Forecast Discussion: Current conditions: At 2 p.m. EDT this Wednesday afternoon, skies are mostly sunny for the time being, but a weak frontal system is causing thunderstorm activity to pop in parts of the area as well. Ozone levels are moving into the moderate range, with low moderate levels of PM2.5 as well, as mixing is light and limited. A thunderstorm in parts of the partnership area this evening, otherwise mostly clear later on with areas of fog forming. *** Thursday's forecast: Light west-southwest winds and a good deal of sunshine will allow favorable conditions for ozone development, so upper moderate concentrations are likely in parts of the area Thursday. Fine particulate will remain low moderate due to light winds and higher humidity. Afternoon temperatures will move into the upper 80s. *** Extended forecast: We will enter into a period of wet weather later Friday into Friday night as a cold front approaches and remnants of Cindy move along it with showers and thunderstorms likely. Ozone concentrations Friday will fall back into the good range, with fine particulate also improving to the good range. Morning rain is likely early Saturday, then clearing and breezy conditions by the afternoon with good air quality and sunshine returning. Periods of clouds and sunshine for Sunday with pleasant conditions and continued good air quality.---McAuliffe
