As we roll on into July, our persistent low pressure system is still hanging around the region, giving us a good chance of poor air quality. We should see rising PM2.5 levels overnight, with the air quality reaching into Very Unhealthy and possibly into Hazardous. But we should see some reduction in those pollution levels by late morning or afternoon as we see the polluted air mass we're in now shift to the southeast. There is a chance we could see some real relief as the rain moves in, but it is most likely that we will not see PM2.5 levels drop past Unhealthy or Unhealthy for Sensitive Groups.
