Forecast Discussion: Mostly cloudy skies throughout Delaware will limit ozone to the Good range on Friday. Canadian wildfire smoke will continue to influence particle concentrations. As a result, Moderate particle levels will persist, aided by light surface winds. **Extended Forecast: A bout of widespread precipitation will move through the state during the early morning on Saturday. The continued presence of wildfire smoke, along with local Independence Day fireworks, will keep particle concentrations in the Moderate range. Skies are expected to be cloudy for most of the day, which will keep ozone in the Good range for another day. Clearer skies and light winds will push ozone into Moderate range on Sunday, with the potential for isolated upper Moderate condition. Particle concentrations will remain in the Moderate range as smoke and emissions due to holiday travel continue to impact air quality. -Eherts/DeBoe/Huff
