FORECAST

Big changes have begun- a cold front is quickly dropping temperatures this evening, so have a jacket ready.

🧥JACKETS THURSDAY MORNING🧥

Gusty north winds have arrived, sending colder air into South Central Texas and likely causing wind chills in the 20s-30s tomorrow morning. Actual air temperatures will likely bottom out in the upper-30s in San Antonio and even colder in The Hill Country where a brief light freeze is expected.

🥶COLD THURSDAY🥶

As clouds increase during the day, temperatures will struggle to climb out of the 40s. Gusty winds will also add to the ‘winter feel’, so have a jacket within reach all day.

💘VALENTINE’S DAY TRENDING COLDER💘

Cloud cover is likely to be stubborn on Friday, keeping things chilly for Valentine’s Day. Once again, we probably won’t get out of the 40s. By Friday night, an increase in humidity may start to push temperatures up a bit. But, that’ll also lead to some fog and drizzle by Saturday morning.

🎢ANOTHER FRONT, MORE UPS AND DOWNS THIS WEEKEND🎢

Most of Saturday will be sunny and warm (mid 70s), but it’s important to note that Saturday morning will be foggy and damp. Very similar to today, a cold front will slide through Saturday evening, bringing cooler weather and gusty winds. Highs on Sunday are forecast to only reach the mid-50s.
