PHOENIX — After a cool down to end the weekend, we are set to see temperatures steadily climb into the midweek. However, it will still be a chilly start to Monday, with wind chills in the single digits for parts of the high country.

In the Valley, we will wake up to morning lows in the upper 40s to lower 50s with partly cloudy skies. A mix of clouds will persist throughout the day, but highs will rebound to the lower 70s.

Winds will begin to pick up in the Valley through the late morning, by the afternoon, gusts will be in the 20 mph range. For the high country, winds could gust over 30-35 mph.

The highest wind speeds will be in western Mohave County where a Wind Advisory is in effect through Monday night. Winds gusts are expected to reach in excess of 45 mph.

We remain quiet for Tuesday and much of Wednesday. However, as we gear up to ring in the New Year, the latest data show rain moving in late evening and sticking around through at least the first day of 2026 and possibly a couple of days across other parts of the state.

There is still quite a bit of disagreement in weather models in the exact timing and how long the rain sticks around. It does look more like a rain event at this time for the high country with snow levels above 9,500-10,000 feet.

We will continue to provide updates as we get closer.
