A powerful Arctic blast has swept across the majority of the US, bringing record low temperatures, widespread snow, and icy winds from the Midwest all the way to Florida. This autumn’s coldest weather yet has prompted severe cold alerts and significant travel disruptions, impacting millions across the eastern two-thirds of the country.

- Temperature Plunge: Forecasters predicted record lows in the Southeast, including all of Florida, where temperatures were near $80^{\circ}F$ ($27^{\circ}C$) just a day earlier. Wind chills in Florida could drop to the $30$s (below $0^{\circ}C$).
- Snowfall: The cold air is expected to dump heavy snow:
- The Great Lakes and Appalachians could see 4 to 8 inches ($10$ to $20$ cm).
- Specific warnings for lake-effect snow near Lake Erie.
- Hazardous travel advisories were issued for Michigan, Indiana (up to 11 inches), and Wisconsin (up to 6 inches).
- Air Travel: Flight delays, including four-hour wait times at Chicago O’Hare, were compounded by the ongoing federal budget shutdown, which has forced air traffic controllers to work unpaid, leading to staffing issues and thousands of canceled flights.
- Road Hazards: Snowy conditions led to school closures and a multi-vehicle crash, briefly shutting down westbound Interstate 40 in Tennessee. Meteorologists warned of slippery surfaces and low visibility across the Midsection.
Unusual and Local Effects
- Falling Iguanas in Florida: When temperatures dip below $40^{\circ}F$ ($4^{\circ}C$), the invasive reptiles can enter a state of suspended animation and fall from trees. They typically revive with the sun’s warmth.
- Community Shelters: Local governments from Texas to Georgia, including St. Louis, Missouri, opened heated shelters for homeless residents and those whose homes were still damaged from a tornado in May.
- End of Growing Season: Weather experts issued special guidance for gardeners, confirming the freeze warning marks the end of the growing season for the Midwest and Northeast.
- Agricultural Note: While tender crops in North Florida were being harvested quickly, South Florida’s main growing regions are expected to be spared a freeze. Cool weather, as long as it stays above freezing, may actually enhance the taste and quality of crops like strawberries and blueberries.
