I suppose it ultimately doesn't seem to matter -- you can see it's having difficulty resolving the exact placement of the low. As others have noted, this outcome seems pretty locked regardless of exactly where the model decides the SLP is. It's looked like this for 2 days straight in one form or another.
From my limited years down there, that does appear to be true. I guess on the positive side for winter wx, I'd expect the CAD to hold on a bit longer. Could be pretty icy.
Actually, the culprit is fairly clear -- DC and close burbs get dryslotted hard for 6 hours in the peak of the storm.
edit: that said, ICON isn't gonna nail anything like that from this range. the low track is better, all that should be noted.
per the weather.us maps, the RA/SN/IP line goes right up 95. Depth map so hardly perfect, but for fun until we get the better maps. Slightly surprised its not better around DC.
loses them at 114 though, but it's close. Would take a jog ~50mi east, maybe less.
way gone at 117, that's harder to fix lmao. but as mentioned, fine at 120.
