Flagstaff, AZ – A sunny and warmer week is in store for northern Arizona, with temperatures climbing steadily starting Wednesday and extending through the weekend. Afternoon highs are expected to approach 73 degrees on Wednesday, with even warmer conditions forecast as the week progresses. By Saturday, several areas could experience near-record highs, particularly along major roadways such as I-40 and I-17.
According to the National Weather Service in Flagstaff, clear skies and light winds will dominate the week, creating ideal conditions for outdoor activities but also increasing the risk of heat-related issues by the weekend. Drivers along I-17 and I-40 should prepare for elevated temperatures and ensure vehicles are well-maintained, particularly for long trips.
On Thursday and Friday, temperatures will hover around the low 70s, and by the weekend, highs could reach 76 to 78 degrees. Phoenix and other lower-elevation cities are expected to see temperatures climb into the 90s, increasing the heat risks in urban areas.
Those planning to be outdoors or traveling through the region should stay hydrated, wear sunscreen, and avoid strenuous activities during peak afternoon heat. The warming trend is anticipated to last through Sunday, after which a slight cooling is forecast. Wind gusts of up to 16 mph are expected Thursday, potentially impacting driving conditions on I-40.
