FLAGSTAFF, Ariz. – The morning air bites under a 30°F chill, frost glinting on pine needles as the first light touches the San Francisco Peaks. Streets are quiet, the sky perfectly clear — a calm, cold start to November across northern Arizona. Though the morning begins brisk, plenty of sunshine will warm things quickly, setting up another string of classic high-country days.

The National Weather Service in Flagstaff expects steady conditions through Monday, with highs climbing from the upper 60s today to the low 70s by Sunday. Skies will stay clear, and winds remain light through the weekend before turning slightly breezy as the next system approaches midweek. It’s the kind of crisp fall weather that invites hiking, early holiday prep, or a drive along I-40 before cooler trends arrive later in the week.

Nighttime lows continue to dip into the upper 20s and low 30s, meaning another round of frost and light freeze potential for mountain valleys. Residents should protect sensitive plants and outdoor plumbing through the weekend.

By Tuesday, models hint at a modest pattern shift, bringing increased breezes and perhaps a few clouds. Still, Flagstaff remains dry for now, with no early snow chances in sight — though the seasonal clock is ticking, and early November is often the calm before winter’s first flakes.

After all, it’s high-country living at its best — brisk mornings, bluebird afternoons, and the unmistakable feel of winter quietly approaching.
