Forecast Discussion:

A slight increase in clouds today as a weak and dry weather disturbance brushes through the state. This system will quickly slide east as high pressure builds back into the region tomorrow into Sunday. This pattern will result in light winds and afternoon high temperatures in the low to mid-70s.

Late Sunday into Monday, a stronger storm system will move into the state, which will once again increase clouds and breezes. Right now, forecasting, southwest winds of 5-15mph during the afternoon on Sunday before increasing to around 10-20mph out of the north-northwest Monday. This storm will also be lacking a lot of moisture, so all rain chances will stay well north and east of Phoenix.

The main concern for air quality in this forecast will once again be the light winds allowing PM-10 and PM-2.5 to rise. PM-2.5 is forecast to be in the Moderates through the forecast period. Slight improvement in air quality is expected on Sunday and Monday with the added breezes.

Have a great weekend!
