Record Heat Dome Brings Life-Threatening Temperatures to the Western U.S.
A massive heat dome has shifted westward, bringing extreme and life-threatening temperatures to the Desert Southwest and other parts of the western United States. According to the FOX Forecast Center, cities like Las Vegas, Phoenix, and Death Valley are expected to experience temperatures ranging from 118°F to 120°F (47.8°C to 48.9°C). Las Vegas is currently enduring a six-day streak of temperatures exceeding 110°F (43.3°C), with the potential to extend this streak into next week. Northern regions, including Utah and the Great Basin, will also see triple-digit temperatures, while Montana is forecasted to surpass 100°F (37.8°C) again. Heat alerts are in effect across the region through Sunday, and the heat dome is expected to persist into the first half of August. Smoke from Pacific Northwest wildfires is compounding the situation, making outdoor conditions even more hazardous.
