The forecast right now is for 30 degrees with light snow fall. Winds around 10-15 mph.
That's a good forecast considering this game is being played in New Jersey in February. Honestly, I hope the temperatures dip, the snow builds up, and the winds kick up to 40. Make it a shit game that everyone bitches about.
The Super Bowl is the real Grandaddy of them all for football. It should be played on a field that has perfect weather (55-75 degrees, just enough wind to cool the players off, clear skies or you know, a dome).
