Forecast Discussion: Moderate air quality is expected this weekend as high pressure builds over the mid-Atlantic. The transition to higher fine particle concentrations begins this evening as winds diminish, becoming near calm by daybreak Saturday. Air quality will begin Saturday in the Good range but, by afternoon, will reach into the Moderate range. Extended Forecast: Fine particle levels will peak on Sunday in the mid-upper Moderate range. Overcast skies will limit vertical mixing and allow particles to accumulate. Winds will shift northeast Sunday afternoon and slowly increase through the evening. By Monday, strong east to northeast winds associated with another offshore storm will provide enough ventilation to improve air quality back to the Good range. -Ryan
