Forecast Discussion: The westward extension of a Bermuda High on Wednesday will result in clear skies and sustained southwesterly surface winds for most of the day. The arrival of a cold front by the end of the day will trigger cloud cover and scattered rain showers in the evening. Mostly all-day sunshine and increased levels of atmospheric moisture will allow air quality to remain in the Moderate range. **Extended Forecast: The passage of the cold front will bring in a dry and relatively cooler air mass in its wake. Northwesterly surface winds will prevail along with all-day scattered rain showers and clouds. Air quality will be reduced to the Good range. High pressure will build in over the Philadelphia metropolitan area on Friday marking a return to pleasant summer weather. Sunny skies, light winds, and an afternoon sea breeze will allow ozone to rise into the Moderate range while the cool and dry air mass will keep particles in the Good range. -Catena/Huff/Herdt
