Forecast Discussion: At 2 p.m. EDT this Friday afternoon, a cleaner and drier northwesterly flow has limited ozone formation to the good range. High pressure will bring full sunshine for the day Saturday with a rather warm afternoon. Nonetheless, ozone concentrations will remain at the top end of the good range. A weak upper level low pressure area might bring increasing chances for convection later Sunday into Monday. The convection will result in ozone varying between upper good and lower moderate, depending on the amount of sunshine there is. A cooldown may be in the offing later next week just in time for the start of September.---McAuliffe
