Forecast Discussion: Current conditions: Clouds with a few sunny breaks this Monday afternoon as low pressure currently well off the New Jersey coast moves further to the northeast. A light north to northwesterly wind is acting to keep fine particulate mostly in the good range. Tonight will be mostly cloudy with just a little drizzle as lows fall back into the middle 30s. *** Tuesday's forecast: Calm winds along with a weak inversion Tuesday morning as well as very little afternoon mixing will result in fine particulate values climbing well into the moderate range Tuesday. A few sunny breaks will aid in boosting temperatures into the lower 50s. *** Extended forecast: Northwest winds will strengthen some later Wednesday as an area of high pressure builds in from the Midwest, but these might not be enough to keep PM2.5 out of the moderate range. High pressure moves off to the east by Thursday, shifting winds into the southwest and bringing in a little milder air, then the next cold front moves through late Friday with a chance for showers. Thursday's air quality may remain moderate, but lower concentrations are likely with the frontal passage on Friday.---McAuliffe
