Oh sorry -- I'm in far northern Baltimore county, about 5 miles south of the PA line. Have some elevation too, which is helpful.
850s aren't too much of an issue, but the surface will be the issue. Could see it starting as snow for most (except Eastern Shore and far southern MD), but not accumulating where it's 33 or so at the surface. Places north and west will hang on to the cold a bit longer, and with heavy precip, it will snow even if it doesn't amount to much. It's most likely going to be a real-time event where every degree makes a difference on what is falling and what is accumulating.
