I hate to say it, but inversion season is back!
High pressure building this week will block any storms from moving through. At the same time, it's going to warm up faster over the higher terrain than in lower valleys. When colder air is trapped by a layer of warmer air above it's called an inversion.
As pollution builds in the colder valleys, air quality will decline & valley haze will increase. A weak weather system brushing by later this week could bring some improvement.
