The highest AQ index in Maryland (as of 23:00 EST) is currently the Suburban DC area. Particle Pollution (PM2.5) is measuring at 53 (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 Particle Pollution (PM2.5) will be in the Metro Baltimore 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.
Light snow is forecast for mid and southern parts of Maryland Friday. The light snowfall in concert with light winds will limit dispersion of pollutants. Furthermore, evening wood burning may further contribute to fine particle concentrations where woods stoves are prevalent. Weak dispersion and/or localized stagnation will continue to trap pollutants into Saturday, leading to ongoing Moderate AQI for the daily average concentration exposure. Little airmass change is expected going into Sunday, leading to persisting elevated concentrations of fine particles and a Moderate AQI forecast.
