Once again, two weather forecasts promise two very different air quality scenarios for Saturday. The first scenario would have us in the low range of Unhealthy or the upper range of Unhealthy for Sensitive Groups through the early and mid-morning hours. The second scenario would see PM2.5 levels rising quickly, likely into Very Unhealthy before the morning is over. But the weather forecasts converge for the afternoon hours, so in either case we should see some clearing in the skies in the late morning or early afternoon. Then for the remainder of the day, we should see air quality that is improved compared to the morning.
