Forecast Discussion: Current Conditions: We are having another fine late summer day across the region this Tuesday afternoon courtesy of high pressure which is just off to our east. Temperatures moving into the middle 80s are resulting in ozone levels rising into the lower moderate range, and fine particulate is also remaining moderate this afternoon. Humid tonight with patchy cloudiness. Fine particulate will remain in the moderate range. *** Wednesday's forecast: Clouds and some sunshine on Wednesday as a cold front approaches the region. Showers and a thunderstorm will also develop in a few locations. Developing clouds will prevent ozone from rising above the lower moderate range, and fine particulate will remain moderate as well. Temperatures will max out in the lower 80s. Turning cooler Wednesday with improving air quality. Lows will drop into the middle 50s. *** Extended forecast: A cooler and drier north to northwesterly flow of air will prevail on Thursday, and bring mostly good air quality. With some sunshine, highs will reach the upper 70s. Winds will shift into the southwest late in the week into the upcoming weekend, and chances for thunderstorms will also increase late Saturday into Sunday. Good to low moderate air quality is likely for Friday, then deteriorations to the moderate zone are possible Saturday. Ozone levels should drop into the good range by Sunday with more clouds than sunshine.---McAuliffe
