The November 2020 North American storm complex was a major early-season snowstorm that impacted most of the Ohio Valley from November 30–December 2 with heavy snow, gusty winds, and near-whiteout conditions. The system originated from a weak gulf low off the coast of Texas on November 29, which began to move northeastward onto land the next day. It then began to strengthen, as well as slowing its movement down, resulting in heavy, wind-driven snow for prolonged periods of time in the Ohio Valley. It also triggered a major lake-effect snow event from December 1–2 as the system stalled over Lake Ontario, resulting in additional heavy snowfall. The storm system was also responsible for a severe thunderstorm outbreak in the Southeast and Mid-Atlantic regions, causing 22 severe thunderstorms and 5 tornadoes. In total, the system is estimated to have caused at least $100 million (2020 USD) in damages.^[1] It was unofficially named Winter Storm Dane by The Weather Channel.^[2]
