A developing low pressure system is expected to bring another round of wet weather to the Delmarva region late Sunday into Monday, with rain favored across much of the area.

The latest forecast guidance shows the storm system tracking south of Delmarva as it moves along the East Coast. In recent model runs, there has been a continued shift toward a more southern and faster-moving track. This trend reduces the overall impact locally and keeps the bulk of the system’s energy offshore.
With this setup, precipitation will primarily affect the coastal plain, including areas along the Atlantic coastline and the lower Eastern Shore. Rain is expected to be the dominant precipitation type across Delmarva.

While a brief mix could occur at the very onset in isolated spots, the overall air mass in place ahead of this system is milder compared to recent storms. Temperatures leading into the event will support mainly rain, and snow is not expected to be an issue for the region.

Confidence has increased that measurable precipitation will occur, particularly closer to the coast, as forecast models continue to come into better agreement. Rainfall amounts and exact timing will continue to be refined, but the most likely window for wet conditions appears to be late Sunday through early Monday.
There remains a small amount of uncertainty. A few model solutions still suggest a slightly stronger and farther north track, which could expand precipitation coverage inland. However, the prevailing forecast favors a weaker system staying mainly to our south.
