FLAGSTAFF, Ariz. – The high-country air feels crisp and still this morning, with stars blazing over the San Francisco Peaks. Temperatures have dipped into the low 30s, frosting car windshields and reminding residents that fall’s quiet, colder side has settled in across northern Arizona.
According to the National Weather Service in Flagstaff, skies will stay clear and dry through Wednesday, with high pressure keeping conditions calm and sunny. Highs will reach the upper 60s today and stay near 60 through midweek, while lows drop into the low 30s each night. Gusts up to 20 mph could stir some afternoon dust along the I-40 and Route 66 corridors.
Early mornings will stay cold enough for patchy frost across sheltered valleys and mountain meadows. Those heading out for school or early shifts should plan for icy windshields and brisk starts before sunshine warms the region quickly by late morning. With no rain or snow expected this week, travel conditions across northern Arizona should remain excellent for mountain drives and outdoor prep ahead of Halloween.
By Thursday and Friday, temperatures will rise slightly into the upper 60s under full sunshine — ideal for outdoor events and trick-or-treat plans. Halloween evening looks crisp but comfortable, with clear skies and readings near 50 degrees at sunset.
Long-range outlooks hint that early November could bring a cooler, more unsettled turn, possibly signaling the start of Arizona’s transition toward winter weather in the high country.
