San Antonio is gearing up for a stretch of classic Lone Star State heat, with temperatures predicted to hover in the mid-90s throughout the week. According to National Weather Service, today will be sunny with a high near 96, accompanied by light and variable wind shifting to the east in the afternoon.

Tonight's skies will remain mostly clear, as temperatures drop to a comfortable low around 73. An east southeast wind is expected to blow at a gentle 5 to 10 mph. The forecast for tomorrow ramps up the heat just a notch with a high near 97 and northeast winds turning to east southeast in the afternoon. "Winds could gust as high as 20 mph," the forecast suggests, hinting at a breezy counter to the warm temperatures.

The weekend outlook resembles a copy-paste of summertime conditions: mostly sunny on Saturday with a high again near 96, and similar winds from the southeast at 5 to 10 mph, gusting to 20 mph at times. Saturday night will see partly cloudy skies with a low around 73, and a persistent south southeast wind moving at 5 to 15 mph with comparable gusts.

Continuing the trend, Sunday promises mostly sunny skies and yet another high of around 96 degrees. The winds will maintain its southeast dance at 5 to 10 mph with gusts paralleling previous days. Sunday Night, "Partly cloudy, with a low around 72," informs the NWS, predicting a near mirror image of Saturday's evening conditions. Monday stays the course of sunny weather, with a lesser high near 94 degrees and an east wind moving at a gentle 5 to 10 mph.

As we edge into the new week, a minor shift appears on the horizon. Tuesday introduces a 20 percent chance of showers and thunderstorms, though the sun is still expected to dominate with a high near 95. Into the night, the partly cloudy theme continues, with a low settling around 73 degrees. Wednesday echoes Tuesday's conditions with that same 20 percent chance of rain showers and thunderstorms amidst an otherwise mostly sunny day and a high near 95.
