The National Weather Service has projected a mostly sunny day for San Antonio with temperatures cruising up to a scorching 98 degrees, paired with heat index values that could soar to as high as 103, caution is advised for those venturing outdoors. In the evening, residents can expect the mercury to modestly dip to a low around 77 degrees, with a southeast wind providing a slight reprieve at 5 to 10 mph. San Antonians should prepare for a change on Thursday, as the forecast hints at a slight chance of rain showers followed by the potential rumble of thunderstorms post 1 pm, with the day's temperature peaking near 96 degrees.

As the week progresses, the weather pattern seems to flirt with unpredictability; Friday promises a 40 percent likelihood of thunderstorms amidst partly sunny skies while the temperature is a bit shy of the mid-90s, the calm winds later give way to a gentle easterly breeze which is a welcome grace for many, the night then partly clouds over with lows steadying around 76 degrees. Heading into the weekend, the chance for rain and thunderstorms lingers during the afternoon on both Saturday and Sunday although sunshine is expected to dominate most of the day with highs in the mid-90s.

As we look toward the start of a new week, Monday's forecast doesn't stray far from this pattern, presenting a 50 percent chance of showers and thunderstorms and a high near 90 degrees. The trend continues into Tuesday, with similar conditions and a high of 89 degrees, indicating that San Antonio might be in for a spell of intermittently stormy weather which means umbrellas and raincoats might be the prudent accessories for the foreseeable future.
