PHOENIX (AZFamily) — Big weather changes are coming for the weekend statewide. A storm system is still on track to move into Arizona, but the timing is shifting.

Look for partly cloudy skies, light winds and an above-average high of 86 degrees today in the Valley. On average, temperatures are in the upper 70s this time of year in Phoenix. Temperatures will also hover in the mid 80s on Thursday.

Friday brings the first weather changes with the approach of a storm moving in from the Pacific. Winds will pick up Friday across Arizona ahead of the storm, which now looks to push into California on Friday and into Arizona on Saturday and Sunday. While there is a slight chance of showers still Friday night, most of the precipitation is likely to fall between Saturday morning and Sunday afternoo
