue to monitor things.

Assuming any tropical shenanigans do end up being to our east, we could see some even drier and slightly cooler air sag into the area this weekend. 47

AVIATION

(12Z TAF Issuance) Issued at 534 AM CDT Tue Oct 6 2026

VFR conditions are expected throughout the period. A few to scattered mid to high clouds will prevail through the day with N to NNE winds around 5 to 10 knots, slightly higher along the coast. Winds will become light and variable later this evening.

MARINE

Issued at 1259 AM CDT Tue Oct 6 2026

Northeast winds will continue for the next several days...increasing a bit heading into late week. Caution flags are flying in the Gulf waters. A tropical depression is likely to form within the next couple of days in the southwest Gulf. The system is expected to drift east-northeastward through the middle portion of the week before turning northward. Though there is uncertainty how everything will evolve and its final destination, guidance and climatology generally favor locations further to the east of the Texas coast. We will, however potentially see some increasing winds and swells later in the week and Small Craft Advisories appear likely. 47
