Forecast Discussion: Ozone concentrations are being held to the upper good range this Friday afternoon as pleasant conditions continue. With high pressure moving off the east coast late this weekend into early next week, ozone levels will be on the increase, and moderate readings are possible as temperatures climb into the middle and even upper 80s to start September, a level 10 degrees warmer than average. The one limiting factor in ozone concentrations will be a warm front coming in Sunday and Sunday night, which could bring a shower or thunderstorm. The highest ozone readings are likely after this warm front passes early next week, and will go into the moderate range in spite of a lowering September sun angle.---McAuliffe
