The skies above San Antonio are expected to gradually transition to full sun today, ushering in fierce heat with forecasts predicting a high near 99 degrees Fahrenheit, and a heat index soaring to 105 degrees. Residents are advised to prepare for calm winds shifting to a light southeast breeze in the afternoon, according to the National Weather Service. As temperatures climb, the heat might not just test the limits of air conditioning units but could pose serious health risks, particularly to the vulnerable and elderly populations in urban areas where concrete and steel transform cities into ovens.
Tonight, the mercury is expected to dip slightly to a low around 78, while winds veer southeast at 5 to 10 mph before swinging southwest past the stroke of midnight. For those planning weekend activities, Saturday will crank the heat up even further, inching toward a blistering 103 degrees, with a heat index potentially reaching 107. The National Weather Service cautions locals to anticipate calm winds making a modest appearance as southeast breezes by day.
Partial cloud coverage is expected to offer negligible relief on Saturday night, with low temperatures hovering around 79 degrees. For Sunday, forecasters offer a glimmer of hope for respite, predicting a 20 percent chance of showers and thunderstorms post 1 p.m. However, the majority of the day will still be mostly sunny with high temperatures teasing the scales at 98 degrees.
Into the next week, San Antonio is set to continue its sizzling performance with sunny and hot conditions dominating the scene. Highs are projected to flirt with 99 degrees on both Monday and Tuesday, chilling marginally to a recurring low around 77 overnight. The searing trend holds steady into Wednesday and Thursday, with daytime highs expected to punch up to 101 degrees under mostly clear skies, so said National Weather Service forecasts. San Antonians should take heed these coming days—hydration is key, shade is your friend, and most of all, take the heat seriously.
