I saw this tweet from the National Weather Service which makes this freezing rain coming sound pretty severe. The Chiefs re-sodded the field and have a heating system underneath so I am guessing they can keep the field in pretty good shape.
This is something to monitor, especially for traveling to the game and the tailgating situation. We’ll know more as we get closer to the weekend. It would be unusual for a meteorologist to be completely wrong about this (right?).
