Forecast Discussion: Ozone concentrations will be higher Thursday than in the past couple of days, but should remain in the upper good range. Clouds and limited sunshine on Friday with perhaps afternoon and evening thunderstorms will put a lid on how high ozone can increase, and as a consequence, upper good levels are more likely. Onshore flow over the weekend will promote more cloudiness, and a continued chance for unsettled weather, so ozone will likely remain in the good range during this period.
