Changing weather at Arrowhead Stadium

The weather is setting out to be warmer than expected for the AFC Championship Game at Arrowhead Stadium.

The National Weather Service had been projecting an arctic blast in Kansas City for the Chiefs' game against the New England Patriots.

But, there's been a change in the forecast.

It won't exactly be Florida-warm, but meteorologists are now expecting it to be sunny and 30 degrees at kickoff.

That may be two degrees below freezing, but it's a significant improvement from the previously-predicted -5 degrees Fahrenheit which was said to include snow and rain.

Arrowhead Stadium fans are used to the cold, though.

Twice it has been one degree at kickoff, including a December 2016 game against Tennessee.
