Arizona – Frost clings to windshields and breath hangs in the air as Flagstaff starts the day deep in winter mode. Temperatures sit near 19 degrees early, with clear skies and calm conditions amplifying the cold.
Roads remain mostly dry, but shaded spots and untreated surfaces may feel slick during the early commute. Drivers should use caution on I-40, U.S. 180, and neighborhood roads until the sun climbs higher.
According to the National Weather Service, temperatures rebound quickly during the day. Highs rise into the low 50s this afternoon under partly sunny skies. Light winds increase later, with occasional gusts making the air feel sharper despite the sunshine.
Tonight turns cold again. Lows drop into the upper teens, allowing refreeze on wet pavement where daytime melting occurred. This is peak season for flash freezing, especially after sunset.
Thursday brings steadier improvement. Sunshine dominates, pushing highs near 48 degrees. Winds stay light to moderate, and travel conditions remain quiet across northern Arizona.
By Friday, Flagstaff begins to feel noticeably milder. Afternoon highs approach 50 degrees, with mostly clear skies and lighter winds. Nights remain cold but less severe, easing into the mid-20s.
Saturday stands out as the warmest day in this stretch. Highs reach the mid-to-upper 50s, a sharp contrast from early-week cold. Clear skies and calm winds make outdoor plans easier, though temperatures still fall quickly after sunset.
Longer-range outlooks suggest above-normal temperatures across the Southwest into early February, with limited precipitation expected. For now, winter holds on at night, but daytime warmth continues to win ground.
