The derecho-producing bow echo system, racing east southeastward at a speed of nearly 100 kph (62 mph), entered the Temiscamingue region of Quebec (QC) by late Sunday evening on July 4th (Fig 4). A gust of 100 kph (62 mph) was measured at Temiscaming, and a gust of 105 kph (65 mph) was measured at Angliers, with electrical power outages occurring in the region. There also was a tremendous amount of cloud-to-ground lightning associated with the bow echo thunderstorms, with up to 6000 strikes per hour
