and if I might add to it, to put into simpler terms, its a blend between best thermals (best snow growth is aoa -10 isotherm)....BUT....you also need best lift/qpf to help achieve, so just because you have one, doesn't mean you have the other, but its the closest point/axis between the 2 that you likely see the best totals.
Mag/taggers/anyone feel free to tweak my statement if needed.
