Phoenix, Arizona – Arizona drivers and outdoor workers should brace for sweltering summer heat Thursday as Phoenix climbs to 105°F, with little overnight relief. The triple-digit surge will extend into the weekend before a chance of showers rolls in Saturday night.
According to the National Weather Service in Phoenix, Thursday will be mostly sunny with calm morning winds shifting to 5 mph from the west by afternoon. The intense heat and low humidity—near 14%—elevate risks for dehydration and heat-related illness. Residents are urged to limit outdoor activity, drink water frequently, and check cooling systems before peak afternoon hours.
Friday remains just as hot with a projected high of 105°F. Winds will shift slightly southwest around 5 mph but offer minimal relief. Saturday brings more of the same until clouds increase late and a 30% chance of showers enters the region after 11 p.m.
Looking ahead, Sunday stays warm with a high near 93°F and a 40% chance of showers by nightfall. Rain chances increase into Monday, with a 50% probability and a high near 97°F. Winds may gust up to 20 mph, posing a minor hazard to high-profile vehicles on I-10 and other regional roads.

- Thursday: Sunny and hot, 105°F

- Saturday: Mostly sunny, 102°F; 30% rain chance at night
