Despite being under some of the strongest solar radiation of the year as we enter meteorological summer, our Air Quality has been remarkably Good. This can be attributed to several factors such as wind blowing in from clean regions, cooler temperatures, and low humidity. Those dynamics should remain in play through mid-week, at least. Beginning Thursday, the large semi-stationary high-pressure ridge which has been responsible for our great weather for the past two weeks will finally migrate east and our wind pattern will shift to a more southern component. That means we can expect a modest rise in surface temperatures and humidity, although the air will still be relatively dry for this time of year. With that shift, we can expect a slow creep upwards in ozone concentrations although with the clean background, I am not expecting any immediate widespread excursions into USG territory. For Fine Particulates, a check of Canadian wildfires and observed smoke is showing relatively low activity for this time of year. Crossing fingers and hoping that trend continues although drier conditions are expected. I will tempt fate by writing this forecast through Friday. However, I will be closely checking end-of-week conditions and will upgrade this forecast, as necessary. EXTENDED FORECAST: Air Quality is expected to be Moderate entering the weekend as temperatures and humidity continue to increase.
