We're seeing ensemble means of over 12" which is almost unheard of at 36-42 hours out, as the ensembles include more than a few outliers that should bring the mean down more vs. the operational run. Ensemble means that high are a strong indicator that the op runs are higher confidence than usual.
Also, last night the UK was the outlier with not much snow NW of 95 and not much snow even SE of 95. That has changed at 12Z completely, which is a 12-20" bomb for anyone N of 276/195 (but has a sharp cutoff S of that line). Will post the whole suite of 12Z maps again after the Euro.
