Arizona — Thin mountain air bites early this morning as Flagstaff wakes under clear skies and steady northeast winds. Breath hangs visible, and wind chill cuts sharper than the thermometer suggests.
Temperatures begin in the mid-30s but feel colder due to gusts topping 20 mph. Sunshine helps this afternoon, pushing highs near the low 50s. Even so, winter remains firmly in control across northern Arizona.
Winds stay active through the day, especially along I-40 and exposed stretches of Highway 89. Drivers of high-profile vehicles should remain alert for sudden gusts, particularly by midday and early afternoon.
Tonight brings a sharper turn. Clear skies allow temperatures to fall quickly, dropping near 27 degrees by early morning. Pipes, pets, and sensitive plants need protection as freeze conditions return.
Thursday looks brighter but colder at night. Afternoon highs climb into the mid-50s under full sun. Winds ease slightly, though a light breeze lingers. After sunset, temperatures slide again, bottoming out near 26 degrees.
Friday continues the dry, sunny stretch. Highs reach the low 50s, but nighttime lows dip near 22 degrees. Any melted snow or moisture refreezes quickly, increasing black ice risk on untreated roads and parking lots.
The weekend offers little relief from cold nights. Saturday and Sunday stay sunny with highs in the mid-50s. Overnight lows remain in the low 20s, keeping freeze concerns front and center.
Longer-range outlooks for Jan. 19–23 hint at continued above-normal temperatures across the Southwest overall. For Flagstaff, that still translates to cold nights due to elevation.
Dress in layers, secure outdoor items, and plan extra time for morning travel.
