MOST ACCURATE FORECAST: Slight chance of more monsoon rain in the Valley through Thursday

PHOENIX — We are tracking moisture from Tropical Storm Juliette, out in the Pacific, now surging into southern California and western Arizona.

That will bring lots of cloud coverage and chances for rain to parts of Arizona on Thursday.

The best chances will be across western Arizona, but even the Valley has a slight chance of a few light showers in the forecast.

By Friday, drier air will move in and temperatures will continue to climb.

Phoenix will top out around 108 degrees on Saturday and Sunday, putting us just a few degrees above normal over Labor Day weekend.

By late Sunday and Monday, monsoon moisture will flow back in, bringing slight chances for storms back to the Valley.
