Here's a link to the rudimentary map of snowfall thru 84 hrs on the 18z GGEM. The totals are in millimeters, so multiply your color coded area by .4 to get approximate qpf in inches, if you didn't know. It does not account for ratios,just qpf as snow. Snow is over by the end of the run.
If you change the model run on the upper right, you can compare changes from 12z and a few earlier runs. You can also change the precip types for ip or zr on the left side.

Fair point, but Euro did come north at 12z from its 6z run, so it may have already reached bottom and is on its way back. Idk. I guess we'll see shortly. Lol
Well, from this 18z forecast today and when the first flakes are supposed to start falling, it's 2.5 days. So from that perspective, it is certainly possible.
Not that I disagree, but would add that it is common for there to be pretty sharp cutoffs due to confluence. None sharper to what I witnessed on the 1/3/22 storm that missed all of PA. I think ur familiar with 795 off the Baltimore beltway. When I went to work in Glen Burnie the day after, there was a thin coating at the end of 795 where it hits Rt. 140. By the time I got to the Beltway, there was 3", and then 7" in Glen Burnie. That was a brutal cutoff that had the storm been bigger, may have rivaled 2010...I say may.
I'm hoping. Eps, like the operational, did increase qpf from the 6z, so that "seems" to be the bottom...hopefully. If we can can at least add .1", preferably more, over the next 2 and half days, my hope of at least 6" should be distinctly possible.
