San Antonio woke up under a blanket of clouds Thursday, April 2, 2026, with temperatures hovering around 72°F and plenty of sticky humidity to go around. A band of showers and a few thunderstorms is expected to move through between 7 a.m. and 10 a.m. CDT. Conditions should turn somewhat drier as the afternoon wears on, with highs near 86°F, although a south-southeast breeze will keep it feeling warm and muggy.
Morning Storm Chances
The best shot at showers and storms lands right on the morning commute, especially across the Hill Country and along the I‑35 corridor. Brief heavy downpours and lightning are possible as this band moves through. Forecasters are calling for roughly a 40% chance of precipitation this morning, with new rainfall amounts generally between a tenth and a quarter of an inch. There are no active watches or warnings for Bexar County at this time, according to the National Weather Service Austin/San Antonio.
Afternoon Winds Pick Up
This afternoon, southeast winds around 5 to 15 mph are expected, with gusts that could reach about 25 mph and make the evening drive feel a bit blustery. Friday will stay breezy, with gusts near 30 mph possible, so unsecured patio furniture and umbrellas could easily go airborne. Temperatures will remain well above normal through Friday, then a cold front is forecast to arrive over the weekend and shake things up.
Weekend Rain Potential
A stronger system is on track to shove a cold front through the area on Saturday, April 4, 2026. That front is expected to bring widespread showers and thunderstorms, a high chance of rain around 90%, and the potential for locally heavy rainfall as atmospheric moisture climbs above 1.5 inches. Behind the front, cooler air settles in Sunday, April 5, 2026, with highs dropping into the mid‑60s and lingering chances for showers. The NWS forecast discussion lays out more details on timing and the heavier rain threat.
Plan Ahead
If you have outdoor plans this weekend, it is a good idea to line up a dry backup and keep an eye on radar from Friday night through Saturday afternoon. Brief heavy downpours can still cause localized ponding even when widespread flooding is not expected. Secure loose outdoor items, keep umbrellas or rain jackets handy, and check updated forecasts before you head out.
