Today's snow is putting a damper on some Fat Tuesday plans. The Clarendon Mardi Gras Parade on Wilson Boulevard has been postponed due to "snow and ice along the parade route," according to the Clarendon Alliance, which organizes the annual community event.

A statement on the group's Web site says "We intend to reschedule the parade as soon as possible – possibly around St. Patrick’s Day ... But we need to consult with County officials before we can announce the new date."

Meanwhile, the brass-led Mardi Gras parade from Dupont Circle to the Bayou restaurant in Foggy Bottom has been canceled, though the restaurant's afternoon and night of live music, which includes Zachary Smith and the Dixie Power Trio and the Second Line Band, will go on as scheduled.

The snow won't be an issue for Arlington's Bayou Bakery, which still plans to hold a block party on North 15th Street at North Courthouse Road. Bayou rep Meg Malloy says the tents will be heated so the weather shouldn't keep revelers from eating oysters and po' boys while knocking back Abita beers and rum punch.
