General Forecast Discussion
Monday into Tuesday, a cold front will sweep across the state Monday afternoon and usher into renewed cool and dry advection along with a clean air mass that should hold air quality levels in the Code Green range through the period.
Outlook
Wednesday, high clouds well out ahead of what is expected to be Hurricane Ian should overspread the region from the south. This should be a limiter on ozone formation -- in tandem with the late September sun -- and hold ozone levels well inside the Code Green range. A clean and very dry air mass should also continue to keep particle pollution levels in the Code Green range through midweek.
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.
