Severe Weather Outlook: SPC has no categorical severe risk over Delmarva today — expect a thoroughly quiet afternoon. The story shifts on Monday, when SPC has placed a Slight Risk over much of the region, including Dover, Lewes, Salisbury, Ocean City, Chincoteague, and Cape Charles. WPC does not indicate a specific Delmarva excessive rainfall threat for today, though heavy rain and a flooding risk are flagged for Monday in the NWS narrative.
Why This Setup: A surface ridge and dry westerly flow are suppressing moisture today, but an approaching cold front interacting with a warm front and a nearby low-pressure system will reload the atmosphere by Monday. That convergence of boundaries is the ignition point for storms and locally heavy rain to start the week.
Looking Ahead: Tonight stays dry and comfortable under mostly clear skies. Monday brings the return of showers and thunderstorms, some potentially strong to severe, along with a heavy rainfall and flooding threat — then a more summer-like, humid pattern takes over mid to late week.
Bottom Line: A picture-perfect Delmarva Sunday — get the outdoor plans in today, because Monday means business.
