Arizona wakes to crisp mountain air across the high country, where breath hangs briefly and frost clings to shaded ground. In Flagstaff, the cold is sharp early, but sunlight quickly begins to soften the edges.
According to the National Weather Service, temperatures dip into the low 20s early, then rebound into the mid-50s later today. Skies remain clear, and northeast winds stay light through most of the day. Travel along I-40 and Highway 89 remains dry, though icy patches can linger on bridges and shaded roads early.
As the sun climbs, pavement warms and conditions improve rapidly. Outdoor plans feel comfortable by afternoon, though shade still carries a winter bite. After sunset, temperatures fall quickly again, dropping back into the 20s overnight.
Sunday brings a similar pattern, with another cold start followed by a slightly warmer afternoon. Highs reach the upper 50s, aided by sunshine and light southeast winds. Gusts may briefly approach 15 mph, especially across open terrain.
Clouds increase Sunday night but do not bring precipitation. Monday turns mostly sunny, with highs near 57 degrees and a light west breeze. Nights remain cold, often near or below freezing, keeping winter firmly in place despite mild afternoons.
This quiet stretch fits a broader western trend. Much of Arizona stays dry and warmer than average, while colder air dominates east of the Rockies. The contrast sharpens as February begins.
Drivers should remain alert for flash-freeze conditions after sunset, especially where snowmelt or runoff refreezes. Dress in layers and allow extra time during early commutes.
Flagstaff’s winter calm continues for now. How cold did it feel in your neighborhood this morning?
