General Forecast Discussion
High pressure will build in on Sunday following the cold frontal passage on Saturday. Despite the light and variable winds, fine particulate levels should be in the Code Green range thanks to the clean air mass that filtered in behind the front. Maximum 8-hour ozone levels will also hold in the Code Green range thanks to some mid and high level clouds.
Outlook
On Monday, low pressure will develop over the Gulf states and travel up the east coast. This will bring rain to the southern portions of North Carolina, and gusty winds to the eastern half of the state. Air quality is expected to hold in the Code Green range. Tuesday will be sunny and dry as high pressure builds in again, and fine particulates and ozone levels will creep up into the upper Code Green range.
Daily PM2.5 values > 9.0 μg/m³, or in the Code Yellow range or higher, may contribute to an exceedance of the EPA's annual PM2.5 standard.
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.
