Forecast Discussion:
Ozone just reached the Moderate AQI category yesterday. Dry conditions have returned and will continue the next several days. The sunshine will keep daily ozone levels the next few days in the Upper Good AQI category. Starting Friday, there will be stronger northeast winds, and this could help limit ozone concentrations.
PM10 and PM2.5 were in the Good AQI range yesterday. The recent rains will help to limit how much PM10 is lofted in the coming days. The next chance for stronger winds will be Friday as they come from the northeast. This will be monitored, but overall it will begin a string of breezy days through the weekend. Daily PM10 levels are forecast to remain in the Good AQI range, and PM2.5 will have similar trends.
