Arizona — Gray clouds thicken over the high country as colder air presses south, signaling a sharp midweek shift. Wet pavement today gives way to falling snow levels and a renewed winter feel by Wednesday night, especially across northern Arizona.
Meteorologists are tracking a developing winter system that brings increasing rain and snow chances starting Wednesday. Initial precipitation develops near midday, mainly south of the Mogollon Rim, with snow levels near 7,000 feet. That places early impacts close to Flagstaff’s elevation but limits early accumulation.
Conditions change quickly Wednesday night. Snow levels fall to 5,500–6,500 feet, allowing snow to mix in across Flagstaff and nearby highways. Roads may turn slushy after sunset as temperatures cool and precipitation continues.
Thursday is the bigger concern. Much colder air arrives, pushing snow levels down to 4,500–5,500 feet. That opens the door for more widespread snow across Flagstaff, Williams, and portions of I-40. The threat for heavier snowfall increases Thursday afternoon and evening as the system strengthens.
Travel impacts are expected, especially during the Thursday evening commute. Slick roads, reduced visibility, and patchy blowing snow may develop quickly. Drivers should plan extra time, slow down, and keep winter emergency supplies in vehicles.
To be fair, snowfall totals remain uncertain. However, forecasters warn amounts could increase with later updates. This pattern favors accumulating snow during peak travel hours, which raises concern for crashes and delays.
Behind the system, colder nights follow into the weekend. Refreezing becomes a concern even after snow tapers, increasing the risk of black ice during early mornings.
Winter is clearly settling back in. Stay weather-aware, monitor updates, and prepare for changing road conditions.
