Forecast Discussion: Temperatures climbing in to the low 90s and sunshine through the mid afternoon will combine to raise ozone concentrations into the middle and upper Moderate range in the I-95 corridor on Wednesday. A few locations, particularly northeast of Baltimore, may flirt with Unhealthy for Sensitive Groups (USG) air quality. However, widespread USG conditions are not anticipated, resulting in an upper Moderate AQI forecast. A cold front will bring rain and clouds and eventually slightly cooler, drier, and cleaner air on Thursday and Friday leading to generally Good air quality. - MDE
