Discussion
To varying degrees, daily storm activity is expected to continue over southeast Arizona through Sunday. In addition, storm activity is anticipated to expand westward over the Mogollon Rim and into Yavapai County as the week progresses. Thus, the potential for outflows affecting Maricopa County will continue. It difficult to know if the outflows Wednesday through Sunday will be primarily from the north/northeast or from the south/southeast; the latter being more conducive to dense blowing dust. But, for Wednesday, it looks like a better chance of outflow from the south/southeast and thus there is a Moderate risk of a dust related exceedance. For now, the other days are projected to be Low risk but that may very well change.
