It's February, sooo... probably.  It all depends on your latitude and Momma Nature.  DC had four feet of snow in 2010.  It was a balmy 45F in 2011.  Depending on the city, our best guess is that the temperatures will range from cold to holy-crap-I-can't-feel-my-face.  Fun!  For example, in Sydney Australia, you will probably need... sunscreen!
