If you’re headed out this weekend, expect partly cloudy skies and warm conditions leading up to the arrival of the cold front.
COLD FRONT
A strong cold front is expected to move through San Antonio late Sunday night. Afterwards, temperatures will decrease into the the 30s & 40s Monday morning for many with a slight rain chance for some. The main story will be the winds.
The front will bring much cooler & gusty conditions. Secure loose holiday decorations Sunday before the front arrives as winds could gust up to 40 mph.

NEW YEARS
After the front moves through, colder air sticks around. Morning lows dip into the 30s for Tuesday and Wednesday, with Wednesday possibly near freezing. Not expected to be freezing for everyone, but highs will stay in the 40s and 50s—so you’ll want to bundle up if celebrating outdoors.
