Forecast Discussion: High pressure will shift eastward today and will be centered just east of Cape Hatteras by Monday morning. Winds will be light overnight and early Monday allowing particle concentrations to increase. Ozone will also increase as Delaware will see sunny skies and transport of pollutants from the B-W Corridor during the day Monday. Expect Moderate air quality Monday. Extended Outlook: Sunny, warm and humid on Tuesday with a chance of late afternoon thunderstorms as a front approaches. The forecast models are not yet in agreement on the timing of clouds and rain so we will continue to hold air quality in the Moderate range for both fine particles and ozone. Improving air quality Wednesday after the front passes. -Ryan
