Forecast Discussion:
Ozone and PM2.5 stayed in the Moderate AQI range yesterday, while PM10 ended up in the Good range. We continue to be under a strong high pressure system, but fortunately, there is finally an end in sight. Later this weekend and into early next week, a weak low pressure system will move underneath the ridge. That will help weaken the ridge, and by later next week the ridge should finally move out of the region. In the meantime, we still expect warm and mostly quiet weather condition, with a slow downward trend in temperatures.
As for the air quality, ozone is forecast to hang on to the low Moderates for a couple more days. By Sunday, slightly better ventilation should bring ozone down into the upper Good range. PM10 is forecast to continue in the Good AQI range through the forecast period, while PM2.5 will continue to hover between the upper Good and lower Moderate range.
