Triad Air Quality

Triad Forecast

Synopsis and Discussion

The Triad remains in transition between yesterday's slightly cooler and drier air mass and tomorrow's expected heat and humidity, with today's high temperatures and light winds/lower humidity providing a favorable environment for ozone production. Despite the lower pollution emissions typically observed on weekends, air quality levels have risen into the lower to middle Code YELLOW range. As stated previously, conditions will be hotter and more humid tomorrow ahead of a cold front approaching from the northwest. Increasing southwesterly winds and high dewpoints ahead of the front should inhibit ozone growth, and the increase in afternoon cloud cover should help to drop air quality levels to the upper Code GREEN range before the early evening. Chances of rain increase as the frontal boundary passes through the Triad late tomorrow evening into Tuesday morning, with a drier air mass moving into the state from the west by the afternoon. Morning clouds and possible lingering shower activity on Tuesday will likely keep air quality levels at a minimum to start, but a drying northwesterly flow in the afternoon will likely increase ozone production enough to elevate air quality AQI into the upper Code GREEN range. Weak high pressure settles over the Triad on Wednesday, as another warn and dry day coupled with light winds/clear skies should help to elevate ozone levels into the lower Code YELLOW range. (Payne)
