WASHINGTON DC METRO AREA FORECAST DISCUSSION
Have raised the cloud cover forecast given the persistence of low stratus across the area. Otherwise, with tidal flooding looking more likely in Annapolis, have hoisted Coastal Flood Advisories for tonight`s high tide. Looking ahead to Tuesday night, the increase in wind around the dome of Canadian high pressure has decreased the threat for frost conditions.
