The highest AQ index in Maryland (as of 13:00 EDT) is currently the Upper Eastern Shore area. Particle Pollution (PM2.5) is measuring at 55 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Lower Eastern Shore area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Hot conditions on Thursday will be offset by strong winds, clouds, and the possibility of storms leading to a Good AQI day, despite the heat. A cold front will work its way through on Friday, but not before another day of warmth may lead to threshold Good/Moderate AQI due to ozone in a few areas. Good AQI continues to dominate, however. Good AQI is currently expected for Saturday. For the latest air quality information, please visit our website here. -MDE
