It’s cold to start our Thursday. Temps are in the 30s, but with total sunshine, expect a high in the mid- to upper-60s. Less wind today, too.

FRIDAY

After another cold start, we’ll quickly warm into the 70s. However, a cold front will be moving in during the afternoon. This will allow for highs only in the 50s north of San Antonio.

Friday night will be gusty and chilly, with temperatures quickly falling into the 40s after sunset.

CHILLY SATURDAY

We’ll have clouds and breezy, chilly conditions Saturday. Temperatures will struggle to get out of the 50s!

With clearing skies Saturday night, San Antonio will likely see its first freeze of the season by sunrise Sunday. So, it’ll be best to cover or bring in your plants Saturday night. Don’t forget your precious pets, too!

SUNDAY

Sunday morning will be cold with our first freeze likely for San Antonio (Copyright 2026 by KSAT - All rights reserved.)

It’s likely we’ll start the day below freezing. Temps in the 30° to 32° range are likely for San Antonio, but a deeper freeze (25° to 30°) is possible for the Hill Country.

However, with plenty of sun, we’ll quickly warm. Temps will stay cool, however, with highs near 60°.

MONDAY - MARTIN LUTHER KING JR. DAY

Monday morning temperatures should start around 40 degrees at sunrise, but rise to near 50 for the beginning of the MLK March at 10 a.m.

Lower 60s are likely by noon, so have a jacket but be prepared to shed a layer. Lastly, it’s looking dry with some sun as our next chance of rain isn’t until Tuesday.

TUESDAY THROUGH WEDNESDAY

Exact timing is a little uncertain, but it is starting to look like we could see some rain at some point Tuesday through Wednesday.

We’ll be keeping you posted on a timeline and potential rainfall amounts!
