Severe Weather Outlook: SPC places Wilmington in a Marginal Risk for severe weather today. Elsewhere, rain and storm chances remain isolated to scattered, highest toward the coast and lower Eastern Shore. WPC indicates a possible excessive-rainfall and flooding concern for Delmarva, but today’s point forecasts favor generally low rain chances across much of the region.
Why This Setup: An approaching cold front, nearby low pressure, and an upper-level disturbance are keeping a weak shower-and-storm signal in place. However, drier air is limiting coverage for many inland locations, with the coast holding the better rain chance.
Looking Ahead: Additional rounds of showers and storms are possible through Friday, with the highest chances Friday afternoon into Friday night as a cold front approaches. Cooler, drier weather follows for the weekend.
Bottom Line: Plan on a mostly dry, warm Wednesday for much of Delmarva, but keep an eye on the sky near the coast and allow extra caution around evening high tides in Delaware.
