Synopsis and Discussion

High pressure building in from the north has kept the Triad under a drier and cooler air mass today, resulting in pleasant fall-like conditions and Code GREEN AQI for ozone and particle pollution. Upper level troughing will continue to keep the Triad under dry and cooler high pressure through the week, keeping areas of disturbed weather well to the south and east through Thursday. The upstream air mass to the north also remains Code GREEN for both pollutants, which should reinforce Code GREEN AQI for the Triad over the next few days. Maximum temperatures are expected to slowly tick upward through the end of the week as conditions remain quite dry, possibly resulting in ozone levels creeping into the lower Code YELLOW range for Thursday. For now, will keep a high Code GREEN for the Triad and monitor the next couple of days to see if the forecast needs an upgrade. (Payne)
