Forecast in Every State: Freezing

It's expected to be freezing today … in every state. In what the Weather Channel calls an arctic surge, cold air moving south and east is behind the phenomenon. The Upper Midwest and Great Lakes may see one of the region's longest-ever sub-freezing periods in November, while Buffalo, NY, could see five feet of snow—though that's a result of "highly localized" conditions, NBC News reports. At least 17 people have died in the cold weather since Saturday. In the Midwest and Northeast, things aren't likely to warm up until this weekend; elsewhere, warmer temperatures should be on their way by Thursday. Oh, and in case you were wondering, the freezing temperatures in Hawaii are only way up high on volcanoes. (More weather stories.)
