KEY MESSAGES

Updated at 100 PM CST Mon Dec 29 2025

- A Gale Warning remains in effect for the Gulf Waters through 6 PM this evening, followed by Small Craft Advisory conditions through Tuesday morning.

- Elevated to near-critical fire weather concerns across all of South Texas through Wednesday due to the combination of low humidity, breezy winds, and dry fuels. - Widespread low temperatures in the 30s expected Tuesday night/Wednesday morning with a low possibility for isolated locations to drop below freezing.

DISCUSSION

Issued at 100 PM CST Mon Dec 29 2025

In the wake of the frontal passage this morning, much cooler and windier conditions continue across the region. Strong CAA combined with persistent cloud cover will limit daytime warming, with highs today and tomorrow generally confined to the 50s. Our breezy north-northeasterly winds will decrease ever so slightly this afternoon and evening to 20-25 mph with occasional gusts up to 30-35 mph. These conditions have slipped just below our Wind Advisory criteria, so the Advisory was cancelled. However, a Gale Warning remains over area waters through 6 PM this evening, followed by Small Craft Advisory conditions.

Speaking of the coastal waters, seas will remain elevated at 8-14 feet with swell periods of 6-9 seconds. While winds and waves will largely be longshore, elevated offshore wave heights and persistent north-northeasterly flow may still allow for a low potential of minor beach inundation/coastal flooding, particularly around times of high tide. The combination of the breezy winds, drier air, and fuels will also result in elevated to near-critical fire weather concerns, but more on this in the Fire Weather Discussion below.

Cloud cover will linger tonight, limiting radiational cooling and keeping lows in the 40s. Although, a few northern locations may briefly dip into the upper 30s. The coldest period of the week is still expected tomorrow night into Wednesday morning as surface high pressure settles over the region, allowing for clearer skies, lower winds, and more efficient radiational cooling. Widespread lows in the 30s are anticipated. Temperatures may briefly dip to near or slightly below freezing across the northern and northeastern portions of the region, particularly in sheltered and low-lying drainage, though the likelihood of widespread freezing temperatures is low. Any freezing conditions will be short-lived around daybreak.

From midweek onwards, the surface high shifts east and onshore flow gradually returns, initiating a warming trend through the remainder of the period. High temperatures will rise to the 60s and 70s by Wednesday and Thursday, with highs returning to the upper 70s to low 80s by next weekend.

AVIATION

(18Z TAFS) Issued at 1113 AM CST Mon Dec 29 2025

VFR conditions will continue to prevail throughout this TAF period. Gusty north-northeasterly winds up to around 20-30 knots gusting to 35 knots will gradually lessen to around 10-15 knots sustained with gusts up to 20 knots by this evening. However, elevated winds and gusts will likely continue through the cycle, mainly across eastern terminals.

MARINE

Issued at 100 PM CST Mon Dec 29 2025

In the wake of this morning's frontal passage, north-northeasterly winds at strong to gale strength (BF 6-8) will persist through Monday night/Tuesday morning. In addition to winds, elevated seas up to 8-14 feet continue through the overnight hours. A Gale Warning remains in effect through 6 PM this evening followed by a Small Craft Advisory through noon on Tuesday. Winds, as well as seas, will gradually lessen by Tuesday afternoon, returning to light to moderate (BF 2-4) onshore flow by midweek and persisting through late week.

FIRE WEATHER

Issued at 100 PM CST Mon Dec 29 2025

Behind this morning's frontal passage, minimum RH values will drop below 30% (into the teens across portions of the Brush Country), persisting through Wednesday. Breezy conditions combined with the very low RH and ERCs in the 25th-69th percentile will allow for elevated to near critical fire weather concerns across much of South Texas today. We have continued to maintain a Fire Danger Statement through 9PM tonight to cover the threat. Northerly winds gradually lessen heading into Tuesday. However, low minimum RH values will continue into Wednesday, supporting lingering elevated fire weather concerns through midweek. Warmer and slightly more humid conditions return by late week before a weak front propagating in by early weekend lowers minimum RH values below 30% once again across portions of the Brush Country.
