San Antonio is starting Saturday clear and cool, but the thermometer has a serious climb planned. After early-morning temperatures in the low 60s, sunny skies will push the city to about 90 degrees with no rain expected.
Sunny Weekend, Warmer Nights
The National Weather Service Austin/San Antonio office expects dry, warmer-than-normal weather to continue through the weekend. Saturday night should stay mostly clear with a low near 70, followed by a mostly sunny Sunday and a high around 92.
Winds will remain light Saturday before shifting southeast Sunday at 5 to 15 mph, with gusts reaching 25 mph. That should not disrupt most outdoor plans, though the afternoon sun will make shade and water increasingly popular amenities.
Heat Builds Into The Workweek
Monday brings partly sunny skies, a high near 92 and a 20% chance of showers or thunderstorms after 1 p.m. The bigger shift arrives Tuesday and Wednesday, when highs could reach 94 and heat indexes may climb between 100 and 108 degrees in parts of the region.
Rain chances remain limited early in the week, with isolated to scattered showers and thunderstorms possible near and east of the Interstate 35 corridor. A stronger chance for unsettled weather appears Thursday and Friday, when a front could move through and bring cooler air; Friday's high is forecast near 84.
What To Watch For
For Saturday through Wednesday, plan outdoor activities earlier or later in the day, drink plenty of water and take breaks from direct sun. There are no watches, warnings or advisories posted for the San Antonio area.
