Arizona – Sharp cold bites across the high country this morning as Flagstaff wakes up under clear skies and stinging wind. Thermometers hover near 19 degrees, while gusts push wind chills close to zero, making exposed skin burn within minutes.
According to the National Weather Service in Flagstaff, northeast winds increase through the morning with gusts nearing 30 mph. Despite full sunshine, temperatures recover slowly, topping out near 35 degrees this afternoon. The dry air and strong sun may feel deceiving, but cold pavement and shaded sidewalks remain slick early.
In Flagstaff, drivers along I-40, Route 66, and Milton Road should watch for frozen patches, especially on bridges and ramps. Any moisture from overnight melting refreezes quickly after sunset. Plan extra travel time and reduce speed during the morning hours.
Tonight turns sharply colder again. Clear skies allow heat to escape fast, dropping lows near 15 degrees. Wind chills dip into the single digits, raising concerns for pets, exposed pipes, and anyone spending time outdoors late.
Sunday stays sunny but cold. Afternoon highs reach about 40 degrees, with steady breezes keeping the air feeling brisk. Sunday night temperatures fall back into the mid-teens, continuing the winter pattern across northern Arizona.
By Monday, a noticeable shift begins. Highs climb into the low 40s, then push past 50 degrees by Tuesday and Wednesday. Nights remain cold, but the trend favors milder afternoons and quieter winds.
No snow appears in the immediate outlook, though the freeze-thaw cycle becomes a daily issue. Melted frost during the day can flash-freeze after dark, increasing crash risk on untreated roads. Keep traction in mind heading into the evenings.
By late January, Flagstaff gains nearly 40 extra minutes of daylight, stretching brighter evenings across the plateau. Winter mornings still dominate, but change is slowly underway. How cold did it feel in your neighborhood this morning?
