Forecast Discussion: It will be an unsettled weekend for the State of Delaware. Saturday will be cool and less windy, with mostly sunny skies in the morning and increasing clouds in the afternoon as a low pressure system approaches. Particle concentrations will rise in response to light winds, but sufficient vertical mixing and an unmodified air mass will keep air quality in the Good range. Sunday will be slightly warmer with a chance for rain beginning overnight and continuing into the morning. A period of stagnation in the morning will allow particles to rise to the top of the Good range. Breezy northwesterly winds on Monday will ventilate the atmosphere and drop particles lower into the Good range. **Extended Forecast: Weak surface high pressure will build into the Mid-Atlantic region on Tuesday. Continued breezy winds will extend the period of Good air quality. -Huff
