Residents of San Antonio can expect to potentially break out their umbrellas later today, with the forecast indicating a 20 percent chance of showers and thunderstorms kicking in after 4 p.m. According to the National Weather Service, the city will otherwise experience mostly sunny skies, with temperatures peaking near a scorching 94 degrees. The heat index might make it feel even hotter, rising as high as 101, so staying hydrated becomes a must.

The south southeast wind will persist, blowing at 10 to 15 mph and gusting up to 25 mph. This evening, the chance for rain drops, but only slightly before 8 p.m., transitioning to a partly cloudy night with a low settling around 76 degrees. Similar windy conditions will continue to blow through the nighttime.

Looking ahead to tomorrow, San Antonio is set to see more of the same – mostly sunny weather with high temperatures hovering near 94 degrees and heat index values potentially touching 100. While breaths of southeastern wind at 5 to 15 mph, and gusts as high as 25 mph, might offer some relief, it's expected to be another day where the sun reigns supreme.

The work week begins under mostly sunny skies as well, with the mercury slated to rise once more to around 94 degrees come Monday. The south southeast breeze will keep to gently jostle at 5 to 10 mph, and occasionally more vigorously gust up to 20 mph. Monday night will cool down to a mostly clear 74 degrees with a persistent southeastern wind.

Consistency in the weather pattern appears to be the theme, as Tuesday's forecast mirrors Monday's: a high near 94 degrees under mostly sunny skies, complemented by southeast winds 5 to 10 mph. The nighttime sky will be partly cloudy with the low remaining at a comfortable 74 degrees.

Mid-week brings a repeated chance for precipitation, with Wednesday sporting a 20 percent likelihood of afternoon showers and thunderstorms after 1 p.m. Despite potential rain, the day will largely be mostly sunny, with a high near 93 degrees and a southeastern wind at an easy 5 to 10 mph pace. The nighttime forecast calls for partly cloudy conditions with lows hovering around 74 degrees.

As the week progresses, Thursday's weather pattern continues undisturbed, with a 20 percent chance of rain and thunderstorms under mostly sunny skies, and highs once again near the 93-degree mark. The evening will stay partly cloudy, with lows around 74 degrees. Then, Friday arrives with more sunshine and expectations of highs near 93, wrapping up a week that seems determined to maintain its warm, sometimes damp, but mostly sunny disposition.
