Synopsis and Discussion

Air quality levels have returned to the GREEN range as northwest winds and cooler temperatures move into the region. This pattern will continue for a couple more days as high pressure slides to the southeast and controls the weather in the state through Saturday. Wind speeds will decrease and become more variable by Friday, which could allow AQI levels to just reach the lower YELLOW range. Highs will hold in the upper 60s and lows could fall into the upper 30s. While this weather pattern will help keep air quality in the GREEN range for a couple days, expect YELLOW AQI readings to return Friday and hold through the weekend. (Bodenhamer)
