San Antonio woke up to a gray, sticky start on Sunday, March 8, 2026, with temperatures near 59°F and humidity cranking up the muggy factor. Scattered showers and a few thunderstorms are on tap through the day, with a high close to 69°F. Expect northeast winds around 5 to 10 mph, occasionally gusting up to about 20 mph.
Morning Commute
Periods of moderate rain, mixed with brief heavy downpours, could drag out the morning drive. Where rain bands repeatedly pass over the same area, localized totals may reach a quarter to a half inch. Wet roads and gusty crosswinds will be the main headaches, so give yourself extra time if you are heading out early. Similar hazards popped up yesterday in our look at the shift from sticky sunrise to hail threat.
Midweek Outlook
The unsettled pattern hangs around into the new week, and the biggest storm punch is expected from Tuesday afternoon into early Wednesday morning (March 10–11). During that window, organized showers and thunderstorms could bring locally heavy rain and some strong to marginally severe storms. According to the National Weather Service Austin/San Antonio, this is the time frame with the highest potential for damaging wind gusts and heavier rainfall. Keep an eye on updated forecasts and make sure you have a shelter plan in place if you have outdoor plans Tuesday night.
Tips For Residents
After today’s rain backs off, patchy fog is expected tonight, with lows near 63°F and visibility dropping in spots, especially on neighborhood streets. Ahead of Tuesday’s breezier south winds, which could gust into the mid 20s mph, it is a good idea to secure loose patio furniture and umbrellas so they do not go airborne. If flooding develops in low-lying areas, avoid driving through standing water, and remember the rule: turn around, do not drown.
Once the midweek system moves on, a drier stretch should settle in. Thursday is expected to be mostly sunny with a high near 71°F, then temperatures climb into the low 80s by Friday and the upper 80s by next Saturday. Keep weather alerts on and check back for updates as the midweek storms get closer.
