FORECAST

FRIDAY

Friday will serve as a transition day, with drier air punching in from the northwest, before a shot of colder air moves through late Friday night. Before that happens, a window for a few showers and even a storm will exist for areas mainly east of I-35. It’ll turn colder by midnight Saturday.

WEEKEND

Saturday morning will be WINDY, with gusts of 40 mph possible out of the north after sunrise. That also means Mountain Cedar levels could rise.

Additionally, those winds will combine with temperatures in the 40s to bring wind chill values into the 30s. You’ll want to dress warm for any early Saturday plans. Temps should rebound to near 60 by Saturday afternoon.

Sunday morning has the potential to bring freezing temperatures for those just to the north and west of San Antonio. At this time, we expect most inside Loop 1604 to stay above the freezing mark. That’ll also be the case for Monday morning.

Low temperatures will drop to or just below freezing for those north and west of SA. (Copyright KSAT-12 2025 – All Rights Reserved)Daily Forecast
