Snow is forecast for Chicago and Indianapolis on Sunday, and the high temperature may not climb much higher than single digits in either city.
There's no chance of that in Miami, but forecasters say there's perhaps a 50 percent chance of rain falling on the Super Bowl — something that's never happened before.
The field at Dolphin Stadium can easily withstand a shower; a drainage system under the turf can process up to three inches of rain per hour.
"The last game, we played in snow, sleet, rain. That's Chicago Bears weather," Bears coach Lovie Smith said. Plain, old rain won't bother his team, he said.
Indianapolis coach Tony Dungy said his team packed longer cleats and rain gear, just in case.
"We take pride in being able to go on the road," Dungy said. "Whatever the weather is, I don't think it will really be a major factor."
