Ozone levels improved quite a bit yesterday, dropping into the Good AQI category. As for PM10 and PM2.5, they also ended up in the Good range.
Looking ahead at ozone, we are forecasting concentrations to hover around the lower Moderate range the next couple days as troughing continues over the west coast. Beginning Sunday, we are forecasting ozone levels to trend back up as a ridge strengthens back over the region. As for particulates, we expect stable soils from recent rains to keep concentrations relatively low. We are forecasting PM10 and PM2.5 to stay in the Good AQI category through the forecast period.
