Sufficient moisture will remain in place across the area into the holiday weekend, allowing for at least a slight chance of mainly afternoon and evening showers and thunderstorms. The upper high pressure system responsible for feeding this moisture into the region will shift to our west and give a drier flow pattern to the area next week. This will push the slight chance of thunderstorms back generally to the east of the greater Phoenix area. Meanwhile , temperatures will be near or slightly above seasonal normals.
