I've done some traveling and missed a couple of events along the border while I was gone but gained some insight on the drought while traversing the Rio Grande from Taos.
The border air quality first event that I looked at that is worth mentioning was the night-time haboob on the early morning of June 20. Below is a radar animation of reflectivity starting just before midnight. Watch the outflow boundary move northward over time. Winds were high along the boundary and caused quite a bit of dust.
