Severe Weather Outlook: SPC shows no categorical severe-weather risk over Delmarva today or Thursday. WPC does not identify a Delmarva-specific excessive rainfall risk; the primary concern is coastal and tidal flooding rather than a widespread inland flash-flood setup.
Why This Setup: A strengthening coastal low is maintaining strong northeast-to-north flow and cooler air across the region. That onshore wind is driving rain into southern and coastal areas while piling water toward tidal waterways and beaches.
Looking Ahead: Rain chances gradually shift east Thursday, though gusty northeast winds persist. A drier finish to the week is possible after that.
Bottom Line: Plan for a cool, windy, damp day—especially south and near the coast—and take tidal flooding and beach hazards seriously.
