Pack the Umbrella: Light Showers and Cooler Temps Sweep into Phoenix

A Shift in the Desert Skies

After a stretch of characteristic Arizona sunshine, Phoenix residents are waking up to a noticeable change in the atmosphere this Friday, January 23, 2026. A low-pressure system moving across the region has officially ended the run of dry, mid-70s weather, bringing with it increased cloud cover and the long-awaited return of precipitation to the Valley of the Sun.

Morning: A Cloudy and Damp Start

The morning hours will see a steady increase in cloud density as moisture levels rise ahead of the approaching weather system. While the early commute may start dry, humidity levels are climbing, and patchy rain is expected to develop across the metropolitan area before noon. Temperatures will start in the low 50s, so early-morning joggers and commuters should opt for a light jacket to handle the damp chill that has settled over the desert floor.

Afternoon: Showers and Mid-60s Highs

By the afternoon, the rain chances will peak at approximately 50%, with the National Weather Service predicting light accumulations around 0.10 inches for most of the Phoenix metro area. Unlike the heavy monsoon downpours, today's rain is expected to be characterized by scattered, light showers and misty conditions. The mercury will struggle to reach a high of 66°F, marking a significant dip below the seasonal averages we have seen earlier this week. Wind speeds will remain relatively mild, generally blowing from the southeast at around 5 to 10 mph, though occasional gusts may occur near the periphery of passing showers.

Evening: Cooling Down and Lingering Moisture

As the sun sets, the rain chances will begin to taper off, though overcast skies will likely persist through the night. The evening will bring a sharper drop in temperature, with lows expected to reach the mid-to-high 40s. While no official wind or flood warnings are in place, drivers are encouraged to exercise caution on the roads, as even light rain can cause slippery conditions on high-traffic desert asphalt. Looking ahead to the weekend, this cooling trend is set to continue, making tonight a perfect time for indoor activities.
