Another round of scattered showers & thunderstorms is expected to develop over the Northern AZ high terrain and Southeastern AZ this afternoon. Later in the afternoon, chances for isolated thunderstorms extend into the foothills and adjacent lower deserts of northern/northeastern Maricopa County. The main concerns with any thunderstorms that do develop will be locally strong outflow winds, some blowing or lofted dust, and more frequent lightning.
High temperatures running 4 to 8 degrees above normal will be common through the middle of this week with temperatures peaking around Tue-Wed, resulting in widespread moderate to locally major HeatRisk. Temperatures will cool closer to normal by late week. Chances for showers and thunderstorms will continue early this week, with greatest coverage expected across the lower deserts on Monday.
Afternoon high temperatures are likely to reach a 5 to 10 degree above normal through the middle of next week, which could result in some local areas of major HeatRisk. Never underestimate the heat, and plan your weekend accordingly! Remember to drink plenty of water and take breaks in air conditioning.
