All of a sudden, Mother Nature figured out how to run a proper winter across the United States.

By next Monday, a major Arctic blast will descend the Rockies into Texas.

Temperatures 45°F below normal in Denver put actual lows close to -30°F

I'd expect this to moderate as we approach next weekend.

Unfortunately, this is a "double load" of Arctic air, as another massive chunk of cold air could wipe out the rest of Lower 48 east of the Rockies into weekend of Jan 25-26th.

Hopefully someone will turn a dial or push a button to keep this on the other side of the North Pole.
