Heat will build to dangerous and record-challenging levels in much of the southwestern United States toward this weekend and into early next week. Temperatures will climb well past 100 F in parts of California, Nevada, Utah, Colorado, Kansas, Texas, Oklahoma, New Mexico and Arizona with the worst days of heat likely from Saturday to Monday.

While the summer months can be unbearable in terms of heat in the Southwest, temperatures will climb to 10-20 F above average for the middle of June during the pattern. “The core of the heat will be centered on Arizona, where portions of the state, including Phoenix, could approach their highest temperature on record for any calendar day,” according to AccuWeather Senior Meteorologist Kristina Pydynowski.
