🌤️ Delmarva Weather Update — Sunday, July 12, 2026
Coastal Flood Advisories and Statements in effect this evening for Delaware and lower Eastern Shore tidal areas through late tonight.
Today's Weather Story: A quiet, seasonable Sunday for most of Delmarva, with a clear north-to-south split. Northern Delaware stays mostly sunny and dry under light east winds, while shower and thunderstorm chances tick up across the lower Eastern Shore and Virginia coast as moisture pools closer to a stalled boundary offshore. Onshore flow keeps the Atlantic beaches noticeably cooler than points inland.
Across Delmarva:
- Wilmington, DE — Mostly Sunny, high 86°F, wind 5 mph E
- Dover, DE — Partly Sunny, high 83°F, wind 5 to 10 mph E
- Georgetown, DE — Partly Sunny, high 82°F, wind 5 to 10 mph E
- Lewes, DE — Partly Sunny, high 84°F, wind 10 to 15 mph E
- Cambridge, MD — Slight Chance Showers and Thunderstorms, high 84°F, wind 7 to 12 mph E
- Salisbury, MD — Slight Chance Showers and Thunderstorms, high 83°F, wind 6 to 12 mph E

- Chincoteague, VA — Chance Showers and Thunderstorms then Mostly Cloudy, high 79°F, wind 9 to 16 mph E
Active Weather Alerts:
- Coastal Flood Advisory — Kent, Inland Sussex, Delaware Beaches until 11:00 PM EDT tonight

- Coastal Flood Statement — Dorchester, Wicomico, Somerset, Accomack, Northampton until 1:00 AM EDT
Severe Weather Outlook: SPC has a General Thunderstorms risk today reaching the Cape Charles, VA area — no categorical severe risk over Delmarva. WPC flags localized flooding potential with locally heavy rainfall and totals up to 3–5" possible in the wettest storms, an outlook most relevant to the southern Eastern Shore and Virginia coast where PoPs are highest. Northern and central Delaware stay largely out of that heavy-rain window.
Why This Setup: A stalled boundary and tropical moisture feed sit close enough to the lower Delmarva to fire scattered storms, while an onshore east flow keeps the north drier and mild. It's a classic split — coast wins the clouds, the interior north wins the sun.
Looking Ahead: Scattered shower and thunderstorm chances linger into Monday before a warming trend takes over Tuesday, with above-normal temperatures — and possible heat headlines by Wednesday — building through the week.
Bottom Line: Enjoy a pleasant Delaware Sunday; if you're headed to Ocean City, Chincoteague, or the lower Shore, pack the rain jacket and mind the evening high tide.
