Gray Skies and Desert Chills: A Quiet Sunday Forecast for the Valley

Phoenix Weather Overview: Sunday, January 25, 2026

As residents of the Valley of the Sun wake up this Sunday morning, they will find a noticeably cooler and cloudier atmosphere than earlier in the week. Following a period of unsettled weather that brought scattered showers and a dip in temperatures across the state, Sunday serves as a calm, albeit overcast, conclusion to the weekend. While the rain has largely exited the metropolitan area, the residual cloud cover and crisp winter air will remain the primary story for today’s forecast.

Morning Conditions: A Chilly Start

Early birds heading out for Sunday morning coffee or sunrise hikes will need to layer up. The morning begins with temperatures hovering in the low 40s, with some outlying areas in the West Valley seeing lows dip toward 39°F. Skies are expected to be predominantly overcast, with a heavy layer of high-altitude clouds filtering out much of the early morning sun. Winds remain light and variable, keeping the wind chill factor to a minimum, though the lack of direct sunlight will make it feel significantly cooler than the actual air temperature.

Afternoon Outlook: Peaking in the Low 60s

By the afternoon, the thick cloud cover will persist, though occasional breaks in the overcast may allow for brief periods of filtered sunshine. We are looking at a projected daytime high of 64°F, which is slightly below the seasonal average of 68°F for late January. Despite the gray skies, conditions will remain dry throughout the day. Residents can expect:

• Peak Temperature: 64°F between 2:00 PM and 4:00 PM.
• Sky Conditions: Mostly cloudy to overcast.
• Wind: Calm winds from the north at 5 to 8 mph.
• Humidity: Staying relatively low, near 25-30%.

Evening and Overnight Forecast

As the sun sets this evening, temperatures will drop quickly back into the 50s. If you have outdoor dinner plans, expect a temperature of approximately 52°F by 7:00 PM. The clouds are expected to begin thinning late tonight, which will allow for significant radiational cooling. This clearing will lead to an overnight low of 40°F, marking one of the chillier nights of the month so far.

Warnings and Travel Alerts

There are currently no active rain or wind warnings for the Phoenix metropolitan area. The chance of precipitation remains at 0% for the remainder of the day. However, travelers heading north toward the high country should remain cautious of icy patches on shaded roads following the light snow and rain showers seen in those regions earlier this weekend. For those in the Valley, it is simply a day for light jackets and enjoying the rare break from the intense Arizona sun.
