Today's Air Quality Conditions
Current daily average fine particulate concentrations are lingering in the Code Yellow range near Charlotte as well as near Greenville in Pitt County as of this afternoon, mainly due to some higher overnight readings. Hourly values have dropped into the Code Green range at most locations as the frontal boundary crosses the state this afternoon.

General Forecast Discussion
Code Green air quality is expected on Tuesday and Wednesday following the strong frontal passage from Monday. A lee trough looks to develop over the area, and with the pressure gradient between this and the high to our west, somewhat breezy conditions will persist. That should help with dispersing any fine particulate emissions that may result from increased residential woodburning as well as any fireworks on New Years Eve.
Outlook
A weak area of Canadian high pressure approaching from the northwest on Thursday will introduce a weak cold front around midday, which should help should keep the atmosphere well mixed. Code Green is expected statewide on Thursday as well.
Extended Air Quality Outlook
The forecast Air Quality Index value for each pollutant represents the highest value expected within each county, so some areas and monitors may see lower values. We use the best information and techniques available to ensure the quality and accuracy of the forecasts we provide to the public. Note that ranges do not include the nine-county Triad region, which is covered by the Forsyth County Office of Environmental Assistance and Protection.
