 A fast-moving wildfire is forcing thousands to evacuate in Northern California. And Pierce Kirk Sigler reports much of the region is experiencing extreme heat that's expected to stretch into next week. The Thompson Fire ignited in dry brushland in the Sierra Nevada foothills and is burning in a part of the state that's been ravaged by fires in recent years, including California's worst ever wildfire, the Camp Fire in nearby Paradise in 2018. Cal Fire says four firefighters have been injured in the Thompson Fire.
