Triad Air Quality

Triad Forecast

Synopsis and Discussion

As anticipated, another day of low Code YELLOW AQI has impacted the Triad this afternoon as high pressure continues to remain dominant across the mid-Atlantic states. A low pressure system centered well offshore to the south has strengthened and may become a tropical storm before moving northward tomorrow. The Triad should remain mostly dry for the better part of the day, but increasing cloud cover and low-level dispersion should keep ozone levels in the upper Code GREEN range. However, particle pollution will likely remain moderately elevated as east to northeasterly winds push particulates towards the west and accumulating along the lee side of the Appalachian mountains. Eventually cleaner maritime air will move into the Triad as the potential tropical low moves closer to land Friday evening, which should result in low to middle Code GREEN AQI through the day on Saturday. It is hard to say how much rain may impact the Triad from the storm system, but gusty winds and cloudy skies should keep pollution production at a minimum. The storm should move off to the north on Sunday, with increasing sun and lighter winds allowing ozone and particle pollution levels to rebound into the middle to upper Code GREEN range. (Payne)
