I smell overachiever with this event for the folks that end up matching the best QPF with the best snow growth (omega). Ratios will be better than the last storm (>10:1). There was a PNS report from Altoona that had 0.8 melted out of 7.2 inches of snow (9:1) out of this last event, for imstance. We could see up to 14-15:1 further north and perhaps in the Laurels with the more standard 10-12:1 elsewhere. I bet there will be a couple spots with 6 or 7 inches within the general area wide 3-4 inches.

Any gfs nam precip amount?

Find them here: http://www.meteor.iastate.edu/~ckarsten/cobb/cobb.php?model=namm&site=kunv

Just type in your location - that's set for UNV. Also, pay attention to time on the first line to make sure the model has updated, since they have the same link for 06/18 and 00/12.

UNV is slated for around 6 on that. Not sure how good the snow ratios and precip types are with that.Seems to over do mixing.
