Forecast Discussion: Current Conditions: As of 2 PM on Wednesday, mostly sunny skies prevail across much of eastern PA as an area of high pressure continues to reside over the northern Mid-Atlantic region. Right now, light variable winds along with the brilliant sunshine are helping to drive temperatures near the 90 degree mark. The combination of the sunny and warm conditions are forcing ozone levels to rise into the low moderate category. PM 2.5 levels have been slower to increase because of the lower dewpoints over the region (as compared to a couple of days ago). Expect moderate air quality to persist into tomorrow as conditions stay warm and become more humid. *** Thursday's Forecast: So for Thursday, expect mostly sunny skies in the morning to give way to increasing cloudiness in the afternoon as the area of high pressure over the northern Mid-Atlantic region begins to break down. A frontal system draped over the central Mid-Atlantic will allow a disturbance to move from west to east along it. This disturbance is likely to trigger some shower development, although it is primarily expected to occur late in the day. Southerly flow over the region will allow temperatures to reach near 90 again. The combination of the warm temperatures and increasing humidity levels will force PM 2.5 levels into the moderate range. Ozone, on the other hand, will stay on the lower end of moderate thanks to the increasing afternoon cloud cover and rain chances. *** Extended Outlook: Over the coming days, expect to see cloudy skies prevail across the region early on as a stationary frontal system across the Mid-Atlantic continues to be the focal point of shower activity. Temperatures will remain in the 80s with air quality levels likely hovering near the good / moderate range. Expect temperatures to begin to moderate next week as higher pressure and clearer skies persist. The additional sunshine during the week and the increased stability is likely to force ozone and eventually PM 2.5 levels to rebound into the moderate category. The next frontal system, slated to pass through late next week, will provide more rain and a reduction in air quality concentrations across the area. --Nolan
