By now, everyone in Washington knows what to expect when a major snowstorm arrives: Most museums and major attractions will close. Restaurants and bars will attempt to make the most of your snow day with food and drink specials. There will be a snowball fight in Dupont Circle. on the National Mall (Update: Now in Ballston, too!)

We'll be keeping track of what you can and cannot do with your yet another D.C. snow day. Word of warning: Even if a bar says it will be open, it's worth calling before you head out. During last month's storms, some restaurants and bars initially announced that they'd open despite the weather, only to change their decision after icy conditions made it difficult for employees to get to and from work. (This time may be even trickier, due to Metro's decision to suspend bus service on Monday.)
