I had just over 5" I think now looking back. That was when everyone in my fam was sick and I had pneumonia so I didn't know what the hell was happening..lol.
You can see it at 700. I was playing around with the H7 winds and there is a nice jet there into PA. That weakens and then the offshore one takes over like you said. So the precip sort of shrivels up as it moves east before re-developing to the south.
Yeah they aren't really flagging a big surprise quite yet. RAP always seems to be too far NW after hr 18 or so and that is borderline to like the canal for larger stuff right now.
