Over 1,000 flights to and from Chicago have been canceled after a winter storm began pounding the Midwest on Monday night and continued to dump snow on the city. The storm is expected to continue moving through the Appalachian Mountains for the rest of the week. On Monday, blizzard warnings were in effect in parts of Montana and North Dakota. Snowfall is expected to fall up to one inch per hour in some areas, and up to six inches is expected to fall in Chicago by Tuesday morning. At least 270 flights were canceled by Monday night, and 100 flights were already canceled out of O’Hare for Tuesday. The storm will move east on Wednesday, hitting the District and the Baltimore area. At least it will give the area something to think about other than the sequester.
