Phoenix is bracing for potentially record-breaking heat as a First Alert Weather Day continues through Monday. Friday’s high could reach 116 degrees, tying a Phoenix record set in 2020, while Saturday could climb to 117 and Sunday to 115. The National Weather Service has extended the extreme heat warning through Monday night, with little overnight relief as lows remain in the lower to mid-90s. Rain chances stay mainly in eastern and southeastern Arizona this weekend before slight chances return to the Phoenix forecast Wednesday.
