Triad Air Quality

Triad Forecast

Synopsis and Discussion

Air quality levels remain well within the Code GREEN range today as periodic showers and cloudy skies have prevented production & accumulation of pollution concentrations. A cut-off upper low over the lower Mississippi River valley has continued to pull persistent deep plume of moisture from the Gulf of Mexico into the southern Appalachians ahead of Hurricane Helene, which is expected to make landfall in the Big Bend area Florida this evening. Helene is expected to weaken while quickly moving northward into the southern Appalachians by Friday morning as the upper low pulls it north, then northwest into the Tennessee/Kentucky Valley. The Triad should mostly remain outside of the direct effects of the storm, but heavy rain and gusty winds are expected late tonight and through Friday morning. Conditions are expected to gradually ease through the afternoon, but any breaks in the cloud deck will be brief and AQI should still remain in the low to middle Code GREEN range. Saturday should be a mostly pleasant day for the Triad, but southerly winds should continue to be persistent enough to limit ozone and particle pollution levels into the middle to upper Code GREEN range. Clouds are expected to increase on Sunday with an isolated chance of showers, keeping air quality levels in the middle to upper Code GREEN range. (Payne)
