Arizona – Clear skies and mild air greet the desert early as winter arrives quietly, without a chill. Porch lights glow under calm conditions, and the morning feels more like October than late December across the Valley.
According to the National Weather Service in Phoenix, temperatures start in the low 50s and climb quickly, reaching near 80 this afternoon under full sunshine. Winds remain light, making for smooth travel across I-10, Loop 202, and surface streets through the day. It’s an easy start for commuters and travelers alike.
The warmth holds into Monday as clouds gradually increase. Highs again reach around 80, still well above seasonal levels. Even with added cloud cover, conditions stay dry and stable, a welcome window for errands and regional travel.
Attention turns to Tuesday. Moisture increases, and clouds thicken as a weak system approaches. Highs ease slightly into the upper 70s. While much of the day stays dry, a rain chance develops later, signaling a subtle winter shift. Roads could turn slick during any showers, especially after sunset when holiday traffic begins to pick up.
By Wednesday, shower chances continue, mainly after late morning. Rain amounts look light, but even brief showers can affect visibility and braking on busy corridors. Travelers heading out for Christmas should plan extra time and watch changing conditions, especially during evening drives.
Christmas Day itself keeps a low-end rain chance with highs in the mid-70s. No cold snap, frost, or freeze is expected in the metro, though higher terrain north and east of Phoenix could see cooler, unsettled conditions.
Enjoy the warmth, but stay weather-aware as midweek approaches. Winter may feel gentle now, yet it’s starting to show hints of change. Seeing clouds build where you are today?
