Models hinting at another big trough in a week or so

SEA is seeing 25 mph SSW gusts now and should be calm tonight. It'll also be nighttime. Precip rate will be vital but it's not like that's the only reason it'll be colder than right now.

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.
