There is a small chance for precipitation.
Mountains/Deserts clear skies, unrestricted visibility and light winds will continue through Saturday morning.
SYNOPSIS FROM THE PHOENIX OFFICE
Relatively dry conditions today before a gradual increase in moisture over the weekend and into early next week. There is a slight chance of showers and thunderstorms starting Saturday across Arizona and Phoenix.
According to the analysis by the Phoenix office Imperial County is caught in the middle of an upper-level anticyclone with a low-level trough that will be causing moisture in Arizona and the weak mid-level trough near San Diego. The anticipated result is warm conditions with mostly sunny skies
