PHOENIX -- After a weekend of wild weather, Monday was off to a calm and cool start. Morning lows dropped to the 60s across the Valley, even dipping to the upper 50s in a few spots under clear skies. 

A few showers are possible today in Northern Arizona, but the rest of the state will stay dry. Drier air moves in from the west this week, keeping skies clear and eliminating any chance for more rain.

Look for a Valley high of 89 degrees Monday under sunny skies. Overnight lows will dip again to the 60s by Tuesday morning before temperatures warm to the low 90s. We'll be back to the mid-90s by the end of the week, and upper 90s are forecast for the weekend with more sunshine. 

High pressure building to our west will shift toward Arizona late in the week, bringing warmer temperatures but continued dry weather for the weekend.

Tomorrow marks the end of the monsoon season. Since there is no rain in the Valley forecast today or tomorrow, we will likely end the season with 6.34 inches of rain, which more than doubles the Valley's average of 2.71 inches for the monsoon.
