AQI: Good (0 - 50) AQI: Good (0 - 50)
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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Current Conditions: As of 2 PM on Friday, overcast skies prevail over the region as a cold front continues to press east through the Ohio Valley. The difference between this cold front and the few preceding it is that the remnants of Tropical Storm Cindy, which contributed to 10+ inch rainfall amounts across portions of the deep South, will be funneling northward ahead of the front. As a result, expect heavy rain for periods of tonight until the front clears the region (which is why there is a Flash Flood Watch until Saturday at 2 AM). Right now, rain continues to fall across portions of the region as temperatures climb into the low to mid 70s. The cloud cover and rain continues to limit air quality to the good range today. Expect good air quality to persist through the weekend as cooler, drier conditions make their way into the region. Now onto the day-to-day details... *** On Saturday, mostly cloudy skies early in the day will give way to partial sunshine late as higher pressure begins to build in behind the departing frontal system. The additional afternoon sunshine will allow temperatures to reach the 80 degree mark. Westerly winds will also begin to usher in a drier air mass. As a result, ozone and PM 2.5 levels will remain confined to the good range. *** For Sunday, expect mostly sunny skies to persist over the region as an area of high pressure continues to build east across the northern Plains. This high will keep our winds out of the west, northwest. This flow will, in turn, allow an influx of cooler, drier air into the area. So as temperatures extend into the low 70s during the afternoon, expect ozone and PM 2.5 levels to stay within the good threshold. *** On Monday, we will continue to see partly sunny skies in the morning as the high pressure system, which was over the northern Plains on Sunday, continues to slowly progress east. At the same time, a weak storm system will criss-cross the Great Lakes, possibly triggering some light shower activity during the afternoon / evening hours. Overall, the additional afternoon cloud cover and rain chances will not only limit afternoon peaks to the upper 60s but will also keep ozone and PM 2.5 levels within the good category. *** Extended Outlook: As we take a peek into next week, we notice that the air quality will start off in the good range thanks to a slow progression of a high pressure system from the west and a weak disturbance residing over the Great Lakes region on Monday. By the middle of the week, the area of high pressure that was to our west during the weekend will have progressed east and over the Mid-Atlantic. As a result, expect clearer skies and temperatures to begin to rebound. By Thursday, this high will be moving into the Atlantic as another cold front begins to move into the Midwest. The actual front will then become stalled off to our west as the first area of low pressure (which initially drove the front into the Midwest) moves out to sea and a secondary low develops across the central Plains. It is this low that will help to push the front through our area later next weekend. Overall, after residing in the good range for a good portion of the beginning of the week, air quality levels are likely to rebound as the heat and humidity returns (on Thursday into Friday). Ozone is likely to be highest on Thursday because of the lack of clouds. As clouds return Friday and stick around through the weekend, expect ozone to fall. This is the time PM 2.5 will begin to thrive, rising through the moderate range thanks to the increased humidity over the area ahead of the cold front passage. --Nolan
