Severe Weather Outlook: SPC places Wilmington, Dover, Lewes, Ocean City, Salisbury, and Chincoteague in a Slight Risk today. That risk is notably higher than the limited shower chances in the point forecasts, so most areas may remain dry while any storm that does form warrants attention. WPC does not indicate a Delmarva-specific excessive rainfall risk.
Why This Setup: A shortwave trough moving through today could provide enough lift for isolated showers or storms, but relatively stable air near the surface should limit coverage. Onshore flow and a nearby stalled boundary remain part of the larger pattern.
Looking Ahead: Thursday turns hot and humid, with unsettled conditions and the potential for severe thunderstorms. Scattered thunderstorms are possible again Friday, mainly south of Philadelphia.
Bottom Line: Plan for fog early and a mostly dry, seasonably warm afternoon, but keep an eye on the sky for an isolated shower or thunderstorm.
