Forecast Discussion: Current conditions: East to southeast winds have increased across the Delaware Valley this Friday afternoon, and this will mean overall fine particulate values will remain in the moderate range today. Clouds will increase and thicken tonight, with rain arriving towards morning. *** Saturday's forecast: Rain will fall, heavy at times Saturday morning into the early afternoon before tapering to showers. The rainfall intensity will act to clean things out to where air quality is good for a change. Turning out partly cloudy, but not too cold Saturday night. *** Sunday's forecast: Breezy Sunday with periods of clouds and sunshine and temperatures remaining above normal. Strong low level mixing will retain low levels of particles. *** Monday's forecast: Just a little cooler on Monday with more clouds than sunshine, but enough mixing will persist for good air quality. *** Extended forecast: The next cold front arrives during the mid week period, and a northerly flow behind it might send temperatures back down towards normal late in the week, with good air quality continuing.---McAuliffe
