Putting aside the snow maps for a moment. All guidance has been consistent last 3-4 runs at least with very robust QPF.
Even allowing for it being a bit overdone where max qpf can sync up with best ratios and remain all snow that alone suggests some
spots see in excess of 20". Final "jackpot totals" will depend on where banding sits and pivots. Keep in mind...what goes up must come down
so you want to be in the band because the subsidence on either side will keep your totals lower.
Some favored spot can see 24-30" and I would not be surprised. Best chance I think is north of 78 and west of 287.
