If you’ve been itchin’ to wear your favorite ugly Christmas sweater lately, you’ve probably opted for short sleeves instead! December has been a very warm month for us so far. 🎅☀️

While the rain cleared out Saturday afternoon, we’ll see another chance of rain by Sunday. Here’s what you need to know about the rest of the weekend:


  • Skies will fill back in with clouds overnight and some isolated, light rain will be possible across parts of the Hill Country.
  • Temperatures will drop into the upper 30s and low 40s before the clouds return.
  • Wind speeds will gradually drop overnight, but it will still be windy at times with gusts up to 30-35 mph.

CPS Energy emailed the following to customers on Friday evening in anticipation of high wind gusts:

“High wind speeds can bring down power lines, damage equipment and cause outages, so our crews will be on standby throughout the weekend to restore power quickly and safely. If any outages do occur, visit our outage map at for the latest updates.

“If you see a power line down, treat it as live and DO NOT TOUCH IT. Call CPS Energy immediately at 210.353.HELP (4357). Charge cell phones and other devices in advance of potential severe weather and be ready to put personal emergency plans in action should an outage occur, especially if medical equipment is used in your home.”

Winds will gust from the north up to 40-45 mph Saturday, beginning around lunch. Be sure to secure any holiday decor! (Copyright 2021 by KSAT - All rights reserved.)


  • The day will begin with temperatures near 40°. It’ll be difficult to warm to 50° on Sunday.
  • Sunday will be mainly a gray day, as an upper-level disturbance approaches from the west. ☁️
  • That disturbance will push some scattered showers through, beginning Sunday afternoon and continuing through Sunday night. Any rain will be light.


After a chilly weekend, it will warm up pretty quickly through the middle of next week.
