Forecast Discussion:
Ozone levels stayed in the Moderate AQI category yesterday, while PM10 and PM2.5 were in the Good range. Today, ozone is forecast to stay in the lower Moderate range. After today, more southerly winds each day should help to lower ozone into the Good category. As for particulates, we are looking at potential for outflow winds reaching the Yuma area late Thursday and early Friday, which may kick up a little dust. However, good rain coverage over the lower deserts will hopefully prevent any significant dust. We are forecasting PM10 and PM2.5 to stay in the Good range through the forecast period.
