Forecaster's note
Current Conditions: The air quality briefly reached the lower-end moderate range this morning in parts of the Pittsburgh area, but the air quality has now improved to the good category as the sunshine caused vertical and horizontal mixing of the air. A cold front will sweep through the area this evening, causing a change in wind direction from the northwest, promoting good air quality. *** Thursday’s Forecast: Warmer air will be located just above the ground early Thursday morning, which can cause moderate air quality to start the day as fine particulates (PM2.5) are trapped near the ground.
