Strong heating ahead of an approaching cold front generated moderate to strong instability. Instability increased as the front neared and a large line formed ahead of the front... with numerous smaller cells forming out in front of the main line. Most severe reports were almost exclusively associated with wind damage as numerous trees and power lines were downed throughout the forecast area.  In addition, lightning struck the lodge at Mt. Abram Ski Resort and ignited a fire that heavily damaged the lodge.
