@Bubbler86 - update from Elliott at MU tonight...kudos to you, you've been all over this for days:
Smaller-scale disturbances rotating around the base of the trough will interact w/a pocket of cold air aloft to produce another brisk, chilly & unsettled weekend in the mid-Atlantic. In fact, graupel or snowflakes may yet again mix in w/scattered showers across the region.
