Forecast Discussion:
Pollution levels remained in the Moderate AQI range yesterday for ozone, PM10, and PM2.5. We aren't expecting a whole lot of change today. First, looking at ozone, calm winds and sunny skies will likely allow ozone to reach the upper Moderates today. We do forecast ozone to improve a little tomorrow through the weekend with better winds aloft. Then with a ridge strengthening over the region early next week, ozone will likely start trending back up. Overall though, ozone is forecast to remain in the Moderate AQI range through the forecast period.Calm conditions have allowed particulate levels to be elevated, particularly during the morning and evening hours. We are forecasting PM10 to hang on to the Moderates through tomorrow, then drop into the Good range over the weekend with better ventilation and less dust-generating work activities. PM2.5 will follow a similar trend, but may drop into the Good range as early as tomorrow. Both PM10 and PM2.5 are forecast to return to the Moderate AQI range on Monday with calm, dry, and stable conditions.
