Arizona Faces Extreme Heat and Storm Threats Amid Rising Humidity Extreme heat warnings and heat advisories persist across Arizona, with temperatures expected to remain dangerously high through Friday in the Phoenix area and into Saturday in Mohave County. The National Weather Service has issued alerts for multiple regions, including West Pinal County, East Valley, Yuma County, and the Sonoran Desert National Monument, while severe storms and dust advisories have been activated in southeastern Arizona. The combination of rising humidity and storm chances has prompted officials to urge residents to take precautions as the weather system continues to evolve. The heatwave has already set records, with Phoenix tying its all-time warmest morning temperature at 97 degrees and matching a daily high of 116 degrees. Severe storms developed Monday evening in southeast Arizona, leading to blowing dust advisories for Pinal County and potential outflow boundaries that could spread dust and strong winds into Maricopa County. These storms are expected to bring isolated showers or thunderstorms to the Valley, though the primary threat remains the prolonged heat. Temperatures are projected to remain near 110 degrees in Phoenix through Thursday, with storm chances ranging from 10% to 30% daily. The National Weather Service warns that while temperatures may drop slightly below 110 degrees by Wednesday, the risk of heat-related illnesses remains high. The heat advisory in the Four Corners region will last until Tuesday evening, and extreme heat warnings will expire in southeast Arizona and central mountains by evening but continue through Friday in the Phoenix area.#national_weather_service #arizona #phoenix #american_red_cross #scottsdale_fire_department
