DISCUSSION

Issued at 1245 PM CDT Wed Oct 28 2026

Mostly rain-free conditions and near to slightly above normal temperatures will prevail across Deep South Texas heading into early November. However, limited precipitation chances, mainly along and west of US-281, are expected on Thursday as the remnants of Tropical Storm Vance move into West and Central Texas. A few showers cannot be ruled out closer to the coast, but the best ingredients will reside further inland. Otherwise, expect rain- free conditions heading into next week. For those participating in any outdoor festivities late this week and weekend, expect afternoon high temperatures in the upper 80s and low 90s and evening temperatures in the low to mid 80s. Winds will remain out of the east southeast with wind speeds around 10 MPH and occasionally higher gusts.

Guidance continues to indicate a deepening upper level system translating across central CONUS by early to mid week next week, which will likely usher in a cold front, and potentially some low rain chances, across Deep South Texas. However, there remains uncertainties in the evolution and timing of this system so continue to check back for updates to the forecast.

AVIATION

(18Z TAFS) Issued at 1245 PM CDT Wed Oct 28 2026

VFR will prevail through the forecast period at all TAF sites. Isolated showers or storms cannot be ruled out this afternoon, but confidence is too low to warrant a mention in the TAF. Otherwise, southeasterly winds around 10 knots this afternoon will fall below 5 knots tonight into early tomorrow morning.

MARINE

Issued at 1245 PM CDT Wed Oct 28 2026

Generally favorable marine conditions will prevail through the forecast period with light to moderate southeast winds and low to moderate seas. Isolated showers and thunderstorms may develop through tomorrow before rain-free conditions return into the weekend and early next week. Locally enhanced winds and seas are likely within any showers and storms.
