Strong low pressure moved through the Great Lakes on November 15, 2020. As it did so, it pushed a warm front through the mid-Atlantic during the late morning and early afternoon hours, causing unseasonably warm conditions to develop. Strong mid and upper level dynamics associated with this low pressure caused linear convection to develop ahead of its associated cold front early in the day. While instability ahead of the front was very limited, the strong frontal forcing combined with extreme wind fields allowed two primary lines of convection to form and produce severe convective wind gusts as they moved east. One of these lines tracked into the eastern mid-Atlantic and towards the coast during the evening hours. It produced widespread wind gusts of around 60 mph, with a number of reports of downed trees and power lines and localized property damage across the region.
