Storms Thursday will hit parts of Texas, what about San Antonio?

It’s been a dry August all across the Lone Star State, courtesy of high atmospheric pressure that has lingered across the region. Through the first 12 days of the month, several cities — including San Antonio, Austin and Dallas — have not recorded any measurable rainfall.

High pressure is expected to shift slightly to the east on Thursday, which may help to bring some Pacific moisture and subsequent rain chances into parts of the state. However, the best chances of storms are likely to stay in West Texas.

For San Antonio, hot, humid and mostly rain-free weather will likely persist. However forecast models do show a chance for a few isolated showers in South Texas by Friday. Here’s an overview of what’s ahead.

Expect mostly cloudy skies early Thursday in San Antonio, as temperatures will sit near 80 degrees through 9 a.m. By the late morning, skies will clear, and temperatures will climb into the lower 90s by noon.

By the late afternoon, temperatures across South Texas are likely to reach the upper 90s to near 100 degrees. Humidity levels will also stay elevated, resulting in heat index values between 103 and 107 degrees throughout the afternoon and early evening. Winds will be quite breezy, with some gusts likely to grow stronger than 25 mph during the evening.

Scattered showers and thunderstorms are expected to form over West Texas. The best chances will occur across the Big Bend area, the Davis Mountains, and northward to Midland, Odessa and Lubbock. A few storms could be strong, capable of strong winds and frequent lightning. However, besides West Texas, the rest of the state should stay dry.

On Friday, a small surge of moisture is expected to move northward out of the Gulf of Mexico, bringing a few scattered showers and storms across South and Southeast Texas. About a 20% to 30% chance of rain is possible in cities such as Corpus Christi, Victoria, Galveston and Houston.

Rain chances farther inland will be lower, with only a 10% chance of an isolated shower in the San Antonio metro area. However, the Alamo City is likely to see a slight increase in clouds on Friday, which may bring peak daytime temperatures down by a couple of degrees.

More heat is expected across the weekend through the weekend. On both Saturday and Sunday, high temperatures are likely to rise to around 98 to 99 degrees, with maximum heat index values near 105 degrees. Morning temps will also continue to be in the upper 70s.

The third named storm of the 2026 Atlantic hurricane season, Tropical Storm Cristobal, formed Wednesday in the central North Atlantic. This storm is expected to be short-lived, however, and will likely dissipate as it moves eastward Thursday.

The National Hurricane Center is also watching two tropical disturbances farther south in the mid-Atlantic, both of which are likely to become better organized as they move west. The westernmost disturbance has an 80% chance of developing into a named storm within the next two days, and it could affect parts of the eastern Caribbean by the weekend, possibly as Tropical Storm Dolly.
