Current Conditions at 3 PM EDT this Wednesday afternoon: Skies are partly sunny across the region with showers and thunder developing across areas south of Pittsburgh. Fine particle (PM2.5) concentrations remain solidly in the moderate range, while ozone is also rising to lower moderate. A series of weather systems affecting the area Thursday and Friday will elevate shower and thunderstorm chances. Here are the forecast details: *** Thursday’s forecast: Times of clouds and sunshine with mainly afternoon and evening thunderstorms developing Thursday. Ozone will be limited to only the lower moderate range, with higher humidity, less mixing, and light southwest winds leading to moderate concentrations of PM2.5. *** Extended forecast: Mostly cloudy Friday with showers and thunderstorms likely as highs remain near 80. Ozone will stay in the good range with cloud cover and rainfall, but PM2.5 will still average moderate. High pressure will slowly build in over the weekend, but with still the chance for an isolated thundershower Saturday. Air quality over the weekend in the high good to lower moderate range. We will continue to monitor the southward progression of any wildfire smoke from eastern Canada over the weekend as well.---McAuliffe
