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.
The question is whether the lower quality models are just slowly catching up. Idk, but we'll get clues once Gfs, Euro, Gem and Ukie come in over the next 2 hours.
It's a good run for most, but there is a shift south from 6z. This is total snowfall thru 78hrs on 12z vs 84hrs on 6z. Admittedly, I'm focused on the north side.
But there is more to the storm after end of run which may compensate.
