Forecast Discussion: Current conditions: High pressure drifting to the south and east of the area this Friday afternoon has shifted winds around into a more southwesterly direction. The southwest winds have brought us a warmer afternoon under mostly sunny skies. The air is still clean and dry enough to where fine particulate and ozone are in the good range. Tonight brings a mostly clear sky as temperatures fall back to the lower 50s. *** Saturday's forecast: Sunshine for the day Saturday with a warm afternoon, and limited mixing may bring both fine particulate and ozone to moderate levels as temperatures move into the lower 80s. *** Sunday's forecast: Sunshine but also some cloudiness Sunday with a rather warm afternoon. A shower or thundershower cannot be ruled out late in the day as temperatures soar to summer like levels on the last official day of summer (Fall arrives Monday morning at 3:50 a.m. EDT). Higher humidity and little mixing may bring ozone and fine particulate to low moderate levels once more. *** Monday's forecast: A cold front moving through later on Monday will bring a thunderstorm late in the day, and increasing cloudiness and mixing will bring back good air quality. *** Extended forecast: High pressure returns to bring sunshine and more seasonable temperatures Tuesday into Wednesday with low values and PM and ozone.---McAuliffe
