Forecast Discussion: Current Conditions: At 2 p.m. EDT this Thursday afternoon, high pressure over Ohio continues to bring a northerly flow of dry and cool air across the region. With more clouds than sunshine, ozone formation has been limited to the good range. The dry air has also kept fine particulate levels low. As the high moves overhead, then to our east over the next few days, both temperatures and humidity levels will be on the rise. Things will start off cloudy this evening, but the sky will turn out mostly moonlit later on tonight. Fine particulate will move into the moderate range later on. Lows will drop into the middle 50s. *** Friday's forecast: Warmer Friday with sunshine and a few clouds. With winds becoming light and shifting into the southwest, fine particulate will increase, but overall averages for the day will remain in the upper good range due to the dry air. Ozone production will also rise, but levels will only rise into the upper good range. Clear to partly cloudy and not as cool Friday night with lows in the upper 50s. *** Extended forecast: Light southwest winds with a good deal of sunshine will boost ozone levels into the moderate range Saturday. Increasing humidity with the southwest winds also means fine particulate moves into the moderate range. Afternoon temperatures in the lower to middle 80s. A warm front bringing clouds and a shower or two Sunday might limit ozone again, but fine particulate remains moderate. Early next week will bring more very warm and humid conditions to close out August, and mainly moderate air quality.---McAuliffe
