The winter storm that walloped the Midwest over the weekend made its way east Monday, hitting Washington, D.C., but sparing New York City. New Jersey, Tennessee, Delaware, Virginia and Mississippi were all under winter weather-spawned states of emergency. Federal offices were closed in Washington, D.C., and public schools were closed in Washington and in Philadelphia. The National Weather Service predicted the storm will bring up to 9 inches of snow to the Washington area. Southern Pennsylvania could also be slammed by 6 to 8 inches of snow, while nearly a foot was predicted to fall in parts of New Jersey. More than 2,100 flights into and out of the U.S. were cancelled by 8 a.m. ET on Monday, according to FlightAware.com.
