The cold isn't the only reason it would be low scoring- if it's so wet they can't hold onto the ball or lose their footing, that would hurt.
That being said, you never really know how it's going to affect the game. Some people say it's easier to grip the ball when it's wet, but not too wet. Most say it helps the defense because teams are less likely to take chances, others say it helps the offense because the offensive players know which routes they're going to be running, so they're less likely to slip and fall.
Does Rudi stumble in the backfield or does he break through the line and the safety stumbles and he breaks a long one. Time will tell, can't wait for the game!
