Arizona – Bright sun and dry air make Flagstaff feel calm for now, but winter quietly sharpens its edge as the weekend approaches. Afternoon warmth fades quickly after sunset, and cold air pools fast across the high country. By Saturday night, breath turns visible and windshields frost over before dawn.
According to the National Weather Service, a dry and stable pattern holds through Sunday, but temperatures swing hard each day. Highs stay in the low to mid-50s through the weekend, while nighttime lows fall into the lower 20s. Clear skies allow rapid cooling, setting up repeated freeze conditions.
Across Coconino County, snow is not expected, yet winter impacts remain possible. Snowmelt from sunny afternoons can refreeze after dark, creating slick patches on untreated roads, sidewalks, and parking lots. Drivers along I-40 and Route 89 should watch shaded areas where black ice can linger into early morning.
Winds stay mostly light, though brief gusts Friday and Saturday add a biting feel, especially at elevation. Outdoor plans remain manageable with layers, but pets, pipes, and vehicles need protection during the coldest hours. Morning commuters may need extra warm-up time before hitting the road.
Meteorologists continue tracking a colder national pattern next week, with increasing precipitation chances east of Arizona. For Flagstaff, dry weather holds, but winter routines stay necessary. Plan errands for midday warmth and use caution after sunset when surfaces cool quickly.
