Tomer’s Take: Current storm cycle lasts through 2/12 then high pressure builds. Next storm system is hitting CA with a moderate/strong atmospheric river (AR) surge 2/4-2/5. Then this storm system breaks loose 2/5-2/8 and hits UT/ID/WY/MT/CO/NM with heavy snow accumulation. A smaller storm system 2/8-2/9 races into UT/AZ/CO/NM and meshes with the prior storm system and keeps the snow going. Another small storm system 2/10-2/12 takes a northern track and moves through BC/MT/ID/WY/UT/CO with light to moderate snow accumulation.
My afternoon forecast video update:
Current Setup

Central CA Radar 2/4 at 3:45pm:
Water vapor satellite shows the storm system off the CA coast. The other storm system will curve into AK/Canada and eventually send energy south into the United States.
Orange/red = drier air aloft.
Forecast Jet Stream
Powerful moisture transport into CA and optimized Subtropical jet stream orientation.
