Forecast Discussion:
High pressure will continue to dominate over the Southwest today (Friday). As a result, light winds, sunny skies, and temperatures near 100° are expected. Then come Saturday, the high pressure will begin to exit off to the east, resulting in afternoon breezes out of the southwest, and possibly a little bit of high-level cloud cover. As for PM10 (dust), PM10 will likely be elevated in the afternoon because of the winds, particularly for dust-prone areas.
Looking at Sunday and beyond, the atmosphere will be relatively active over the Southwest. Since a strong high pressure is not forecast to develop over the region, ozone levels should run relatively low. But, we can't rule out pockets of dust from afternoon breezes on Sunday and Tuesday. Lastly, highest PM10 and PM2.5 (smoke) levels will continue in the mornings, mainly tied to local activity.
Check back on Monday morning for the next West Pinal Air Quality Forecast.
