San Antonio woke up to a cloudy, muggy Wednesday on March 11, with temperatures hovering around 63°F and the sky already gearing up for a noisy start. Showers and thunderstorms are expected to roll through before about 10 a.m., then clear out for a mostly sunny afternoon with a high near 85°F. The early storms could be brief but heavy, so commuters may want to leave extra time and be ready for some localized ponding on the roads, as reported by the National Weather Service.
Morning Commute
Showers and thunderstorms are expected to hang around through the morning drive, with new rainfall totals between one-half and three-quarters of an inch and the potential for quick, heavy downpours. A few stronger cells could toss in small hail and damaging wind gusts up to 40 to 50 mph, especially east of Highway 77.
According to the National Weather Service Austin/San Antonio, the main window for the heaviest storms is before mid-morning. After that, conditions should turn mostly sunny by midday, a fast flip from stormy to springlike.
Afternoon And Tonight
By midday, skies are expected to clear out and temperatures will climb into the mid-80s as winds swing around to the west-northwest and stay breezy through the afternoon and evening. Tonight looks clear but still gusty, with north winds around 10 to 20 mph and occasional stronger gusts possible. Overnight lows will drop to around 49°F.
Local reporting from the San Antonio Express-News echoes the concern for strong storms and gusty winds during this stretch.
Weekend Outlook
Warmer, dry weather is expected to settle in from Friday into the weekend. Highs should reach the low to mid 80s on Friday, then climb into the upper 80s to near 90°F by Sunday. A stronger cold front is projected to move through Sunday night into Monday, bringing a cooler start to next week.
Forecasters are also flagging elevated fire-weather concerns Monday afternoon where relative humidity drops into the teens and northeast winds pick up. According to the National Weather Service Austin/San Antonio, residents should secure loose outdoor items ahead of the gusty conditions and avoid driving through standing water during the morning storms.
