PHOENIX, Ariz. – Triple-digit heat grips central Arizona again this week, with Tuesday topping out near 104°F in Phoenix. Residents should prepare for elevated power demand, overheated vehicles, and possible delays on I-10 and Loop 202 during afternoon commutes.
According to the National Weather Service in Phoenix, light winds will shift west Tuesday afternoon, offering little relief under blazing sun. Tuesday night brings only slight cooling, with lows staying in the lower 80s across the Valley, prolonging heat stress concerns.
Drivers should carry extra water and check cooling systems before travel, especially along I-17 northbound where breakdowns rise during high heat. Power providers expect heavy air conditioning use, and officials recommend limiting peak energy demand from 3 to 6 p.m.
Wednesday holds steady near 103°F with west-southwest breezes gusting up to 20 mph. The shift offers mild circulation but little real cooling. By Thursday, Phoenix drops to 100°F, still hot but trending toward safer daytime conditions. The real break arrives Friday, when highs slide to the upper 90s for the first time in nearly two weeks.
Residents should use shade, stay hydrated, and limit strenuous outdoor activity until late evening. Relief grows into Saturday and Sunday, though highs remain just below 100°F, keeping central Arizona warmer than seasonal averages.
Warnings for excessive heat remain possible if triple digits stretch into the weekend.
