Forecast Discussion: Friday will be a cool day in Delaware. Humidity and cloud cover will increase under persistent onshore (northeasterly) flow. The onshore winds will transport clean maritime air into the state and keep air quality in the Good range. **Extended Forecast: A weak cold front/surface trough will pass through Delaware early Saturday morning. The main effect will be a shift in surface wind direction to the north. A period of stagnation overnight and into the morning will cause particle concentrations to rise. Steady northerly winds in the afternoon and ample vertical mixing will ventilate the atmosphere, however, and limit daily average particle concentrations to the upper end of the Good range. Winds will shift back onshore on Sunday under the influence of surface high pressure centered over southern Canada. Good air quality will continue. -Huff
