Sounds like the Metro issued is covered :) so I'll address the snow. There's a better chance than not of it snowing. So...bring warm clothes! If you're going to be out for a greater part of the day, consider getting some Under Armour (or similar) for under your clothes. Temps in the 30's are what I'd plan for. Water proof shoes are nice too if it's slushy and nasty out. Hope it snows for you! There's nothing better than seeing everything all clean and glittery with fresh snow.
