Forecast Discussion: Sunday will be a pleasant end to the Independence Day holiday weekend, with seasonable temperatures and relatively low humidity. Sunny skies and stagnant winds will allow ozone to quickly climb to the top of the Moderate range. Low regional pollutant concentrations should keep ozone out of the Code Orange range. Another pulse of Canadian wildfire smoke is expected to make its way into the Philadelphia metro area, for continued Moderate particle air quality. **Extended Forecast: Monday will be warm and increasingly humid. Partly sunny skies and light surface winds will allow ozone and particles to persist in the Moderate range. A shift to onshore winds and increased chances for clouds and scattered precipitation on Tuesday will push ozone and particles slightly lower into the Moderate range. -Huff
