San Antonio is starting the stretch with another round of unsettled weather, as morning showers moved through the city today and additional scattered showers and thunderstorms remained possible through the afternoon and evening. Rain chances were expected to hold around 40% at times, with highs near 80 to 84 degrees and south winds of 7 to 14 mph.
A disturbance moving in from the west was expected to keep moisture flowing across South Texas through daybreak, and the atmosphere was still forecast to stay unstable after the morning activity weakened. That meant isolated to scattered pop-up showers and storms could redevelop later in the day, even as conditions quieted somewhat for a while. The forecast for the rest of today called for rain chances between 20 and 40% through the evening.
The setup is part of a broader active pattern over South Central Texas, where forecasters are watching storms as they move from the Texas Hill Country toward the I-35 corridor. One weather update put it this way: local storms were being tracked as a weather system moved across the region tonight. For people in San Antonio, that means the rain is not arriving as one clean event but as a series of bursts that can come and go over the course of the day.
Friday is expected to offer a short break, not a full dry-out. Forecasts call for a mix of sun and clouds with a 30 percent chance of rain, and highs should climb into the mid to upper 80s, from 84 to 88 degrees. Southeast winds are expected to run around 6 to 12 mph, keeping the air mild ahead of another round of moisture.
The bigger issue arrives Saturday, when rain chances are expected to increase again and the day has been labeled a weather alert day. More rain opportunities are also expected on Sunday and into Memorial Day Monday, with temperatures staying seasonable through the holiday period. Highs should hold in the low 80s on Saturday before edging into the upper 80s by Monday.
That leaves San Antonio with a weekend that is not shaping up as a washout, but also not as a clean stretch of holiday sunshine. Friday looks like the best opening for outdoor plans, and even then rain stays in play. By Saturday, the odds tilt back toward a more active pattern, and the city appears set to keep dealing with passing showers and storms into the holiday.
For now, the answer to the question facing anyone planning around San Antonio weather is straightforward: expect brief improvement Friday, then prepare for a wetter weekend as the active pattern continues.
