Fort Meade

Weak southerly flow will be felt across the area Tuesday as high pressure positions itself off the Mid-Atlantic coast. Unseasonal warmth and ample sunshine will help to push ozone concentrations into threshold Good to low Moderate. Clouds will be on the increase Wednesday as a low pressure and associated cold front push through the state. Winds will also turn quite breezy during the afternoon, helping to lower ozone concentrations back into the Good AQI range across the state. Clean and cool Canadian air will usher in behind the passing front Thursday. Despite some sunshine, expect Good air quality to persist given sufficient mixing and unseasonably cool temperatures. –MDE
