Triad Air Quality

Triad Forecast

Synopsis and Discussion

Air quality levels remain Code YELLOW this afternoon as an upper-level ridge has allowed for near record high temperatures for much of the Triad. The upper-level high pressure ridge has kept clouds and precipitation largely confined to the north in Virgina throughout the day, though a backdoor frontal boundary has been nudging in from the northeast that has likely hindered higher pollution AQI numbers for the Triad. This weak boundary will quickly erode overnight and through tomorrow as southwesterly winds increase ahead of a strong cold front advancing in from the west. Temperatures should once again approach near record levels again tomorrow, but the increase in wind dispersion should limit pollution concentration accumulation and keep ozone and particle pollution AQI in the low Code YELLOW range. Chances of rain increase tomorrow night as the cold front moves through overnight, ushering in a much cooler and drier air mass for the weekend. With that said, air quality levels will easily drop to mid-Code GREEN AQI for both pollutants for Saturday and Sunday. (Payne)
