It's remarkable that every CAM has a forced line of convection tomorrow morning arriving on the west side of DC around 7AM and hitting the eastern side around 8.   I'm also very intrigued by all CAMs showing a broken line on the secondary front in the early afternoon.   This environment will have some CAPE and some low freezing levels, so I suspect that these could be accompanied by small hail or graupel.

      Same here!    As for the overnight rainfall, a bunch of HRRR cycles late yesterday showed a significant minimum in the precip for most of the area.   I dismissed it, because it really didn't fit the narrative, but it was spot on.
