PHOENIX -- A surge of moisture is moving into Arizona from the south, leading to higher humidity and lower temperatures.  Eventually, this moisture will lead to more widespread storm activity. 

The surge of moisture was also leading to breezy conditions across parts of the state Tuesday, with winds being out of the west and southwest.  Humidity was at about 35 percent Tuesday morning, but was expected to jump to about 60 percent by Wednesday and Thursday morning. 

Storms are possible today and tomorrow in the high country, and there's a slight chance for Valley storms, too, including a threat for blowing dust. 

By Wednesday night, storm chances increase, with a better chance for storms during Thursday, Friday and Saturday.  Strong winds and heavy rain will be the main threat. 

Temperatures will also slowly start to come down.  After Monday's near-record high of 113, look for temperatures to peak today near 107 and at just 105 tomorrow. By Thursday we're forecasting just 100 degrees for a high, with clouds and storms expected.
