Forecast Discussion: On Thursday, a weak cold front will stall south of Washington, DC and then dissipate. Light winds and mostly sunny skies will promote Moderate ozone, while a period of stagnation in the morning will help particles to linger in the Moderate range as well, with the highest concentrations expected in the western part of the state. Friday will be slightly warmer with continued mostly sunny skies and light winds, for persistent low Moderate air quality. By Saturday, sustained onshore flow will return air quality to the Good range. - MDE/PSAQFO
