FORECAST DISCUSSION

Thunder-free to wrap the work week, but the weekend could be a different story.

Southwesterly winds aloft scour out Monsoon moisture today. Valley floors can expect mostly sunny skies this afternoon, while a stray shower or storm may pop up in the Sky Islands. Metro Tucson peaks in the mid 90s, which is on par with early September averages.

High pressure starts to work back toward the state this weekend, guiding moisture in from the south. Isolated storms are possible Saturday, with rain chances increasing to 30% Sunday and Monday. Daytime highs reach the mid to upper 90s, with storm activity dwindling after sunset.

The spurt of storms will be short lived, as drier air invades Arizona from the Pacific next week. Mostly sunny skies prevail again as soon as Wednesday.
