Triad Air Quality

Triad Forecast

Synopsis and Discussion

Ozone levels have been quite volatile across the Triad this afternoon as isolated showers and storms have generated localized outflow boundaries that have accumulated pollution concentrations ahead of the downdrafts that led to ozone AQI to briefly reach Code ORANGE for a few hours. Eventually the outflow from the storms should provide enough cleanout to reduce pollution concentrations to Code YELLOW for ozone and particulate matter concentrations daily averages. Weak upper level forcing will remain over the Triad tomorrow and through the weekend, providing enough of a forcing mechanism to initiate isolated showers and storms each afternoon during peak heating hours. High temperatures are expected to remain above normal each day, with high low-level moisture content continuing to inhibit ozone production. With that said, air quality levels will likely trend downward the next couple of days, but ozone and particle pollution are expected to stay in the Code YELLOW range through Sunday.
