Arizona – Cold mountain air cuts across Flagstaff this morning, rattling bare branches and stiffening fingers within seconds. The ground feels solid underfoot, but change is already lining up. Clouds thicken fast, and winter weather is preparing to reclaim the high country as the year closes.
According to the National Weather Service in Flagstaff, early temperatures sit in the mid-30s with wind chills closer to freezing. Conditions stay mostly dry early, but shower chances increase later, with precipitation likely by New Year’s Day 2026. Snow is favored during colder periods, especially after sunset.
Across northern Arizona, today offers a brief calm window. Highs reach the upper 40s, but gusty east winds may develop at times. That warmth fades quickly as moisture arrives. By Wednesday night, rain and snow showers become more widespread, with precipitation chances climbing above 80 percent.
In Flagstaff, New Year’s Day looks unsettled. Snow showers are likely, with highs near the upper 40s and gusty southwest winds. Even light snow can create slick conditions on untreated roads. As temperatures dip toward freezing after dark, slushy patches may refreeze quickly.
Drivers on I-40, I-17, and Highway 89 should plan for changing road conditions. Slow down in snow showers. Watch for reduced visibility and slick curves. Allow extra travel time, especially during evening plans.
Shower chances linger into Thursday night, with rain or snow continuing at times. Conditions gradually improve by Friday, though cold nights remain. As the first weekend of 2026 arrives, winter stays close in the high terrain.
If you’re traveling for New Year’s celebrations, keep winter gear handy and check road updates before heading out. Seeing snow or slick spots where you are? Share what conditions look like in your neighborhood.
