San Antonio residents can anticipate a dynamic shift in weather over the coming days with temperatures soaring into the high 90s and even breaching the century mark, according to the National Weather Service. The forecast for today in San Antonio, as stated on their website, predicts a high near 93 degrees with heat index values potentially hitting 101. Residents can expect the familiar south-southeast breeze at around 10 mph, occasionally gusting up to 20 mph.

Come nightfall, clouds will roll back in, settling over the city with a low around 76 degrees. Winds will remain steady from the southeast at 10 to 15 mph, with gusts up to 25 mph. There's a 20 percent chance of showers and thunderstorms on the horizon for tomorrow. These scattered showers are not expected to bring much relief from the ongoing heat, as temperatures will likely hover near 92 degrees under partly sunny skies.

Looking ahead to the weekend, conditions seem to favor outdoor plans with mostly sunny skies. Texans would do well to plan for the heat with Thursday hitting a high near 95 and Friday promising to edge up to a scorching 97 degrees. The trend shows no sign of a cool down; in fact, Saturday promises to ratchet up the intensity with a forecasted high reaching a blistering 100 degrees.

However, the true furnace of summer appears to ignite on Sunday, with temperatures expected to peak at a sweltering 102 degrees. The heat wave is set to continue, with Monday’s high potentially reaching 101. Nights will offer little relief, with weekend lows hovering around 77 to 78 degrees, as reported by the NWS.
