Mid-December 2007 North American winter storms

The Mid-December 2007 North American winter storms were a series of two winter storms that affected much of central and eastern North America, from December 8 to 18, 2007. The systems affected areas from Oklahoma to Newfoundland and Labrador with freezing rain, thunderstorms, sleet, snow, damaging winds, and blizzard-like conditions in various areas. The first two storms produced copious amounts of ice across the Midwestern United States and Great Plains from December 8 to 11, knocking out power to approximately 1.5 million customers from Oklahoma north to Iowa. The second storm moved northeast, producing heavy snow across New York and New England. A third storm was responsible for a major winter storm from Kansas to the Canadian Maritimes, bringing locally record-breaking snowfalls to Ontario, an icestorm across the Appalachians, and thunderstorms and 9 tornadoes to the Southeastern United States.

The ice storms were responsible for at least 22 deaths across three states. At least 25 additional deaths were blamed on the December 15–16 Midwest and Eastern snowstorm, and its aftermath across six US States and three Canadian provinces; 1 additional death was caused by the severe weather outbreak in the Southeast.
