DISCUSSION

Issued at 1211 AM CST Sat Dec 28 2025

We will see another day of above normal temperatures ahead of a strong cold front expected late tonight (Sunday night). Highs will surpass 80 degrees in majority of the region with the Brush Country hovering around 85-87 degrees.

As the cold front approaches, winds will significantly increase and temperatures will plummet abruptly and remain cooler through most of the week. Highs will only reach into the 50s during the early portions of the week. A gradual warming trend takes over as on shore flow returns during the latter portions of the week. The coldest night will be Tuesday night into Wednesday morning as lows will be in the 30s across much of the region with some areas approaching freezing. The northern portions of the region have a low (<20%) chance for temperatures at freezing or below freezing therefore, confidence is low for this to occur. Not ruling out the possibility for the drainage areas to drop to or below freezing by daybreak, though this would likely only be for an hour or two at the most. The front will bring moderate rain chances with the low possibility for thunderstorms (20-25%) located along the front as it pushes through.

In regards to the winds, they are expected to pick up significantly across the region Sunday night and persist through Monday evening. Winds will be around 20 to 30 mph with gusts to 45 mph through much of the day especially over the waters. This prompted the issuance of an areawide Wind Advisory and an upgrade to a Gale Warning during this package. Wave heights (9-14 ft) are expected to increase as well as swell periods (6-8 seconds) in which combined with the winds would lead to an increased potential for minor coastal flooding.

AVIATION

(06Z TAFS) Issued at 1211 AM CST Sun Dec 28 2025

Tonight expecting LIFR/IFR CIGs and possibly MVFR VSBYs similar to last night. Winds out of the southeast generally around 10-15 knots indicating low CIGs are more likely than fog. VFR conditions in the afternoon and evening. A cold front will approach the northern sites towards the end of this TAF period with gusty northerly winds, showers, reduced VSBYs and CIGs.

MARINE

Issued at 1211 AM CST Sun Dec 28 2025

Expect a gentle to moderate (BF 3-4) onshore flow ahead of our next cold front late Sunday night/early Monday morning. This front will result a 60-75% chance of precipitation and in winds shifting to the north-northeast, increasing to a near gale to gale strength (BF 7-8) through Monday night/Tuesday morning. In addition to winds, seas are expected to build up to 15 ft offshore. A Gale Warning will go into effect from 3 AM to 6 PM Monday. Winds will gradually lessen Tuesday, returning to gentle to moderate (BF 3-4) onshore flow by midweek.

FIRE WEATHER

Issued at 1211 AM CST Sun Dec 28 2025

Southeasterly winds of 10-15 mph, relative humidity values above 40%, and Energy Release Components (ERCs) in the 25th-49th percentile will negate fire weather concerns through the remainder of the weekend. A strong cold front will move through late Sunday night into Monday morning, resulting in medium chances (50-60%) for precipitation along the front. In the wake of the front, minimum RH will drop below 30% (into the teens across portions of the Brush Country) Monday through Wednesday. Breezy conditions combined with the very low RH and ERCs in the 25th-69th percentile will allow for elevated fire weather concerns across much of South Texas Monday and Tuesday afternoon.
