Clear morning skies across Phoenix on Thursday will set the stage for a warm, mostly sunny afternoon, with highs climbing into the upper 70s, near 80°F, and light southeast winds. Morning readings in the mid 50s will rise quickly by midday, making it a prime day to squeeze in outdoor plans before a more unsettled stretch later this week.
Friday: Spotty Showers Possible
A weak Pacific disturbance arrives late Friday, bringing a chance of spotty showers from mid to late morning through the afternoon. According to the National Weather Service, most Valley locations will likely see only light amounts under a tenth of an inch, but isolated cells could drop up to a quarter inch in a few spots. Clouds and brief light showers may trim daytime highs to the low 70s in the wettest areas before conditions dry out Friday evening.
Weekend: Mostly Dry and Milder
Ridging returns Saturday and Sunday, bringing dry conditions and a rebound into the mid 70s with mostly sunny skies. Expect overnight lows in the low 50s and generally light winds, a comfortable setup for outdoor errands or weekend plans. There are no watches or warnings in effect for the metro area at this time.
Early Next Week: Heavier Rain Possible
Forecast guidance points to a stronger trough arriving Monday into Tuesday with the best chance for measurable rain, particularly Monday night. Forecasters are watching for valley totals of a few tenths of an inch in many locations, roughly 0.25 to 0.5 inches, with higher amounts over the mountains and upslope areas and the potential for steadier rain that could affect commutes. If that timing holds, expect cooler daytime highs and breezier south-southwest winds during the wetter period.
How to Prepare
Keep an umbrella handy for Friday and stay alert to changing conditions if you have plans Monday night into Tuesday; anything outdoors that can be moved inside should be.
