Forecast Discussion:

Air quality remains superb! General flow is northerly to northeasterly for the forecast period and breezy the next few days. An interesting weather pattern develops east of Yuma over the weekend. A Pacific trough gets better organized over the West Coast and moves inland. There is a moisture draw from the south associated with this system. Atmospheric instability supports a few stronger thunderstorms in southern and central Arizona Saturday and Sunday. The bigger story during that time though may be a fetch of gusty easterly winds (20-40 mph) stretching from Tucson to Phoenix. Tight pressure gradient between the low-pressure trough and building high-pressure amplifying northward up the Midwest states is the cause. If we weren't so wet of late, dust transport from the east could have been an issue. Good AQI values are anticipated for Yuma, however.
