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.
CC loop shows the mix line collapsing really well across York and Adams counties. Should see a lot of posts here soon from the Fredick/Carroll/Baltimore/Harford posters over the next couple hours. This was really well pinged by the morning run of the NAMs and RGEM.
