Forecast Discussion: Light westerly winds and partly sunny conditions will foster ozone production Sunday, though lower weekend emissions will help to limit overall regional concentrations. Even still, a few areas, particularly the Chesapeake Bay coastline near and southeast of Baltimore City may flirt with USG conditions. Real-time alerts will be issued if necessary, but otherwise Moderate air quality is forecast on Sunday. On Monday, an approaching cold front will be slow to pass through the region. Areas of rain and clouds are possible, but wide spread coverage is not currently anticipated, thus, the slow moving front will support quickly rising ozone with added weekday emissions. Threshold USG is forecast for Baltimore, with upper Moderate elsewhere along the I-95 corridor. Lower concentrations are expected away from the Bay and I-95 corridor. Northerly winds on Tuesday along with cooler temperatures will keep ozone in check. Moderate AQI is forecast. -MDE
