San Antonio started Friday, Feb. 20, under a blanket of haze and fog, with temperatures hovering around 68°F and muggy air cutting visibility in low-lying neighborhoods. A Dense Fog Advisory is in place for parts of South Central Texas through the morning, with forecasters expecting highs to climb into the mid-70s by Friday afternoon, according to the National Weather Service.
Foggy Morning Commute
The National Weather Service has a Dense Fog Advisory in effect through 9 a.m. CST Friday, Feb. 20, 2026, as patchy to locally dense fog threatens to slow the morning commute. Visibility could drop quickly in spots, especially where the fog pools in low areas.
Drivers are urged to flip on low-beam headlights, ease off the gas, and leave plenty of stopping distance, since bridges and river valleys are most likely to see the worst conditions. In short, this is not the morning to tailgate your way down the highway.
Front Brings Saturday Wind And Fire Weather Concerns
A Pacific cold front is expected to push through late Friday night into early Saturday, Feb. 21, ushering in much drier air and gusty north winds that could reach about 25 mph. The quick shift will drop Saturday night lows into the mid-40s, with temperatures around 44°F on Saturday night, Feb. 21.
Forecasters are warning of near-critical to possibly critical fire-weather conditions across much of South Central Texas on Sunday, Feb. 22, 2026, especially along and east of I-35, according to MySanAntonio. With dry air and wind teaming up, even a small spark could cause trouble.
Plan For Commutes And Outdoor Plans
Anyone hitting the road before 9 a.m. Friday, Feb. 20, 2026, should plan for extra travel time and be ready for slower speeds on surface streets as the fog lingers. Treat the reduced visibility like a serious hazard, not just a morning nuisance.
Before Saturday, Feb. 21, residents should secure loose outdoor items ahead of the stronger winds and avoid any outdoor burning while humidity dips and winds gust. Under those conditions, small flames can spread quickly.
Temperatures are expected to rebound by midweek, with highs returning to the 80s by Wednesday and Thursday, Feb. 25–26, 2026.
