Forecast Discussion: The high pressure ridge that has resided over the Triad over the last few days will continue to break down and allow for warm, moist southwesterly flow to return to the area. The air mass will unfortunately be slow to turn over, likely allowing air quality levels to remain Code YELLOW for today. Scattered showers and storm chances increase Monday and Tuesday, leading to Code GREEN ozone and particle pollution levels by Tuesday afternoon. High pressure builds in from the north on Wednesday, but cooler temperatures will likely allow for air quality levels to remain Code GREEN. (Payne) |
