Heat Wave Expands Across 17 States, Pushing Dozens of Record Highs

A West-to-central U.S. heat wave expands into 17 states, with forecasts for 60+ new daily records and a possible 100°F day in Phoenix; other cities such as Albuquerque, Austin, Las Vegas, Oklahoma City, Tucson and Tulsa may hit 90°F or higher as the heat shifts east toward the East Coast by Friday. Forecasters warn of dangerous fire-weather conditions due to gusty winds and very low humidity, with more record temperatures likely through the weekend.
