Dangerously cold temperatures hit St. Louis area, freezes much of midwest

We're sure you know it's pretty cold outside. But just how cold is what's surprising. And dangerous.

But hey, we're not the only ones feeling the freeze. And it could be worse.

• Indiana: A state of emergency has been declared in Northwest Indiana.
• Minnesota: The inflatable roof of Vikings stadium collapsed due to snow and wind.
• Chicago: 1,600 flights grounded in Chicago, with 75 already cancelled today.
• Wisconsin: "Blizzard conditions" in much of the state, with 4 people already dead in weather-related accidents.

The storm is headed east, and south, where it's expected to feel like 20 degrees Fahrenheit in Miami tomorrow morning.
