Tomer’s Take: Data continues to suggest a “strong to extreme” intensity atmospheric river (AR) 12/27-1/4 for most of the West. Grand totals (see below) of 1-5 feet or more.
My forecast video 12/26:
Current Setup
Water vapor satellite shows the organizing atmospheric river reaching all the way into the western Pacific. This is the Pineapple Express.

Forecast Pattern
Forecast jet stream valid 12/30. Very impressive west to east jet stream pattern acting like a conveyor belt for the moisture. The jet reaches west beyond Hawaii.

Forecast Timing
Forecast radar/satellite valid 12/26-12/31.
Forecast Totals
Forecast snow totals (inches) valid 12/26-12/28.
