San Antonians will be reaching for water bottles and sunblock as the city braces for a toasty week ahead, with highs flirting with the mid-90s. Starting today, there's a "20 percent chance of showers and thunderstorms after 10am," but don't let the potential for precipitation mislead you—the heat index could soar as high as 102 degrees. For those planning evening outings, expect a partly cloudy night with comfortable lows settling around 75 degrees, according to the National Weather Service.

Wind patterns consistent, gusts peaking perhaps at 20 mph will offer little relief during the day. Come Saturday, with a repeated "20 percent chance of showers and thunderstorms after 1pm," the sun will again dominate mostly, proposing high temperatures identical to today's. "Mostly sunny, with a high near 93," the forecast continues to sing the same sweaty summer tune for the weekend, as stated by the National Weather Service.

As the new week rolls in, locals can look forward to more of the same: "Mostly sunny, with a high near 94," for both Sunday and Monday. The South Southeast wind will maintain, racing at 10 to 15 mph, with gusts that could reach 25 mph, as reported by the National Weather Service.

Looking ahead to midweek, there's no major shift in pattern. Tuesday's weather holds onto the mostly sunny skies with a high nearing 94 degrees. Evening temperatures through Wednesday will provide mild nighttime lows in the mid-70s. While Thursday brings the possibility of some respite with a "20 percent chance of showers and thunderstorms," as per the National Weather Service.
