General Forecast Discussion
Air quality will consistently hold in the good to moderate range through Monday with very little variety. There’s not a lot going on in the mid/upper levels in our region besides weak ridging. At the surface, an area of low pressure retrograding westward over the southeast may help increase storm coverage on Monday. All in all, a continuation of hot, humid days with afternoon storms. Calm to light winds and air mass stagnation will be the main air quality concern in areas that don’t see any significant convection.
Outlook
Pretty persistent forecast for Tuesday. Air quality will likely drop a bit with the repeated rain/unsettled weather and max out in the upper Code Green range everywhere.
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.
