KEY MESSAGES

- Cool and dry this weekend. - Hazardous marine conditions expected with elevated winds/seas today. Slowly improving conditions are anticipated later in the day into Sunday.

- Warmer temperatures return next week, but just seasonable in nature.

DISCUSSION

Issued at 1235 AM CDT Sat Oct 17 2026

Winds are still elevated behind the cold front, particularly over the Gulf waters and coast. As high pressure builds in the wake of FROPA, the surface pressure gradient loosens and the winds weaken this afternoon. The rest of the weekend is cool and dry, with highs in the upper 60s-low 70s, lows in the 40s/50s and low RH's.

The approaching workweek is similarly temperate, with models largely in agreement. Surface high pressure transitions further to to our E bringing an easterly fetch of winds across our area for much of next week. This subtle difference from our typical SE flow is enough to stifle moisture development and rain chances and helping to keep PWATs around and below 1" for much of the region. The main concern for rain chances, albeit low, will be mostly offshore Monday-Wednesday. Without reprieve from rain (and only partly cloudy mid-upper levels), high temperatures gradually climb to the 80s by Wednesday, and lows in the mid 50s inland and upper 60s towards the coast.

AVIATION

(12Z TAF Issuance) Issued at 507 AM CDT Sat Oct 17 2026

VFR conditions will prevail throughout the TAF period with gusty northerly winds persisting into the afternoon before gradually subsiding. Sustained winds through the late morning will be in the 10-15 kt range with gusts in the 20-25 kt range...winds will be higher along the coast. Satellite reveals scattered to broken upper level clouds approaching from the west, but these won't have any impacts on aviation. Expect winds to become light going into the evening hours and gradually transitioning to northeasterly going into Sunday.

MARINE

Issued at 1235 AM CDT Sat Oct 17 2026

Winds behind the front are still strong over the bays and nearshore waters and a Gale Warning remains in effect through the morning hours. These winds are from the N between 25-30 kts, gusting up to 40 kts. Seas are between 5-12 ft and should gradually diminish later this afternoon into Sunday. Gales will probably transition to SCA's later today and possibly tonight offshore. A moderate easterly fetch sets up across the northern Gulf Coast for much of the work week. SCEC/SCA's may be required at times Mon-Wed in the offshore Gulf waters.
