Overview
- Houston turns sharply colder behind Friday’s front, with highs in the 50s, a Red Flag Warning Saturday for gusty, dry conditions, and a light freeze most likely Saturday night into Sunday; models also point to increasing rain chances by midweek, especially south of I-10.
- San Antonio faces critical fire weather Saturday and its first hard freeze of winter with lows near the upper 20s by sunrise Sunday, while the Hill Country runs colder for longer; ERCOT projects ample power capacity.
- North Florida wakes to frost advisories and enters a freeze watch late Sunday into Monday, with the NWS warning some locations could dip to the low 20s and urging protections for plants, pipes, pets and vulnerable people.
- A brief mix of wet snow is possible Sunday into Monday near the Florida–Georgia line, including the Tallahassee area, but any accumulation remains uncertain and appears more likely in south Georgia than in Florida.
- South Florida rebounds into the upper 70s this weekend before a stronger front Sunday night delivers a colder Monday, with morning lows in the 40s to low 50s and daytime highs struggling to reach the 60s.
