PHOENIX -- Our stretch of sunny, hot and dry days will continue today, with a scorching Valley high of 108 degrees this afternoon.  A few clouds are expected overnight with lows dipping to the mid 70s to mid 80s around town. 

Big changes to our weather pattern begin tomorrow.  Monsoon moisture will begin returning to our region from the south, leading to some showers across parts of Arizona tomorrow.  Rain chances are slim for the Valley Thursday, but we could see some virga.  Blowing dust could be a concern with storms that could form to our south and push dust toward the Valley.  Temperatures will also be a handful of degrees cooler tomorrow with highs that are near-normal.

On Friday, more moisture moves in and Valley rain chances increase, especially Friday afternoon and evening.  Late Friday and Saturday, Tropical Storm Norbert is expected to push a surge of moisture toward Arizona, adding to rain chances and bringing the possibility of heavy rain.
