FLAGSTAFF, Ariz. — A deep chill grips the mountain air before dawn, the pines standing still under a starlit sky as temperatures hover near 30 degrees. Frost glistens across rooftops and windshields — a quiet reminder that northern Arizona’s early winter edge has arrived.
According to the National Weather Service in Flagstaff, a stretch of dry, sunny weather continues through Friday, but nights will remain sharply cold. Afternoon highs in the mid to upper 60s will offer brief warmth before the mercury quickly drops back below freezing after sunset. Winds will stay light most of the week, though occasional gusts up to 20 mph could stir by Thursday afternoon.
Drivers along I-40 and U.S. 89 should stay alert for icy patches during the early morning hours, especially in shaded valleys and mountain passes. Residents are urged to protect outdoor pipes and sensitive plants and to bring pets inside during the coldest part of the night.
While no snow is expected through the weekend, long-range models hint at a potential pattern shift closer to Veterans Day, with colder air spilling south from the Rockies and a possible early-season snow chance for the higher peaks. For now, it’s classic late-fall weather — sunny days, crisp air, and nights cold enough to feel winter knocking.
The clear stretch will make for perfect late-fall hiking, leaf cleanup, and early holiday decorating before the next big chill sets in next week.
