Discussion
Low pressure is going to intensify significantly this weekend near the Southeast US coastline, induced by a frontal boundary zone that slides into the region, and energized by an upper-level trough that drops southeast across the Great Lakes. It appears likely that this strong coastal storm will then push far enough to the north to have an impact on the Mid-Atlantic region all the way from later Saturday into late Monday. The worst impact will be along coastal sections where rain will be heaviest, winds will be strongest, and the threat of coastal flooding/beach erosion will be high due to a prolonged period of onshore flow.
