NWS Forecast Office Phoenix, AZ

A series of weather disturbances approaching from the west will act on moderate amounts of moisture to produce scattered thunderstorms today and Tuesday over south central Arizona. The stronger storms have the potential to produce moderate hail with diameters over one half inch. Gusty wind and heavy rain is also possible with stronger storms. The best threat for significant thunderstorms will be over higher terrain areas east of Phoenix, although some storms may affect the greater Phoenix area.
