BEND, Ore. (KTVZ) – Bluer, less smoky skies for much of the High Desert for much of the weekend could have left some folks wondering why the state Department of Environmental Quality issued yet another air quality advisory on Sunday for Central Oregon, extending through Tuesday. But by Sunday evening, as winds blew a thick wall of smoke blew east into the region, sending air quality readings plunging back down to the Hazardous and Very Unhealthy levels yet again, no one wondered any more.
