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.
Thursday: A cold front will move through the area on Wednesday night with rain ending before dawn. High pressure will build into the area behind the front and will decrease cloud cover the rest of the day. Winds will be from the northwest at 10-15 mph. PM2.5 is expected to remain in the green (good) range of the AQI.
Friday: Surface high pressure centered over the middle Mississippi River Valley will move eastward over the course of the day. This will provide mostly sunny skies during the daytime. Winds at 5-15 mph will switch from the northeast to southeast with the movement of the high. A surface low will develop in the Plains and begin to move eastward and will lead to an increase in clouds during the evening. PM2.5 is expected to rise into the yellow range.
