Synopsis and Discussion

Despite cold and dry high pressure residing over the Triad, air quality levels have remained Code GREEN this afternoon as an increase in northeasterly winds have generated plenty of low-level dispersion while ushering in a cleaner air mass from the mid-Atlantic region. Another chilly start to the day tomorrow will likely lead to a decent low-level temperature inversion in the morning hours to trap particle pollution close to the surface. Unlike today, increasing cloud cover through the day on Thursday will likely prevent abundant dispersion of pollution particles that is typically observed when the boundary layer grows during daylight hours. With that said, particulate matter concentrations will likely build into the lower Code YELLOW range early and remain there through the evening hours. A weak cold air wedge is expected to develop over the Triad early Friday as an area of disturbed weather moves in from the west. Rain chances will likely stay low during the morning, but gradually increase into the afternoon as the frontal boundary moves into the area late Saturday. Thus, air quality levels will likely remain Code YELLOW until Saturday evening when widespread showers should help wash out elevated particle pollution concentrations. Dry and mild weather on Saturday should bring Code GREEN air quality to the Triad. (Payne)
