FLAGSTAFF, Ariz. – Thin ice glimmers on rooftops this morning as cool mountain air settles into the pines. The stillness won’t last long — a breezier pattern builds through Tuesday, bringing warmer afternoons but sharper gusts across the high country. Travelers on I-40 and I-17 should plan for occasional crosswinds and blowing leaves on open stretches.
According to the National Weather Service in Flagstaff, Sunday starts clear with highs climbing into the low 70s under bright skies. Winds stay light today but strengthen by Monday afternoon as a dry front approaches from the west. Gusts may reach 25 mph Monday and Tuesday, especially in exposed areas from Williams to Winslow. Patchy smoke from prescribed burns could linger at times in lower valleys but should mix out by midday.
Despite the warming afternoons, nights remain cold — dipping into the low 30s with light frost possible in shaded valleys. By Tuesday, highs cool slightly into the mid-60s as drier, gusty air takes hold. The rest of the week looks calm and sunny, ideal for outdoor cleanup, fall hiking, and early holiday decorating before stronger November storms arrive later in the month.
Meteorologists note that La Niña remains active across the Pacific, a pattern that often favors windy, dry Novembers in northern Arizona before deeper cold fronts and snow systems arrive closer to Thanksgiving. For now, no precipitation is expected through Friday, but longer-range models hint at the season’s first winter-like system developing near mid-month.
