Severe Weather Outlook: SPC places much of Delmarva in a General Thunderstorms Risk today, including Wilmington, Dover, Lewes, Salisbury, Ocean City, Chincoteague, and Cape Charles; no categorical severe-weather risk is indicated. WPC guidance flags a possible excessive-rainfall/flooding concern for Delmarva, mainly as showers and thunderstorms increase tonight into the next period.
Why This Setup: A warm front and nearby low pressure will lift moisture toward the region, while a stalled boundary helps focus showers and thunderstorms later. The more organized wet-weather setup holds off through much of the daytime period, allowing most locations to stay mostly dry today.
Looking Ahead: Low pressure moves through tonight into Sunday morning, bringing showers and thunderstorms and a localized heavy-rain/flash-flood risk for portions of the region. A cold front follows late Sunday, with mainly dry, seasonable conditions expected Monday through Wednesday.
Bottom Line: Enjoy the mostly dry and comfortably warm Saturday, but plan for wetter, more unsettled conditions arriving tonight.
