San Antonians can expect a varied week of weather ahead, with temperatures hovering in the high 70s to low 90s, as per the latest forecast. According to the National Weather Service, today will bring a transition from mostly cloudy to sunny skies, reaching a high near 91 degrees, with light winds picking up from the south-southeast in the morning.

As evening draws in, locals should keep an eye out for potential thunderstorms with a 40 percent chance of precipitation—San Antonio's weather seems to tinker on the edge of unpredictability, refreshing moments of sun succumbing to the suspense of rainstorms, mainly expected between 10 pm and 1 am. Winds will continue from the southeast, making conditions mild with a low teetering around 70 degrees.

Tomorrow's forecast calls for significant showers and thunderstorms after 1 pm, with a 70 percent chance leading to new rainfall amounts between a tenth and a quarter of an inch; however, this could increase in areas caught under thunderstorms. The emerging gusts could reach as high as 20 mph, sparring from the south-southeast, and the barometer of temperatures will drop slightly with a high near 87 degrees.

Leading into the weekend, tomorrow night remains unsettled with showers and thunderstorms likely before 10 pm, followed by possible persistent rainfall between 10 pm and 1 am and then once again chances of showers and thunderstorms after 1 am—paths of water vacillating through the expected clouds, with a low around 66 degrees while the new breeze shifts coming from the northeast. The likelihood of precipitation holds steady at 60 percent.

Saturday brings a slight reprieve from the storms with only a 30 percent chance of isolated weather episodes after 1 pm, and temperatures dipping to a more comfortable high near 78 amidst partially sunny skies. The night continues to bear a light possibility of rain, particularly before 7 pm, then giving way to a partly cloudy evening and a lower night temperature around 62 degrees.

On Sunday, there's a slight uptick in potential thunderstorm activity post-noontime at 20 percent, keeping skies partially sunny and temperatures consistent with Saturday's high near 78. Looking ahead, the pattern of scattered showers and thunderstorms stretches into the early week, with chances lingering around the 40 to 50 percent mark through Wednesday, matched with mostly cloudy conditions and daytime highs peaking at the lower 80s.
