San Antonio rolled into Wednesday, April 22, 2026, under a thick blanket of fog and mist, with temperatures sitting in the upper 60s (around 68°F) and patchy visibility in many low-lying neighborhoods. Drivers can expect slower surface traffic and reduced sightlines at smaller airports through mid-morning while the fog hangs around. Skies should stay mostly cloudy with a high near 82°F, and scattered showers along with a few thunderstorms are on the table this afternoon into early evening.
Dense Fog This Morning
The National Weather Service has issued a Special Weather Statement flagging that "a few spots may have dense fog with visibility down to 1/4 mile" and urging motorists to "leave extra space when driving in fog." More details are available from NWS Austin/San Antonio.
Afternoon Showers And Spotty Storms
As the day wears on, shower and thunderstorm chances tick up, mainly east of I-35 and across the Coastal Plains. Most locations are expected to see only light rainfall totals of less than a tenth of an inch, but a few stronger, short-lived cells could quickly drop up to around a half-inch of rain and kick up brief gusty winds. South-southeast breezes will stay on the lighter side at about 5 to 10 mph, which keeps widespread severe weather off the table for now.
If you are out and about later today, keep an umbrella handy and plan for quick bursts of heavy rain that could temporarily slow down the drive or cause minor ponding on neighborhood streets.
Warming Trend Later This Week
After today, a drier and warmer pattern settles in Thursday and into the weekend, with afternoon highs climbing into the mid to upper 80s and pushing near 90°F by Saturday and Sunday. Morning clouds may still hang around at times, but afternoons should turn partly sunny and feel noticeably warmer compared with conditions earlier in the week.
Travel Tips
In fog, stick with low-beam headlights, ease off the gas, and leave extra stopping distance. Avoid using high beams, which can reflect off the fog and make visibility worse, and do not drive with hazard lights on while you are moving. If visibility drops to the point where you cannot safely see, pull completely off the road, switch on your flashers, and wait it out until conditions improve. For straightforward safety reminders, check the Texas Department of Insurance.
