Summary
A level 3 of 5 severe storm risk covers Washington, D.C., and nearby areas Saturday, with thunderstorms expected to disrupt fireworks, air travel and holiday driving across the Northeast and Mid-Atlantic.
Heat approaching or exceeding 100 degrees, combined with high humidity, is fueling storms capable of damaging downbursts above 60 mph; New York City, Philadelphia and Richmond sit in a broader level 2 risk.
A level 1 of 4 flash flood risk is also in effect Saturday because moisture-rich, slow-moving cells could flood urban and low-lying areas.
Sunday keeps a level 2 severe threat in parts of the Mid-Atlantic even as the worst heat eases, before the severe risk fades into Monday and heavier rain becomes the main concern.
Monday brings a level 2 of 4 flash flood risk for southern Pennsylvania, the Delmarva and Philadelphia, with 1 to 2 inches of rain through Wednesday and isolated 2 to 3 inches in eastern Pennsylvania and north Jersey.
