The latest weather forecast in Baltimore/Washington predicts that the low-pressure system currently lingering off the Mid-Atlantic coast will give way to high pressure from the north through Saturday. For Baltimore and its vicinities, this means that while the threat of isolated light showers and patches of drizzle could stick around through the morning, clearer skies and mild temperatures in the mid-70s to lower 80s are expected by the afternoon.
