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.
As an OEM in Montgomery, the difference between upper and lower portions of the county is insane. I've seen even where inside the beltway it's nothing and north of Germantown it's pounding big time.
Yup. The returns working SW from Lancaster and Chester Counties and that would help cool the column off more and starting flipping people back to snow.
