PM10 was in the Good AQI range yesterday. The next couple of afternoons could have brief increases in concentrations because of storm development, but overall the rainfall in recent days will help limit how much is brought to the area. Early next week, forecasts hint at showers and storms coming from the south in the afternoons, so hourly PM10 levels have been adjusted to show that potential. Despite the potential of storms, PM10 is forecast to be in the Good AQI range through early next week.
