Key Messages

1. Low and cold front move through the region tonight into Sunday with rain showers likely.

2. A stationary front south of the region could keep rain chances around, especially for Delmarva through mid week.

3. A closed mid-level low ejecting from the Ohio Valley could help to spin up surface low pressure off our coast by Thursday, potentially bringing another chance for rain, and increasing the risk for coastal flooding.&&
