Ahhh the Kuchera ratio lol. That's a good question! My answer is no one model individually, though I do have a preferred model forecast for snow called positive snow depth change, or PSDC.

PSDC accounts for surface temperature, snow growth, precipitation types, compaction, etc. to provide a more realistic representation of how much snow a person will measure. When you compare the 12Z HRRR Kuchera & PSDC data, it should become immediately apparent that there's a notable difference in the Lakes Region where above-freezing air may surge all the way north to. The snow ratios in the White Mountains north of this heavy snow band will be pretty impressive, I can easily see 12-16" above 1,500 feet
