SAN ANTONIO – The weather has been a bit spooky recently with very high humidity and warm temperatures. If you’ve been getting in the Halloween spirit and hoping for cooler weather, a cold front that arrived early Wednesday will shake things up a bit as the holiday gets closer.

Here’s what you need to know:

  • WEDNESDAY AFTERNOON & EVENING: As skies clear behind the front, winds could gust up to 35 to 40 mph from the north during the day Wednesday. This will lead to elevated grassfire danger, so please avoid any kind of outdoor burning. The high should only reach the upper-70s.

  • THURSDAY: The morning low will be in the low-50s around San Antonio, with 40s in the Hill Country. It’ll be sunny with a high near 80° and still quite windy, with gusts from the north up to 30 mph possible.
  • FRIDAY: An even cooler morning with lows around San Antonio in the 40s. Sunny with less wind, and a high near 80°.
  • HALLOWEEN WEEKEND: Chilly mornings will give way to comfy, sunny afternoons. The weather should be in the 60s and 70s with low humidity as the kiddos go trick-or-treating Sunday evening.
