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.
Saturday-Monday: A frontal boundary will hover around central Alabama on Saturday to provide mostly cloudy skies and scattered showers. The base of a trough will move through the area early on Sunday to push the front well to the south of the area. A much colder and drier airmass will move into the area on Sunday and Monday as surface high pressure builds into the area. Cloud cover will decrease on Sunday with skies being clear all day long on Monday. PM2.5 is expected to be in the green (good) range through Monday.
