Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, a weakening frontal boundary was located to our west, and slowly drifting southeastward. With a light wind flow, fine particulate remained in the moderate range. A strong ridge of high pressure will slowly build over the area over the next several days, keeping summer going, even as the calendar says fall will arrive by Friday. For tonight, there will be a shower or thundershower south of Pittsburgh early this evening, otherwise tonight will be clear to partly cloudy with areas of fog late. *** Wednesday's forecast: Periods of clouds and sunshine on Wednesday with a warm afternoon. Light winds will again allow PM2.5 values to go to the lower moderate range. A shower is again possible in spots south of Pittsburgh. Afternoon temperatures will top out around the 80 degree mark. Clear to partly cloudy and mild Wednesday night with lows in the lower 60s. *** Extended forecast: A ridge of high pressure, both at the surface and aloft, will continue to control the weather later this week on into the weekend with mostly sunny skies and unseasonably warm air. Limited mixing will maintain moderately high levels of PM2.5, and ozone will even have to be watched for signs of spiking to moderate levels over the next several days with the sunshine and unseasonable heat.---McAuliffe
