Forecast Discussion: It will be a lovely Easter holiday weekend for Delaware, with mostly sunny skies and seasonable temperatures. A weak cold front will approach northern Delaware on Saturday morning and then dissipate. The main effect will be a shift in surface wind direction to the north. Stagnation overnight will cause particle concentrations to rise during the morning hours. Transport aloft from the Central Plains, where agricultural fires are producing smoke, will also contribute to rising particle concentrations early in the day. Although northerly winds in the afternoon will ventilate the atmosphere and reduce particle concentrations, the daily average will be in the low end of the Moderate range. Surface winds will shift back onshore (east/northeast) on Sunday under the influence of surface high pressure centered over southern Canada, which will return air quality to the Good range. Rising atmospheric humidity on Monday, along with light winds in the morning, will push particle concentrations to the Good/Moderate threshold. **Extended Forecast: A cold front will approach from the northwest on Tuesday, bringing a chance for rain showers in the evening. Warm and humid conditions ahead of the front for most of the day will keep air quality in the Moderate range. -Huff
