Forecast Discussion: Current Conditions: At 2 p.m. EDT this Wednesday afternoon, high pressure is in control of the weather across most of the area, but a weakening area of low pressure is bringing a thundershower to places southwest of Pittsburgh. Light winds close to the surface have allowed for buildups of PM2.5 and ozone as well. High pressure will bring sunshine for the most part with unseasonably warm afternoons into the upcoming weekend. Limited mixing along with sunshine most of the time and unseasonable warmth will bring more moderate levels of ozone, and PM2.5 concentrations may also be elevated with strong morning inversions each of the next few days. For tonight, we will have a mostly clear sky with areas of fog forming. *** Thursday's forecast: Mostly sunny skies with a rather warm afternoon for Thursday with the mercury topping out in the middle 80s. Both fine particulate and ozone will average in the moderate range as surface and upper level winds will remain light. Mostly clear and mild Thursday night with lows in the lower to middle 60s. *** Extended forecast: As we move into the official start of fall on Friday, summerlike weather will remain with us for another weekend. A strong area of high pressure, both at the surface and aloft coming in from the Ohio valley will bring sunshine with unseasonably warm afternoons. Ozone generation will be closely monitored for spikes well into the moderate range, with fine particulate continuing to average in the moderate range as well.---McAuliffe
