I don't see any worry from the weather for the game. If breezy & snowing i see it more as a running game. Advantage Steelers: Defense stopping the run & Offensively Ben scrambling and buying the receivers more time to get open.
Taken from the Weather Channel:
A few snow showers. Highs in the low 30s and lows in the upper 20s. Wind SSW at 9 mph. Sunset @ 5:18 pm.
