Forecast Discussion: Partly sunny skies on Tuesday will increase ozone compared to the past several clean days. However, increased surface winds in the afternoon will help to limit concentrations to the low Moderate range. Wednesday will be mostly clear, helping ozone concentrations reach into the Moderate range. Particle concentrations will likely reach into the Moderate range as well. There is a chance of smoke from Canadian wildfires reaching the region by Wednesday. Thursday will be cloudy with scattered showers, limiting ozone to the Good range. However, stagnant converging winds and the continued threat of smoke will help push particle concentrations into the Moderate range for another day. - MDE/PSAQFO
