I’m sorry I disagree.
Even just looking back at old ECMWF runs now, it didn’t really start showing the higher amounts until 12z yesterday, maybe you could argue 00z. Sure the GGEM was amped, but that’s a typical bias of that model so I was discounting some of those runs. The FV3 admittedly did well.
There was enough short term guidance and the good ol’ OP GFS suggesting this would not happen. I don’t think many of us were expecting the push this far north with respectable totals. Therefore for me personally, this is an overperformer.
