Arizona – Red taillights glow through pockets of fog across Flagstaff as temperatures hover in the 20s early this morning. The calm air and saturated ground create a classic high-country winter setup, with freezing fog and slick pavement greeting drivers at daybreak.
According to the National Weather Service in Flagstaff, patchy freezing fog develops early, especially in low spots and near forested areas. Temperatures start near 27 degrees, allowing moisture to freeze on roads, sidewalks, and bridges. Black ice is possible along I-40, U.S. 180, and surface streets before the sun gains strength.
Conditions improve late this morning as fog thins and skies partially clear. Highs climb into the low 50s, helping roads dry out by afternoon. Winds increase slightly, with gusts near 20 mph at times, adding a brisk feel to an otherwise mild winter day.
Sunday stays mostly sunny and cooler, with highs near 50. Travel conditions remain favorable through the daytime hours. That break does not last long. By Sunday night, clouds thicken and the first chance of rain and snow showers returns, though little accumulation is expected initially.
Monday turns more unsettled. Rain and snow showers become more likely, especially during the morning and afternoon. Highs fall into the mid-40s, and snow levels hover close to Flagstaff’s elevation. Even light snowfall could quickly create slushy or slick roads during heavier bursts.
The pattern stays active into Tuesday and Wednesday. Additional rain and snow showers develop, with colder nights dropping into the 20s. Any daytime melting may refreeze after dark, raising travel concerns for early commuters.
Winter is clearly tightening its grip as the first full week of 2026 unfolds. Drivers should plan extra time during morning hours and stay alert for changing road conditions. Seeing fog or snowflakes where you are? Share what you’re noticing around town.
