Forecast Discussion: Current conditions: Winds have shifted into the southwest this Wednesday afternoon, bringing in slightly more humid air. With the sunshine and warmth, ozone concentrations have risen into the moderate range with fine particulate levels in the upper good range. Mostly clear and mild tonight with temperatures falling back into the middle 60s. *** Thursday's forecast: Partly to mostly sunny and warm for Thursday with ozone and fine particulate going into the moderate range. Temperatures will rise into the middle and upper 80s. *** Extended forecast: Partly sunny skies and continued rather warm for Friday with a better chance for thunderstorms late in the day. Ozone levels still can go into the moderate range, with fine particulate remaining moderate as well. The weekend looks more muddled as a trough of low pressure keeps chances for afternoon and evening thunder going. Overall air quality will be mostly in the lower moderate range.---McAuliffe
