Forecast Discussion:

PM10 levels stayed in the Good AQI range yesterday, while PM2.5 barely managed to reach the Moderate category. Looking ahead, generally calm conditions are expected today and tomorrow. On Friday and Saturday, there will be a weak trough moving through the region, which may bring some breezy afternoon winds. Then calmer conditions are expected to return on Sunday.

As for air quality, we don't expect any weather conditions that would cause any major issues. Morning and evening particulate levels have been getting a little elevated under these calm conditions. As a result, PM2.5 may again reach the low Moderate category again today and tomorrow.
