Triad Air Quality

Triad Forecast

Synopsis and Discussion

Soggy conditions and cloudy skies resulting from a slow moving cold front have kept air quality levels well within the Code GREEN range today. The frontal boundary should sag south of the Triad later this evening and allow for the development of cold air damming east of the Appalachians as a surface ridge of high pressure nudges in from the north. A conveyor belt of upper level moisture moving in from the Gulf of Mexico will help lock in the cold air wedge Friday and periodic showers should help keep air quality levels in the middle Code GREEN range. Shower activity is expected to become less frequent as the day progresses on Saturday, but the cold air wedge should remain in place long enough to keep particle pollution levels within the middle to upper Code GREEN range. Erosion of cold air damming should take place Saturday night into Sunday morning with the advancement of a cold front moving in from the west. The quick moving front should help clear out skies by Sunday afternoon, but gusty westerly winds in the front's wake should generate considerable low-level dispersion to prevent particle pollution buildup.
