The episode as NWS BOU wrote it up.
Strong chinook winds developed in and near the Front Range Foothills. Several trees and power lines were downed in Boulder causing damage and triggering scattered electrical outages. The combination of strong winds, very dry conditions and downed power lines sparked two large wildfires. The Overland Wildfire in Boulder County near Jamestown, consumed nearly 3,900 acres and destroyed 12 structures including homes, trailers and outbuildings. Preliminary damage estimates for the value of lost property was approximately $979,000. In Douglas County, the Cherokee Ranch Wildfire consumed 1200 acres and destroyed 4 structures. Peak wind reports included: 80 mph (70 kts) in Boulder, 71 mph (62 kts) at Livermore and 63 mph (54 kts) at Pinewood Lake.
