100+°F Temperature Gradient Likely As Extreme Pre-Christmas Cold Snap Hits U.S. – DAMWeather:

Temperatures will dip into the 40s down in the Everglades, and lows on Christmas morning will even get into the lower 20s across the northern Gulf Coast. (22°F is frigid for Mobile, Alabama, y’all.)

Conditions will gradually improve and warm toward some semblance of normal during that vaporwave week between Christmas and New Year’s when existence is a simulation and nobody actually gets anything done except for eating cookies and reading best-of-2022 listicles.
