HALLOWEEN FORECAST FOR SAN ANTONIO: Warm, but stalling cool front brings at least a *chance* for rain

After 50+ days straight of no measurable rain in San Antonio, things are shaking up in the forecast just in time for the spookiest holiday of them all. Here’s what you need to know:

KEY POINTS
  • COOL FRONT: Will likely stall just north of San Antonio
  • TEMPS: Warm in San Antonio, a little cooler in the Hill Country
  • RAIN: Highest chance late Wednesday night/Thursday morning
  • TRICK-OR-TREATING: Mild and muggy, small wild card chance for a shower or storm
FORECAST:

A front approaches the area Wednesday night/Thursday morning. The big question is whether or not the front moves through. As of now, we still believe it will stall just north of San Antonio, meaning it’ll stay warm for the Alamo City. Temperatures in the Hill Country will be cooler and may struggle to get out of the 70s.

The front will likely stall across the Hill Country, allowing for slightly cooler weather in the 70s for those folks. Mid-80s around San Antonio. (Copyright 2024 by KSAT – All rights reserved.)

Regardless, it’s expected to get close enough to kick up some showers and maybe a storm or two. There’s a 40% chance for showers and storms overnight Wednesday into Thursday. Less of a chance during trick-or-treating hours, but there’s still a low possibility of a stray storm – the wild card to watch. Otherwise, it’ll be warm and muggy in the Alamo City near sunset.

Rain chances the next few days in San Antonio peak Wednesday and Thursday morning. (Copyright 2024 by KSAT – All rights reserved.)
