O3 = Ozone, PM10 = Particles ≤ 10 microns, PM2.5 = Particles ≤ 2.5 microns

Forecast Discussion:

PM2.5 levels reached back into the Moderate AQI range yesterday and will likely remain there the next few days. Dry, calm conditions through the weekend should allow particulate levels to remain elevated, especially during the morning and evening hours. We forecast PM2.5 to stay in the Moderate range until Tuesday or Wednesday next week when a trough moving into the area will provide better ventilation over the area. PM10 levels continue to be fairly low due to the recent rain, and should stay in the Good AQI range through the forecast period. Ozone will also stay in the Good range as it's still a little early in the year for ozone issues.
