FLAGSTAFF, Ariz. – Under a silver-blue dawn sky, the San Francisco Peaks glow faintly with a promise of another dry, crisp morning. The air feels cool and clean — the kind that nips at your fingertips while you scrape frost from the windshield. Northern Arizona is waking to a steady stretch of clear, breezy fall weather that hints at winter’s slow approach.

The National Weather Service in Flagstaff reports that highs will hold near the mid to upper 60s through Wednesday, with gusty west winds returning each afternoon. Gusts could reach 25 mph at times, especially along exposed ridges and open stretches of I-40 and Route 89. While the days will feel mild under abundant sunshine, nights continue to dip near or just below freezing, particularly across higher terrain.

Tuesday and Wednesday bring more of the same — crisp, dry air with bright skies and steady afternoon winds. Highs reach the upper 60s before sliding slightly cooler into Thursday and Friday as weak high pressure builds back in. Winds ease, but overnight lows may settle into the upper 20s to low 30s, marking the first sustained freeze of early November for parts of the plateau.

By the weekend, sunshine holds firm with highs rebounding near 67°F, making it a fine stretch for leaf cleanup, early holiday decorating, or Veterans Day travel plans across northern Arizona. No rain or snow is expected this week, but forecasters note models are hinting at a colder Pacific trough developing mid-next week — a system that could bring the season’s first flurries if temperatures continue trending downward.

For now, Flagstaff’s fall weather remains steady, dry, and unmistakably November — brisk mornings, breezy afternoons, and that slow, inevitable march toward winter’s doorstep.
