The highest AQ index in Maryland (as of 7:00 EDT) is currently the Metro Baltimore area. Particle Pollution (PM2.5) is measuring at 47 (Good). This means air quality is satisfactory, and air pollution poses little or no risk.
Over the next few days, the highest Ozone (OZONE) will be in the Northeast Maryland 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.
Temperatures will remain on the cooler side heading into Saturday. This along spotty shower and thunderstorm activity will help to keep ozone levels low. Good air quality is expected across the state. Temperatures are expected to rise quickly above normal heading into Sunday, and with sufficient breaks of sunshine, generally low to moderate ozone levels are anticipated along the I-95 corridor. Temperatures look to drop back to below seasonal norms for the first half of next week as a series of disturbances impact the area. Winds will also be a bit breezy over this period, helping to keep both ozone and fine particulates in the Good AQI range Monday, Tuesday and Wednesday.
