Phoenix residents can expect a mix of clear skies and potential thunderstorms as the week progresses. Clouds will build on Friday, bringing a higher chance of precipitation, with thunderstorms mainly expected after 4 p.m. According to the National Weather Service, highs could reach 102 degrees, followed by a 50% chance of showers and thunderstorms before 11 p.m. The evening low will be around 83 degrees, offering little relief from the persistent heat.

The weekend forecast continues with only a slight 30 percent chance of precipitation early Saturday morning, followed by mostly sunny skies and highs near 102 degrees. By Sunday, residents can anticipate a return to full sunshine with the same high temperature and calm winds, which is expected to carry over into the early part of next week.

Temperatures will creep up as the new workweek begins, with Monday seeing a sunny high around 106 degrees. Then, there’s a steady climb with Tuesday hitting a high near 108, and Wednesday presenting a scorcher at approximately 110 degrees. The peak of the heat wave seems to be settling in by Thursday, where it’s sunny and hot with an expected high of 112. Overnight lows during this period linger in the mid-to-upper 80s, offering little relief from the scorching daytime highs. The National Weather Service also hints at possible showers and thunderstorms on Thursday, though the chance remains slim at 10 percent.
