PHOENIX -- Monsoon moisture is slowly returning to Arizona after a couple of hot and quiet days.  Storm chances are increasing and temperatures are forecast to decrease.

At about 8:30 a.m., the National Weather Service opted to cancel the Excessive Heat Warning that was previously issued for today. 

Thick mid- and high-level cloud cover should keep temperatures a bit cooler than yesterday's scorching 111-degree high.  Mostly cloudy skies should give way to partly cloudy skies this afternoon for a high of about 107 degrees.  An isolated shower or two is possible today and tonight and blowing dust is also a possibility. 

In addition to blowing dust, ozone could make it a little tougher to breathe.  For a second day in a row, the Valley is under an Ozone Health Watch.  This may be upgraded to a High Pollution Advisory tomorrow, according to ADEQ. 

Friday brings a 20 percent chance of showers in the Valley and by the weekend, the forecast calls for a 30 percent chance of Valley rain under mostly cloudy skies.  Somewhat cooler temperatures are expected this weekend as well, topping out near 102 degrees Saturday and 99 degrees Sunday.
