Forecast Discussion: Saturday will be warmer and more humid than the past few days as winds shift to the southwest. The air mass in place across the Delaware Valley is low in pollutants and their precursors, and as a result, air quality has been persisting well inside the Good range for the past few days. Another day of mostly sunny skies and very light surface winds on Saturday, particularly in the morning, should be enough to finally push ozone into the Moderate range. Particle concentrations will rise in response to increasing humidity and stagnant winds, but will remain in the upper Good range. **Extended Forecast: The warming trend that began on Saturday will continue on Sunday and will extend into at least the middle of next week as a “ridge” of high pressure builds over the Mid-Atlantic region. High temperatures on Sunday and Monday will hit the low 90s F, and humidity will steadily increase as well. Ozone and particles will be in the Moderate range both days, with higher concentrations on Monday due to westerly transport aloft, which is typically rich in pollutant precursors. Partly cloudy skies on Sunday will also help to keep ozone lower in the Moderate range. -Huff
