As the summer season takes hold in San Antonio, residents are preparing for a prolonged stretch of scorching heat, with temperatures approaching the mid-90s and heat indices pushing well into the triple digits. According to an extended forecast from NWS, today's sun will usher in a high of 95 degrees, with the heat index, which is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature, could make it feel as warm as 103 degrees.

The forecast suggests calm breezes shifting to east southeast around 5 mph in the afternoon, offering little respite from the heat. As night falls, temperatures will dip to a low around 77, with a light south southeast wind continuing after midnight. Despite the clear skies tonight, the week ahead is set to deliver a consistent barrage of heat, with Monday's temperatures anticipated to be even hotter – climbing to a near 96 degrees and heat index values topping at a sweltering 106.

Residents can anticipate a repetitive sequence of mostly sunny days, with highs maintaining a steady grip around the mid-90s for the remainder of the week. Evenings will offer slight alleviation, with low temperatures settling in the high 70s. However, the persistent south southeast winds, ranging from 5 to 10 mph, will do little to cool down the heated cityscape.

San Antonians should brace for these conditions to persist, as the weather shows no signs of a cooling trend. By the end of the week, the city is forecasted to hit a high near 97 on Saturday, underscoring a consistent pattern of parching heat. Residents are advised to stay hydrated, limit outdoor activity during peak heat hours, and pay attention to the needs of children, the elderly, and pets during this heat wave. For the most part, the skies will remain clear, barring occasional partly cloudy nights which, bring little in the way of cooling down the dense Texas air.
