San Antonians can expect a series of temperamental weather conditions over the next week, with chances of showers and thunderstorms peppering the otherwise hot and sunny Texan days. As reported by the National Weather Service, the city will experience a 30 percent chance of showers and thunderstorms this afternoon, with an anticipated high of 91 degrees. Locals will feel the swelter more intensely with heat index values soaring as high as 103 degrees before heading into a milder evening.
The humidity is set to persist, with tonight's forecast showing an increased cloudiness and a 10 percent chance of precipitation before dusk. Southeast winds will continue to breeze at 5 to 10 mph into the weekend. The theme of variable cloud cover and sporadic rain chances carry over into tomorrow and Sunday, boasting high temperatures in the low to mid-90s, and sticking to the familiar pattern of gradual clearing as the day progresses.
For those planning outdoor activities, it could be wise to keep an umbrella handy—especially in the afternoons. The National Weather Service suggests a consistent rhythm of brighter mornings and potential thunderstorms striking post-lunch hour. By evening, the city is expected to settle into low temperatures in the mid-70s with gentle southeastern winds providing a slight reprieve from the day's intense heat.
As the week launches, Monday's skies will shine mostly sunny with highs hovering near 94 degrees, adhering closely to Sunday's forecast. The familiar pattern of clear skies will prevail into the night, and refreshing lows around 76 degrees might grant San Antonians a comfortable sleep. Tuesday and Wednesday mirror these sunny conditions, though thermometers could inch a couple of degrees higher, approaching the mid-90s without much wind to loosen the day's grip. Prepare for the holiday, Juneteenth, with a partial cloud cover and a 30 percent chance of rain as temperatures are predicted to take a slight dip near 90 degrees.
