San Antonio rolled into Thursday under cloudy, muggy skies, with temperatures near 71°F and dew points in the mid-60s that made the morning commute feel more like a slow walk through a sauna. The heat will ramp up quickly, with mostly cloudy to partly sunny skies and an afternoon high near 90°F on tap. South-southeast breezes start off light, then pick up as the day wears on.
Afternoon Heat And A Sticky Ride Home
Through the afternoon, expect the heat to build across the city, with highs near 90°F and mid-90s farther south and west. Southerly winds around 5-10 mph will add to the warm feel, and low clouds may hang around into the evening before finally breaking up. Overnight, temperatures do not offer much relief, with lows holding in the upper 60s to near 70°F in many neighborhoods, according to the National Weather Service Austin/San Antonio.
Cold Front Crashes In Saturday With Storm Threat
A cold front moves in Saturday morning and slides east through the day, bringing a 40-50% chance of showers and scattered thunderstorms, along with pockets of locally heavy rain. Forecasters highlight a low-end excessive rainfall risk for parts of the area, meaning brief heavy downpours could cause localized ponding if storms repeatedly track over the same spots. The front flips the winds and knocks temperatures down, with highs dropping into the upper 60s to around 80°F on Saturday and much cooler readings lingering into Monday, according to the National Weather Service Austin/San Antonio.
Blustery Nights And A Cooler Stretch Ahead
Behind the front, gusty northerly winds are likely Saturday night into Sunday, with gusts reaching 25-30 mph at times. Evening plans may feel brisk and any lightweight outdoor gear could be doing more traveling than you are. Highs fall into the upper 60s on Sunday and only reach the mid-60s on Monday before a gradual warmup returns by midweek. If you are planning outdoor activities this weekend, keep rain gear handy and secure loose lawn furniture, and avoid driving through standing water if those heavier downpours show up.
