Forecast Discussion: Thursday will be another pleasant summer day, more reminiscent of late May than the end of July. There is a chance for an isolated afternoon shower or thunderstorm, but otherwise skies will be mostly sunny. Light southwesterly winds, with an afternoon sea breeze, and a gradually modifying air mass will allow ozone to reach the low Moderate range at locations along I-95. Particle concentrations will rise but remain in the upper Good range. **Extended Forecast: Increasing cloud cover and more scattered showers on Friday afternoon will limit air quality to the Good range. A frontal boundary will stall along the Atlantic coast on Saturday, promoting overcast skies and widespread showers, which will keep air quality well inside the Good range. -Huff
