This blog post reviews a powerful early-season cold outbreak that swept across the United States in mid-November 2025. I summarize the observed temperatures, record lows, and geographic reach from the Midwest into the deep South. I also provide expert context on why this Arctic air intrusion was notable, particularly its impact on the Southeast during Veterans Day.
Overview of the mid-November 2025 Arctic surge
The event began when a strong Arctic air mass moved into the Midwest and Plains around November 7–8. It then plunged aggressively southward on November 9.
By Veterans Day (November 11), the cold pool had settled over large parts of the Southeast. This produced some of the most anomalous low temperatures observed anywhere on Earth that day.
Where the cold hit hardest
This outbreak was remarkable not only for its intensity but for its geographic reach. Freezing conditions extended to the northern Gulf Coast and northern Florida.
30s were reported as far south as Immokalee and 40s in Miami and Fort Lauderdale. In total, meteorologists logged at least 93 daily cold records from November 9–12, concentrated largely across the Southeast.
The following list highlights notable observations and local records:
Why this early-season outbreak mattered
From a meteorological perspective, the southward displacement of such a deep Arctic air mass is significant. It brought record-setting anomalies to regions unaccustomed to early-season freezes.
Impacts were practical as well as statistical. Early freezes like this can damage late-season crops, stress energy infrastructure through sudden heating demand, and create hazards for vulnerable populations not yet prepared for sustained cold.
Expert perspective and preparedness takeaways
After three decades of studying synoptic patterns and cold-air outbreaks, I can say events like this are not unprecedented. They are noteworthy for their timing and breadth.
A few practical considerations for communities and planners:
