Highlights

Phoenix hit 105 degrees on Father's Day, one degree below the seasonal normal, according to FOX 10 Phoenix. The relative reprieve is short-lived: forecasters say major heat risks are returning to Arizona in the days ahead.

The National Weather Service Phoenix forecast office warns of a warming trend next week, with afternoon highs likely to approach 10 degrees above daily normals by mid-to-late week, resulting in some areas of Major HeatRisk across the lower deserts.

The timing follows a year in which Phoenix broke its record for earliest 100-degree day, reaching triple digits in March, as azfamily.com reported. The NWS has flagged elevated risks for heat-related illness among people with chronic health conditions and those without adequate cooling or hydration.

Residents and property owners in Scottsdale should monitor NWS updates as the week progresses; the agency's next advisory is expected to detail the scope of the heat event.
