Arizona starts the morning under a clear desert sky as cool air lingers over the Valley. Porch lights glow, palm fronds barely move, and the air feels crisp but comfortable. It is a quiet start before another warm December day takes over Phoenix.
Early temperatures sit in the mid-50s, quickly climbing after sunrise. Skies stay sunny through the day, with highs reaching the upper 70s. Winds remain light, keeping driving conditions smooth across I-10, Loop 101, and surface streets. It is an ideal morning for travel or outdoor errands.
According to National Weather Service data, the warm trend continues into Sunday and Monday. Highs push close to 80 degrees, well above typical December levels. Overnight lows settle in the low to mid-50s, offering mild evenings for holiday events.
Clouds increase late Monday into Tuesday. While much of the day stays dry, moisture begins creeping north. By Tuesday night, a slight chance of showers appears, especially after sunset. Roads could turn briefly slick, particularly during evening commutes.
By Wednesday, rain chances grow. Showers may develop during the day, with a better chance into the evening. Totals look light for now, but wet pavement can still slow traffic. Drivers should allow extra time and check headlights and wipers ahead of travel.
For Christmas travel week, Phoenix avoids winter cold and snow, but rain remains the main concern. The pattern suggests off-and-on shower chances rather than steady rainfall. Flights and highways should remain mostly manageable, though brief delays are possible during heavier showers.
Enjoy the sunshine while it lasts. Keep an umbrella handy by midweek, and stay alert for changing road conditions.
