Flagstaff, Ariz. – Under a dome of clear mountain air, Flagstaff wakes to quiet streets, thin frost on rooftops, and skies so clear the sunrise seems to stretch forever. The calm won’t be fleeting — northern Arizona is in for a stretch of crisp, dry weather with classic fall vibes and just a hint of winter chill whispering through the high country.
According to the National Weather Service in Flagstaff, Thursday begins sunny and steady, with highs near 60°F and light southwest winds brushing across the San Francisco Peaks. Skies remain mostly clear into Friday, where temperatures rebound to the low 60s, offering perfect conditions for late-October travel, outdoor projects, and early Halloween setup.
But mornings will feel brisk. Lows drop to the low 30s through Saturday, cold enough to leave a touch of frost in shaded valleys and along higher ridges. Winds strengthen slightly by Sunday, with gusts up to 25 mph expected as a drier front passes to the north. The result — more sun, cool air, and that unmistakable high-country snap that makes fall in Flagstaff unforgettable.
No major storms are in sight through early next week, though long-range models are hinting at a pattern change by Halloween week that could bring the season’s first mountain snow above 9,000 feet. For now, it’s golden aspens, chilly dawns, and sweater weather — ideal for a drive along Route 66 or a hike through Lockett Meadow before the true cold sets in.
