San Antonio residents should be prepared for an erratic mix of weather as we step into September, with the National Weather Service predicting a series of showers and thunderstorms intermittently rolling through the area. The grip of summer heat remains in the forecast, with today's temperature expected to reach a high near 94 degrees. This heat comes with "heat index values as high as 101," according to detailed projections on the NWS website. But the real story might be the looming chance of precipitation that's set to dampen plans—and possibly spirits.
As we look towards this evening, there's a 30 percent chance of witness showers and thunderstorms before the clock strikes midnight, with the possibility of the light show returning after 4 a.m. Labor Day follows a similar pattern, expect more clouds than sun and a 70 percent probability of rain after 1 p.m. These pop-up storms are not mere drizzles, as noted by the NWS, "New rainfall amounts between a tenth and quarter of an inch, except higher amounts possible in thunderstorms," marking a wet end to what's been a generally parched season.
The workweek begins with more showers and possible thunderstorms continuing through Tuesday night. While there may be brief breaks from the rain, avoiding the wet weather might be difficult due to the unpredictable nature of September's skies. There's a 40 percent chance of rain on Tuesday night, with the stormy weather possibly calming down before picking up again on Wednesday.
Midweek spells more uncertainty. Wednesday presents itself with a 30 percent chance of showers and thunderstorms, particularly post-noon. By nightfall, the weather is predicted to clear up, giving way to partly cloudy skies and a rest from the rain—short-lived as it may be, with the pattern set to repeat Thursday and into the end of the week. The lingering vibe of summer starts to make herself scarce as the days progress, but not without a final nod to the heat that characterized much of August.
Toward the end of the week, temperatures are expected to rise, reaching the low 90s during the day and dipping into the mid-70s at night. Friday and Saturday in San Antonio should bring mostly sunny skies and clear nights, offering a hopeful outlook for drier and brighter weather. However, in a city where the weather is unpredictable, sunny skies may not last for long.
