DISCUSSION

Issued at 1126 AM CST Sun Feb 8 2026

Generally pleasant conditions are expected to persist through the forecast period for Deep South Texas and the Rio Grande Valley. High temperatures are expected to remain above average for this time of year with highs in the upper 80s possible each day due the the influence of a mid-level ridge to the south of the region. Rain chances will remain very low (less than 10%) through the period, even through a mid-level trough does pass to the north of the area Tuesday night into Wednesday.

Another round of fog is possible tonight as the clear skies and weak winds will provide a favorable environment for fog. The SREF model currently highlights the Northern Ranchlands for the best chances for the development of fog. Areas along the coast have a medium chance (around 40%) for the development of fog overnight. With similar conditions expected to repeat for the next several nights, more chances for the development of fog remains possible each night. A Dense Fog Advisory or a Special Weather Statement for fog is possible tonight.

Lastly, along the coast, while the risk of rip current is currently low and is expected to be low through Monday. By Tuesday evening, an increase in swells and winds over the Gulf waters could lead to an elevated risk of rip currents becoming more likely.

AVIATION

(00Z TAFS) Issued at 513 PM CST Sun Feb 8 2026

Predominately VFR conditions are forecast through the TAF period, though MVFR to IFR conditions will be possible early Monday morning. Southeasterly winds are forecast to become light and variable tonight before picking up out of the southeast again by mid-morning. Cloud cover is forecast to increase overnight, with MVFR ceilings possible, especially at BRO. With the increased cloud cover, confidence is lower on visibility reductions tonight, with the majority of models keeping visibilities above 6 miles. Probabilistic guidance is now keeping the probability of MVFR to IFR visibilities below 25% tonight.

MARINE

Issued at 1126 AM CST Sun Feb 8 2026

Generally favorable conditions are expected for the duration of the forecast period for the Laguna Madre and Gulf waters with light to moderate southeasterly winds and low to moderate seas. Some Small Craft Exercise Caution conditions are possible for brief periods of times during the afternoons especially towards the end of the forecast period.
