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: *** Saturday’s Forecast: Warm and humid conditions on Saturday will feel more like middle of the summer weather than late April. Temperatures will climb well into the 80s under a mix of sun and clouds. While conditions will be similar to what we typically see as favorable for moderate levels of PM-2.5 concentrations (i.e., light southwesterly breeze), the amount of moisture present will be too high in that it will limit peak levels for the day to occurring during the morning hours when we will see the most stable conditions. Scattered showers and thunderstorms developing in the afternoon will provide moderate to heavy rainfall to only further limit any rise in values over the course of the day. Therefore, with just a few hours of higher concentrations during the morning hours before improving for the remainder of the day, PM-2.5 concentrations will mostly sit inside the good range. *** Sunday’s Forecast: Chances for showers will continue into early Sunday before those chances decrease by the afternoon to evening hours. Temperatures will be a bit cooler than Saturday, partially due to a change in wind flow to being more easterly for the day. The easterly flow will help PM-2.5 concentrations stay inside the higher end of the good range. Maximum temperatures may be set just after midnight for some locations as temperatures during the afternoon will be lower than the 70s, ranging from the mid 50s to mid 60s from east to west across the region. *** Monday’s Forecast: Southerly flow returns early on Monday, bumping temperatures back into the 70s during the afternoon hours. After a weekend of PM-2.5 concentrations in the higher end of the good range, we should see a rise just enough to hit the low end of the moderate range. Chances for showers and thunderstorms will return during the afternoon with a cold front arriving late Monday to early Tuesday. *** Extended Outlook: After the frontal passage by early Tuesday, much drier and slightly cooler than normal temperatures will prevail for the remainder of the week. Breezy conditions will provide ample mixing to keep PM-2.5 concentrations inside the good range. Daily highs will be in the 60s, which is just below what is considered normal for daily maximums in early May. --- Roble
