South Texas is bracing for a dramatic weather shift, with temperatures expected to soar to record-breaking levels on Sunday before plummeting sharply. A Red Flag Warning is in effect through Monday evening due to high fire danger.
Dramatic Temperature Swing
After morning clouds, temperatures will climb into the mid-90s on Sunday, potentially breaking a record that has stood since 1908. This warmth will be short-lived, however, as a strong cold front arrives between 5 and 7 pm Sunday evening.
The cold front will bring gusty north winds of 40-50 mph through the evening and overnight. Whereas widespread power outages are not anticipated, the winds could cause spotty outages due to falling tree limbs.
Monday and Beyond
Monday will see a significant drop in temperatures, with a low near 40° in San Antonio. Wind chill will make it sense even colder, in the 20s and 30s. Highs on Monday will struggle to reach the 50s. Tuesday morning will bring temperatures in the 30s, with a potential light freeze in the Hill Country, while San Antonio is expected to remain above freezing.
The extended forecast indicates no rain is expected for the next 7 to 10 days.
