San Antonio woke up to warm, sticky air on Wednesday, with mid 70s temperatures and mostly cloudy skies offering little overnight relief. The National Weather Service is calling for highs near 93°F this afternoon, and heat indices pushing into the low 100s, so it will feel several degrees hotter than what the thermometer shows. South southeast breezes will stay on the light to moderate side, and the humidity will keep nights muggy with lows in the upper 70s. Keep water close, and try to schedule outdoor plans for the cooler morning or evening hours.
Afternoon Heat And Humidity
Afternoon highs are expected to climb into the low 90s, and the combination of heat and humidity will drive up the heat index. Forecasters say it could top out around 103°F today and reach near 106°F on Thursday. That is still below official heat advisory criteria, but it is enough to make outdoor labor or long workouts risky without plenty of breaks and steady hydration, according to the National Weather Service. If you work outside, aim for shade when you can, drink water often, and keep the longest or hardest tasks away from the peak afternoon heat.
Pop Up Storms Mainly East Of I 35
Rain will be hit or miss. Isolated showers and brief thunderstorms are possible mainly along and east of the I 35 and I 37 corridors, so most neighborhoods are likely to stay dry. Any storm that does bubble up could drop a quick heavy downpour and produce gusty winds, but forecasters are not expecting widespread rain today. South southeast winds should remain light to moderate, with gusts up to 20 to 25 mph possible this evening as the breeze picks up.
Weekend Into Next Week
Rain chances start to tick up late this weekend into early next week. The best odds for more widespread showers and thunderstorms arrive Monday night into Tuesday as a front approaches the region. Forecasters say the timing is still a bit uncertain, but models generally agree on a noticeable increase in precipitation chances at the start of next week, which could finally bring some more significant and very welcome rainfall to parts of the area. Keep an eye on updates if you have outdoor plans Monday or Tuesday, and expect the warm, humid pattern to hang on until then, according to the National Weather Service.
Where To Cool Off
If you do not have reliable air conditioning, the City of San Antonio maintains an interactive list of “places to stay cool,” including libraries, senior centers, and community centers that open during heat events. You can also call 3 1 1 for help finding a nearby site. For more details, see the City’s heat resources and interactive map via the City of San Antonio. It is a good idea to shift outdoor events to the morning or evening and to check the local forecast before you head out.
