Synopsis and Discussion

Air quality levels have increased into the low YELLOW range as southwest winds, clear skies, and high temperatures push into the mid 70s Tuesday afternoon. A mostly dry cold front will slide through the Triad this evening and shift winds to the northwest, which will help return AQI readings to the GREEN range for Wednesday and Thursday. High pressure will dominate our region as cooler air makes its way into the Triad. High will hold in the upper 60s and lows could fall to around 40. While this weather pattern will help improve air quality for a couple days, expect YELLOW AQI readings to return Friday. (Bodenhamer)
