That’s one of the main reasons the Euro isn’t on board — 0.03”/hr precip rate vs 0.07” for HRRR and 0.11”/hr for GFS (at KSEA). I think >0.1”/hr prior to sunrise is needed for sub-1000 ft snow levels.

True. But the worst Cascade snowpack winters overall were much worse for WA, so that's what I was factoring in.

The Euro has a snow depth product like that WRF one. It’s on WxBell at the bottom of the winter category. Standard snow map is based on hypothetical accumulation of flakes in the air prior to touching ground.

It will have to be all precip rate driven. 925 temp now is the same as it will be tomorrow.

Tomorrow might be the final insult of this winter.
