High pressure over the western U.S. continues to dominate the weather pattern. The high has shifted farther west so that Texas is on the eastern edge of the hot air dome. Along with an upper low over the western Gulf, a decent flow of moisture is streaming into the region.

This will produce widely scattered afternoon showers and a few thunderstorms through the afternoon. Some drier air has been pushed over the area west of the Coastal Plains, so most showers will be limited to that area near the shore. Overall chance of rain in San Antonio stands at 10%.

Hot weather will continue, but stay below Heat Advisory and Excessive Heat Warning levels. Look for afternoon highs to continue near 100 degrees with the Heat Index 101-103 through late week. Morning lows fall to the middle 70s.

By the weekend, a deep trough of low pressure works into the Central Plains. This will send a weak frontal boundary into Texas.  Along with the front we’ll see a decent chance at some showers and thunderstorms Saturday and Sunday. This will drop highs to the middle 90s with lows continuing in the middle 70s.
