PHOENIX, Ariz. – Triple-digit heat is gripping central Arizona this week, with temperatures climbing toward dangerous levels just ahead of Labor Day weekend. Drivers and outdoor workers should brace for sweltering afternoons, while families planning holiday travel may face added risks on I-10 and other busy highways.
According to the National Weather Service in Phoenix, temperatures will rise from 100°F Wednesday to 103°F Thursday, then surge past 105°F Friday through Sunday. Forecasters warn that the hottest stretch arrives this weekend, when highs may reach 107°F in Phoenix. Overnight lows will hover near 85°F, offering little relief.
The prolonged heat will create health hazards for children, seniors, and anyone without reliable air conditioning. Officials urge residents to stay hydrated, limit outdoor work to early morning, and check on vulnerable neighbors. On highways like I-10, vehicle breakdowns remain a concern, especially during peak afternoon traffic.
Thursday and Friday bring mostly sunny skies with light afternoon breezes, but heat stress will outweigh any comfort. By Saturday, temperatures climb to 106°F under unrelenting sunshine. Sunday stays equally oppressive, raising concerns for Labor Day gatherings and outdoor events across Maricopa County.
Labor Day itself may bring minor relief with a slight storm chance in the afternoon, though temperatures will still approach 108°F. Early next week, scattered thunderstorms could break the heat in some neighborhoods, but triple digits remain likely through Tuesday.
Warnings remain in place through the weekend, and further advisories are possible if storms develop Monday or Tuesday.
