Overview
- By Sunday morning, the front was pressing into the Southeast as National Weather Service freeze warnings took effect for parts of North Texas from Sunday night into Monday morning.
- Gusty northerly winds frequently reaching 30 to 40 mph are accompanying the surge, driving wind chills into the teens and 20s in some areas and creating blustery travel and outdoor conditions.
- Texas faces elevated to critical fire-weather conditions under Red Flag alerts due to very low humidity, drought-stressed fuels and strong post‑frontal winds.
- Northern and higher-elevation zones are switching from rain to snow, with winter weather advisories in the Appalachians and lake-effect snow around the Great Lakes producing localized accumulations, especially above 3,500 feet.
- Central and South Florida turn sharply colder Monday into Tuesday, with wind chills in the 20s and 30s and Miami’s Tuesday morning temperatures potentially challenging a 1913 record, before temperatures rebound to the 60s–80s by Wednesday and Thursday.
