Synopsis and Discussion

With high pressure holding steady over the Triad putting a lid on any attempt for convective development, rising temperatures have allowed for air quality levels to rise into the upper Code YELLOW range today. We may see a few hourly ozone concentrations reach Code ORANGE later this afternoon during rush hour, but air quality levels should gradually fall with the loss of solar heating this evening. Another relatively warm day is on tap for tomorrow as the offshore high pressure is expected to generate a light southwesterly flow throughout the day. Currently elevated ozone levels across the I-85 corridor will gradually make their way into the Triad tomorrow under the persistent southwest flow. Low-level moisture may increase slightly as some showers develop in the mountains, but the Triad shouldn't see anything more than an isolated shower at best. With that said, the persistent weather pattern is favorable for ozone production and is expected to add on to the sourcing from the southwest---likely bringing the Triad its first Code ORANGE aka Air Quality Action Day. A slight drop in ozone levels is expected Friday with the approach of the developing low pressure system off the coast, but the area should remain dry enough to sustain upper Code YELLOW conditions. Onshore flow on Saturday should bring down air quality levels into the upper Code GREEN to low Code YELLOW range. (PAYNE)
