San Antonio is waking up to a cloudy Friday with a high near 86°F and a slight 20% chance of showers and thunderstorms developing between 1 PM and 4 PM CT, according to the National Weather Service.

If you’re heading downtown to the River Walk or catching an event at the Frost Bank Center this weekend, here’s what to expect: the National Weather Service forecasters note that while most of today will be dry, isolated storms could become strong to marginally severe if they develop, with the main threats being large hail and damaging wind gusts. The good news? Chances remain low, and most of us will stay dry.

This morning, watch for patchy fog along the escarpment and southern Edwards Plateau during your commute—light winds could create visibility issues in isolated spots. By mid-to-late morning, clearing should begin along the Rio Grande.

Weekend Outlook: Heat Cranks Up

Saturday brings partly sunny skies and a hotter high near 91°F, with another 9% chance of isolated storms, mainly over the Hill Country and Rio Grande Plains. Heat indices will approach or exceed 100°F by Sunday and into early next week, so stay hydrated. Grab a Yeti rambler water bottle to keep drinks cold during outdoor activities.

If you’re planning to tailgate before the Spurs Rd 1 Game 5 vs. West Conf Qtrs: Trail Blazers on April 28th at Frost Bank Center, bring a pop-up canopy tent with weights—Saturday and Tuesday will be hot and humid with light winds. Consider Official team gear on Fanatics to show your silver and black pride. You can grab Get tickets on SeatGeek or Find tickets on StubHub if you’re still looking to catch the playoff action.

For those heading to Bruce Springsteen and The E Street Band’s Land of Hope & Dreams American Tour at Moody Center ATX on April 26th, expect warm evening conditions after the show—perfect for a post-concert walk around downtown. Find tickets on StubHub to secure your spot.

Perfect Grilling Weather

Today and Saturday are ideal for firing up the grill. Burgers, steaks, or grilled chicken with corn on the cob are calling your name. Grab an instant-read meat thermometer and a grill brush and scraper set to keep your grill in top shape. With heat indices climbing toward triple digits early next week, do your grilling now while conditions are pleasant.

If you’re battling spring allergies with all this pollen and changing weather, Claritin non-drowsy allergy can help you enjoy the outdoors comfortably.
