A much-needed break from heavy rain in San Antonio
After a long and dry period from December 2024 through April 2025, when San Antonio recorded just 6.18 inches (157 mm) of rain, the skies finally opened up. Between Wednesday evening and Thursday morning, an astonishing 6.37 inches (162 mm) of rain fell at San Antonio International Airport, eclipsing the previous five-month total in less than 12 hours. This sudden deluge triggered widespread flash flooding across Bexar County, causing significant disruptions.
Friday: A shift toward drier but hotter conditions
The weather is now stabilizing, and the San Antonio metro area is expected to dry out going into the weekend. On Friday morning, temperatures will begin in the mid-70s °F (around 24 °C) under cloudy skies. As clouds slowly clear through the day, daytime highs will climb to around 90 °F (32 °C) by late afternoon.
However, due to residual moisture in the soil and air, humidity levels will surge, pushing heat index values between 102 °F and 107 °F (39 °C to 42 °C) across Central and South Texas. Although actual temperatures may seem moderate, feels-like conditions will be oppressive.
There is still a slight 20% chance for pop-up showers or thunderstorms, particularly in the afternoon and evening, but any rainfall is expected to be isolated. Heavier showers remain more likely east of San Antonio, in places like Victoria, Houston, and College Station.
Saturday and Sunday: Dry skies dominate across South Texas
The weekend will bring a strengthening ridge of high pressure over West Texas and New Mexico, ushering in stable weather for most of Central and South Texas. Expect morning lows in the mid to upper 70s °F (24–26 °C) and afternoon highs near 92 °F (33 °C).
Humidity, however, will remain high, keeping heat index values around 105 °F (40 °C) both days. While most of the region will stay dry, southeasterly winds from the Gulf of Mexico could trigger a few isolated storms in the afternoons. Still, the rain chances remain low—between 10% and 20%, meaning most areas won’t see another drop.
Looking ahead: The start of next week remains dry and hot
From Monday through Wednesday, dry weather is expected to continue with afternoon highs rising into the mid to upper 90s °F (35–37 °C). Morning temperatures will hover in the mid to upper 70s °F (24–26 °C). While a few scattered showers cannot be ruled out, there’s no indication of widespread rain or flooding returning anytime soon.
South Texas residents can now look forward to a quiet weekend, with plenty of heat but only a small risk of storms—a dramatic shift from the recent flood emergency.
