Issued at 148pm CST Wednesday Feb 25 2026

Another warm and dry day across Southeast Texas with breezy to windy southerly winds in response to a tightening pressure gradient over the southern Plains. A Wind Advisory remains in effect for areas roughly from I-10 coastward through 6pm this evening. While winds will begin to weaken later this afternoon; a moderate west to northeast LLJ will still strengthen over the region tonight. Consequently, expect southerly winds around 15 to 25 mph, gusting to 30-35 mph through early this evening. Conditions will remain breezy with gusts up to 25 mph through early Thursday. Higher gusts are expected across coastal counties and along the islands.

A surface low currently located across North Texas will continue to move east-southeast tonight, dragging a weak cold front across SE TX on Thursday. The arrival of this weak cold front will bring weaker winds, warmer conditions and increased cloud cover due to rising Gulf moisture. Highs will generally reach the mid 80s. This front is forecast to move through the area by midday, reaching the coast by late Thursday night. Because light onshore winds will likely persist into the evening, patchy fog may develop along the coastal counties. Overall, this is a weak and generally dry frontal passage; aside from some very light showers near the coast, the region should remain dry.

Behind the front, little change is anticipated. Conditions will remain dry and warm through the weekend as a mid to upper level ridge strengthen over the region, resulting in above normal temperatures to close out February.

Issued at 148pm CST Wednesday Feb 25 2026

A surface low over North Texas and high pressure to our east will continue to bring moderate to strong onshore winds and seas around 5 to 10 ft across the Upper TX coast through early Thursday. Small Craft Advisories remain in effect for the bays and Gulf waters through 6am Thursday. Winds will gradually weaken by early Thursday ahead of the cold front; however, seas may take longer to subside through the day. Therefore, advisories could potentially be extended through midday. The front will be moving over the waters by Thursday night; increasing the potential of patchy fog ahead of it. A few light showers will also be possible ahead and along the front, particularly over the Gulf waters. Light onshore winds will quickly resume on Friday and will persist well into the upcoming week.
