Forecast Discussion:

Today, high pressure will move over Arizona and result in mostly sunny skies and light winds for the Valley. In fact, this pattern will usher in a period of mild weather conditions: high temperatures will hover in the low 70s and winds will stay mostly light throughout the next several days. However, cloud cover will increase again Friday and over the weekend as subtropical moisture streams in over the state behind the high pressure.

Another weak low pressure wave is then forecast to dive over Arizona from the northwest late Sunday into Monday. Small rain chances enter the forecast again, and daytime winds could increase out of the west on Sunday. Higher pressure and mostly light winds follow on Monday and Tuesday.

Overall, mild weather conditions will result in stagnant mornings/evenings each day. But despite these conditions, recent rain is expected to help reduce the potential for higher dust levels. Therefore, the dust risk is Low each day through at least Tuesday.
