Forecast Discussion: Good air quality is currently expected through Friday. Wednesday, after a cold start, will have Good air quality with a clean airmass in place. As some recirculation of air occurs on Thursday and with ample sunshine, both ozone and fine particles will increase. However Good air quality is maintained with below normal temperatures, increasing cloud cover and clean easterly winds. Mainly overcast conditions Friday will limit ozone concentrations but fine particles may increase towards the Moderate threshold under an inverted marine airmass. - MDE
