If I'm reading 18z GFS ZR maps on pivotal right, that's close to half an inch of freezing rain in a band from Cecil County through Harford and Baltimore, down into Howard and Montgomery Counties (also further inland in Carroll/Frederick). I know consensus is still missing so we're still low confidence, but the GFS really does not want to budge. I'm sure there are some considerations around using the "ice clown maps" to gauge real world impact as with snow (and I'd love to hear more about them from red taggers or others knowledgeable), but yikes, no thanks.
