San Antonio, Texas – Showers and thunderstorms will linger through Sunday in San Antonio, but drier, hotter weather is on the way. Sunshine takes over Monday, September 8, bringing a stretch of warm afternoons in the 90s through the rest of the week.
According to the National Weather Service, Sunday carries a 40 percent chance of thunderstorms with highs near 88. A stray storm may persist into Sunday night before clearing skies arrive by Monday. Highs Monday will reach 91, followed by 94 on Tuesday and 95 on Wednesday. By late week, highs will hover near 96, leaving little relief from the early fall heat.
Travelers on I-35, I-10, and Loop 410 should prepare for wet pavement and slowdowns Sunday evening, but commutes will improve dramatically beginning Monday. While the dry pattern benefits road conditions, it will increase heat stress across Bexar County as temperatures climb.
NOAA’s extended outlook keeps much of Texas in a below-normal rainfall zone, suggesting the region could see a prolonged period of dryness. That raises concerns for local vegetation and wildfire danger as humidity drops.
The National Weather Service expects hot, sunny afternoons to dominate through next weekend, with no measurable rain in sight after Sunday.
