Early Sunday, March 29, San Antonio rolled out of bed to mostly cloudy skies and that classic cool, muggy air, with Kelly Field (KSKF) clocking in at about 55°F before sunrise. A low ceiling of clouds and pockets of patchy fog are expected mainly south and west of town this morning, which could slow down the earliest commuters. As the morning wears on, the cloud deck should thin, setting the stage for a fast warmup into the afternoon.
Foggy Start, Bright Finish
Today’s high should land near 85°F, with south-southeast winds generally between 0 and 10 mph. Tonight, skies turn partly cloudy with a low around 64°F, and those SSE winds could gust up to about 20 mph. Morning fog will favor low-lying neighborhoods and areas along the San Antonio River until the sun takes over. There are no watches or warnings posted for the metro this morning, according to NWS Austin/San Antonio.
Heat Prep Starts Now
Temperatures climb quickly as the week gets going, so anyone working or playing outside will want to pace themselves. The City of San Antonio maintains a list of cooling resources and heat-safety guidance for vulnerable residents if you need an air-conditioned spot or a little extra help.
Early-Week Sizzle, Then a Shot at Storms
Highs are expected to reach the upper 80s on Monday and push into the low 90s Tuesday and Wednesday. South-southeast gusts could hit about 25 mph, which will make afternoons feel even hotter than the thermometer suggests. A shift in the weather pattern brings a slight chance of showers and isolated thunderstorms from Wednesday night into Thursday, with limited coverage but just enough to potentially interfere with some evening plans, according to NWS Austin/San Antonio.
Morning commuters should give themselves extra time in areas where fog hangs on and keep low-beam headlights on. Tie down or bring in lightweight outdoor furniture ahead of gusty afternoons, and keep water handy if you will be outside as the heat builds. Later in the week, a quick check of the radar and local alerts before heading out for evening events would not be a bad idea.
