602am CDT Fri Mar 13 2026

Issued at 142am CDT Fri Mar 13 2026

Onshore flow returns to the region today leading to a gradual increase in surface moisture, but still remaining relatively dry across inland locations. Many locations will see high temperatures on Sunday afternoon approach the century mark, while the relatively cool waters along the coast will keep Spring Breakers on our local beaches in the upper 70s/low 80s.

Another strong cold front is still looking to arrive late Sunday night/early Monday morning, with gale conditions for mariners and quite the blustery Monday morning commute. Additionally, latest NBM continues to bring temperatures down on Monday, with highs struggling to climb into the 60s in the Victoria Crossroads. Tuesday's mornings lows continue to expand on upper 30s across the northern Brush Country and Victoria Crossroads. With RH dropping down to as low as 10% Monday afternoon, fire and wind headlines may be needed considered for later forecast packages this weekend. Looking ahead, we see an upward trend with temperatures as onshore flow returns.

Gentle to moderate (BF 3-4) southeasterly winds tonight will continue through Saturday afternoon with 2-3 ft seas. Winds will then turn more southerly Saturday afternoon and increases to fresh strength (BF 5) with seas increasing 4-5 ft Saturday night. A cold front moves through early Monday morning with winds out of the north/northeast with gale conditions (BF 8) and seas in excess of 11-16 ft in the offshore waters with conditions improving by Tuesday morning.

Fire Weather
Issued at 142am CDT Fri Mar 13 2026

Afternoon RH values will drop to as low as 15-20% across the Brush Country, while along the coast, a return of onshore flow will keep RH values from dropping below 30%. With weaker winds today, the fire risk will remain elevated. Onshore flow will continue gradually increase surface moisture leading to Min RH's Saturday to remain above 25% across South Texas. A hot afternoon Sunday will keep RH's in the 15-20% range with 10-15 mph sustained southerly winds creeping the fire risk higher. The next big change will be late Sunday night's cold front passage, with 20-25 mph northerly winds and RH values dropping to as low as 10%, leading to critical fire conditions.
