Severe Weather Outlook: The Storm Prediction Center has placed most of Delmarva — including Wilmington, Dover, Lewes, Salisbury, Ocean City, and Chincoteague — under a Slight Risk for severe thunderstorms today. Damaging winds are the primary threat, with locally heavy rainfall also possible where storms train over the same areas. Monday drops to a General Thunderstorms Risk, but flash flood potential increases.
Why This Setup: An approaching cold front interacting with a stalled boundary and an upper-level disturbance is the trigger — plenty of moisture, plenty of instability, and a focus for storms to develop. That same setup keeps rounds of rain in play into Monday.
Looking Ahead: Additional rounds of storms are likely Monday, with the flash flood threat ramping up as ground saturates. Temperatures ease closer to seasonal norms by early next week, though unsettled weather sticks around midweek.
Bottom Line: Hydrate and limit afternoon exertion, then keep an eye to the sky — strong storms and downpours are on the table late today.
