Flagstaff, AZ – The air over northern Arizona feels sharp and still this morning, with frosted windshields glinting under clear skies. Temperatures in Flagstaff dipped to the mid-20s before sunrise — part of a pattern that will keep mornings freezing cold through Friday as dry high pressure lingers.
According to the National Weather Service in Flagstaff, daytime highs will hover near 61°F to 64°F this week under sunny skies. But by evening, warmth fades quickly, and temperatures plunge below 30°F. Drivers along I-40 and U.S. 89 should plan for icy conditions early each morning, especially on shaded roads and bridges where refreezing can create slick patches.
The next few days will remain calm and dry, making for perfect conditions for outdoor errands, light hiking, or early holiday decorating — but bundle up. “We’re in that late-fall stretch where the afternoons feel mild, but mornings remind you winter’s here,” one meteorologist noted.
Looking ahead, models hint at cooler air returning around December 14–16, with a small chance of snow showers brushing the San Francisco Peaks and northern Coconino County. Travelers heading north or east should monitor for potential frost advisories as the weekend approaches.
Five-Day Outlook (Flagstaff, AZ):
- Thursday: Sunny, high 64°F. Low 27°F.
- Friday: Sunny, high 62°F. Low 29°F.
- Saturday: Sunny, high 61°F. Low 30°F.
