Air Quality Forecast

Air quality forecasts are issued every day of the year for the Birmingham area and are based on the Air Quality Index (AQI).  The AQI is a color-coded scale that reports how clean or polluted the air is and the associated health effects.

The Jefferson County Department of Health forecasts fine particles (PM2.5) year-round and the Alabama Department of Environmental Management forecasts Ozone (O3) during the warm season.

An Air Quality Alert is issued when the AQI is forecast to reach 101 or higher.  The public is encouraged to decrease their personal emissions on days with higher pollution levels.

Forecast Discussion



Thursday: A weak frontal boundary will move through the area from the north. Winds will be from the north to northeast at 5-10 mph. The northerly flow and passage of the front will decrease moisture levels, which will decrease the cloud cover somewhat and drop the chance for rainfall. High temperatures will increase to the upper 80s. Both PM2.5 and Ozone are expected to rise into the yellow range. ML

Friday: The area will return to a weather set up with a southerly stream of moisture into the area. This will create mostly cloudy to overcast skies all day long with scattered showers and storms throughout the day. High temperatures will be in the mid 80s. PM2.5 and Ozone are expected to be in the green range. ML
