Synopsis and Discussion

Code ORANGE particle pollution was observed across the Triad for the first half of the day. Concentrations have decreased considerably and daily averages will net out in the upper Code Yellow range as air quality continues to improve as the day wears on. The southwesterly flow and storms that will help improve air quality today will keep AQI readings in the lower Code Yellow range tomorrow. The backdoor front mentioned in yesterday’s forecast discussion is still slated to approach the area on Monday morning. Models still differ with respect to its southward progression and it’s still unclear how much smoke will be behind the front. Assuming it does make into the Triad for at least a few hours and there is some smoke in its wake, particle pollution could reach the mid to perhaps upper Code Yellow range on Monday. The boundary will be quick to retreat northward, allowing conditions to improve on Tuesday. Storm chances will continue to be a mainstay in the weather forecast and ozone will be held in check as a result. (Greg Perrotte / perrotgt@forsyth.cc)
