General Forecast Discussion
Persistent onshore flow courtesy of Bermuda high pressure and several weak perturbations aloft and at the surface will result in a classic summertime pattern with warm temperatures and scattered to numerous afternoon showers and thunderstorms. Overall, this should hold air quality levels near the Code Green range, with hourly ozone likely to be highest in the Charlotte region, especially on any days that don't receive rain.
Outlook
Hot, humid and mostly good air quality conditions are expected through the week.
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.
