They would certainly produce some rain for everyone's yards. It seems the HRRR has handled the morning batch of convection the "best". We are going to have to see what things look like around 5:00 pm or so. The action doesn't really appear to develop until it sinks south of the PA Turnpike. The latest HRRR, for example, has the line coming through the DC area around 23z to 01z. Not the greatest timing, but NW flow events usually jackpot someone.
