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.
Wednesday: An unsettled weather pattern will remain in place to continue the partly to mostly cloudy skies and high chance for scattered storms. Winds will be southerly at 5-15 mph. PM2.5 and Ozone are both expected to be in the green (good) range of the AQI.
Thursday-Friday: Troughing to the west of the area will finally move eastward and across the area. This will lead to a high chance for scattered storms. Ridging will build into the area on Friday and will create mostly sunny skies with a very low chance for storms. PM2.5 is expected to be in the green range on Thursday and in the yellow range on Friday. Ozone is expected to be in the green range on Thursday and Friday.
