Forecast Discussion: A front will approach the Atlantic coastline from the east on Friday as surface high pressure retreats to the Canadian Maritimes. Mostly cloudy skies in the afternoon and scattered showers associated with the front will limit ozone to the Good range. Stagnating surface winds in the morning and rising atmospheric humidity will allow particle concentrations to remain in the low Moderate range. **Extended Forecast: The frontal boundary will remain draped along the coast over the weekend. Waves of low pressure will ride along the front from south to north, generating periods of heavy rain, particularly on Saturday. In addition, light onshore flow will bring clean maritime air into the state. As a result, Good air quality is expected for both Saturday and Sunday. -Huff
