Low pressure systems keep passing to the north and creating wind events with lower temperatures. There might be a possibility of precipitation if a cold front strengths and dips into our state over the weekend. Fingers crossed for some rain.
Forecast Discussion: Mostly sunny skies will continue through the middle of the week, even with yet another spring-time disturbance expected to clip Arizona late Tuesday into Wednesday. This system will cool temperatures about 10 degrees, into the middle 80s by Wednesday. It will be dry. However, we do no anticipate any significant dust. Thus, PM10 levels may edge closer to the Moderate range Tuesday, but ultimately should resume good levels Wednesday. Ozone concentrations will move higher through Tuesday ahead of the system, aided by some import from the west. Levels, however, should climb no higher than the middle Moderate range on Tuesday. Conditions overall improve Wednesday afternoon through Friday. Then there is a much colder system waiting to possibly bring rain to our forecast areas on Saturday.
