Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
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.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Current conditions: Very nice weather continues across the region this Friday afternoon, as high pressure remains centered over the eastern Ohio valley. This high will move slowly to the east over the weekend, continuing the stretch of mild and dry conditions. Northwesterly mixing is bringing fine particulate down into the good range in many locations this afternoon. Tonight will be another mostly clear night, with low temperatures falling to the middle 40s. *** Saturday's forecast: A spectacularly sunny day is in store for Saturday. With winds rather light and mixing limited, PM2.5 will rise some, but the presence of dry air should keep this pollutant at the top end of the good range. Afternoon temperatures will top out in the middle 70s. *** Sunday's forecast: Lots of sunshine will continue into the day Sunday with a very nice afternoon. A little stronger mixing from the south and southeast may keep fine particulate levels in the upper good range again. *** Monday's forecast: Sunshine will be followed by clouds to start the work week on Monday. An increasing onshore flow will bring in cleaner maritime air, so fine particulate concentrations improve further down into the good range. *** Extended forecast: A strong cold front moving through on Tuesday will bring a round of heavier rain and perhaps a thunderstorm, then cooler and more seasonable air will sweep in behind the front on west to northwest winds Wednesday into Thursday. Strong low level mixing will insure good air quality during the mid week period.---McAuliffe
