Forecast Discussion: High pressure is providing plenty of sunshine this Friday afternoon. A clean and dry northwesterly flow is bringing low levels of ozone. While ozone might increase over the next couple of days with warm air and higher humidity, concentrations are expected to remain in the upper good range. The only day there might be marginal moderate readings will be Monday, but convection by the afternoon may act to limit how high ozone levels go. Cooler and drier air will arrive by the middle of next week, leading to good air quality.---McAuliffe
