Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.

Forecast Discussion: Current Conditions: Chilly and damp air remains entrenched in the region this Friday afternoon. A warm front well to the southwest of the area will slowly move through the area sometime late Saturday or Saturday evening. Tonight will be overcast with a bit more rain, drizzle, and perhaps areas of fog as temperatures remain nearly steady. *** Saturday's forecast: Rather cloudy Saturday, and another round of rain is likely by the afternoon as a warm front moves closer to us. While fine particulate levels will be a little higher Saturday due to warmer air attempting to advect northeastward, concentrations will level off at the top end of the good range. *** Sunday's forecast: Additional rain is likely Saturday night into early Sunday as a cold front will pass through early Sunday afternoon. Sunday may be the warmest day of the period with temperatures moving into the middle 50s. Low level mixing should be adequate enough to keep fine particulate levels low. *** Monday's forecast: High pressure will build in from the west to finally dry things out to start the new workweek with the return of sunshine. PM2.5 levels will be on the rise again, but should remain in the upper good zone. *** Extended forecast: As high pressure moves overhead, and then off the east coast Tuesday into Wednesday, surface winds will lighten and become more southerly. These lighter winds and morning inversions may push PM into the moderate range by the middle of next week. The next precipitation producer may then move in for the latter part of the week.---McAuliffe
