Synopsis and Discussion

Not much has changed for the Triad's air quality today, as ozone and particle pollution levels continue to remain well within the Code GREEN range. Ozone formation continues to be significantly hampered by high dewpoints. The upper level ridge that has kept the Triad under this persistently hot and humid air mass will retrograde to the west and allow for northwesterly flow aloft the next several days. Tomorrow will be another day of hot and humid conditions, but a backdoor front diving in from the north is expected to usher in a cooler and slightly drier air mass for Tuesday into Wednesday. Air quality should continue to remain Code GREEN on Monday, but particle pollution levels are expected to trend upward as upwind sourcing from Canada may give the Triad some residual wildfire smoke particles that could elevate AQI. For now, air quality levels are expected to remain in the upper Code GREEN range at the very least, but subsequent forecasts may lead to higher numbers for forecasted ozone and particle pollution AQI.
