people walking in snow (times square)*(Via LA Times) – Snow began falling in parts of the Northeast on Tuesday, the vanguard of a major storm that has already led to the cancellation of thousands of flights, an unexpected closure of some federal offices and even prompted New Jersey Gov. Chris Christie to drop plans for his inauguration party.

The storm — an unwelcome sequel to the polar vortex whose icy grip choked the Midwest and East earlier this month — is also expected to bring wind chills as nasty as 10 degrees below zero.

“A wave of low pressure is developing along a strong Arctic front currently sinking southward through the Mid-Atlantic, and this is expected to develop into a strong surface low off the coast of New England,” the National Weather Service said. “This will result in an expanding shield of moderate to locally heavy snow from the central Appalachians to southern New England, including all of the Mid-Atlantic region.
