Synopsis and Discussion
With weak high pressure keeping the Triad under mostly clear and dry skies, air quality levels have risen into the low to middle Code YELLOW range this afternoon. Ozone remains the primary driver for today's AQI, as the weak surface ridge and light winds/lower dewpoints have provided a favorable environment for ozone production. Moderate AQI levels should thankfully be short-lived as the weak surface high erodes and hot/humid air moves in from the southwest overnight and through tomorrow. Southwesterly winds are expected to increase in magnitude and become quite gusty during the day, likely resulting in fire weather danger due to the prolonged extreme drought. With that said, increasing dewpoints and low-level dispersion should limit pooling of pollution concentrations tomorrow and keep air quality levels in the upper Code GREEN range. Newly formed Tropical Storm Arthur, currently situated along the south Texas coastline, is expected to have a short life span as it gets absorbed into the upper level trough and pushed east-northeastward towards the southeastern United States. Rain chances will likely increase for the Triad late Thursday through Friday morning as the remnants of Arthur interact with an approaching cold front, though precipitation totals are not expected to be impressive. However, the increase in cloud cover should help keep air quality levels well within the Code GREEN range on Friday as we head into the weekend. Dry high pressure on Saturday will keep skies clear and dry, with air quality levels approaching the upper portion of the Code GREEN range. (Payne)
