Forecast Discussion:
There were a few hours yesterday with high PM2.5 concentrations, which was enough to lift PM2.5 into the Moderate AQI category. Particulate levels continue to be a little elevated this morning, but seem to be slowly returning to normal. Ozone and PM10 were fine yesterday, both ending up in the Good AQI range.As for today, we are forecasting PM2.5 to return to the Good category, as long as there aren't anymore surprise PM2.5 spikes like yesterday. Ozone will continue to hover around the upper Good to lower Moderate AQI range through the week. We expect Friday and Saturday to have lower concentrations due to a trough moving through the region.
Particulates are forecast to stay in the Good AQI category through the forecast period. There will be some breeziness each afternoon, but the strongest winds are forecast to be on Friday as the trough moves through. We are forecasting wind gusts up around 30-35 mph. This may increase PM10 concentrations a little during the gusty winds, be overall we don't expect any significant dust in Tucson.
