Forecast Discussion: Current Conditions: Humidity levels are on the increase across the area at 2 p.m. EDT this Monday afternoon. A cool front is presently in the dying stages across southeastern Pennsylvania. A ridge of high pressure building over us will cause the heat to build over the next couple of days, and with this, fine particulate and ozone concentrations will increase. In fact, we are keeping an eye on upwind locations to see how much ozone transport there will be over the next few days. At present, it appears as though ozone generation will be maxing out by Wednesday, when chances for code ORANGE ozone levels are highest. Tonight will be partly cloudy and humid with lows near 70 degrees. Fine particulate will be well into the moderate range. *** Tuesday's forecast: High pressure building into the area on Tuesday will allow for a good deal of sunshine, and with upper levels also warming, the chances for convection will be surpressed. Ozone will thus move well into the moderate range, with PM2.5 also into moderate territory. Afternoon temperatures will move up to around 90 degrees. Warm and sticky Tuesday night with lows in the lower 70s. *** Extended forecast: Wednesday will bring plenty of sunshine with plenty of heat and humidity. Fine particulate will remain in the moderate levels due to higher humidity and low wind speeds. Ozone production will be at it's maximum, with code ORANGE levels possible in the afternoon. Afternoon temperatures in the lower 90s. A cool front will then move in late Thursday and Thursday night. Convection out ahead of this front will reduce ozone production to the point where levels may only make the lower moderate range. A return to good overall air quality will then occur Friday into Saturday with a good deal of sunshine and drier air in the boundary layer.---McAuliffe
