Probably going to be a couple 18"+ reports out of the Catoctins and 12"+ out of the upper portions of Frederick, Carroll, Baltimore, and Harford counties.
As the coastal finally strengthens it's grip and torques around, better snow rates should nudge south of I-70 in Maryland this afternoon. I know it's excruciating for a lot of folks, but patience is the only thing I can recommend.
Might be some terrain enhancement, but I could see some 12"+ amounts from northern Frederick County, especially around the Catoctins when this is all over. Radar really lighting up there.
