Flagstaff, Arizona – Residents and visitors celebrating New Year’s Eve in Flagstaff should prepare for subzero temperatures tonight as midnight approaches. The National Weather Service expects temperatures to drop to 18 degrees by midnight, which is warmer than average but cold enough to require warm clothing and proper precautions.
The National Weather Service says skies are expected to be mostly clear tonight, with calm winds and active weather for outdoor events. Those planning a trip should check road conditions, as subzero temperatures could cause icy spots, especially on elevated roads.
Skies will be clear on New Year’s Day with highs near 55 degrees, providing a pleasant start to 2025. Wednesday night’s low will drop to 23 degrees under sunny skies. The extended forecast calls for mild and mostly sunny conditions through the weekend, with highs in the upper 50s and lows expected to stay in the mid-20s.
If you drive along major highways such as Interstate 40 or Highway 89, be wary of overnight frost, especially in shady areas. Residents are encouraged to insulate outdoor pipes and protect pets from the cold.
