Heat Dome to Shatter Records Across West | Phoenix News

A blistering heat dome is barreling into the Western U.S., with temperatures soaring 10-15 degrees above normal and potentially shattering daily records—especially in the Rockies, where some areas could flirt with all-time highs. The extreme heat, already felt on the East Coast, is set to spread eastward into the central U.S. by early next week, with cities like Billings and Salt Lake City hitting 103-105°F and Denver potentially flirting with triple digits. This isn’t just a summer anomaly—heat waves are becoming more frequent, intense, and longer due to fossil fuel emissions, with recent research showing last week’s East Coast heat would’ve been impossible without greenhouse gases. While the heat will dry out vegetation and fuel wildfires, the dome’s stagnant air limits fire-fanning winds. However, as it shifts, moisture may bring thunderstorms and lightning—offering temporary relief but adding new fire risks. This dangerous, prolonged heat is expected to linger well into next week.
