The introduction of sleet reaching DC on the 0z Nam runs tell me a northern push "may" be coming. Closest sleet before this run was a bit north of the Potomac.
I've got brisk NW winds still. I'll be shocked if we get a jump north of consequence with this one. BUT, it will mean the boundary is further south. My hope is part 2 overperforms while it rains cats and dogs in MD.
