Atmospheric River through 1/6

Tomer’s Take: It now looks like the atmospheric river (AR) continues through 1/6 generating feet of grand total snow across the West.

Awesome sunrise view at Palisades Tahoe this morning in-between storm systems.

The first storm system delivered 13-22 inches of snow at higher elevations with a rain/snow problem lower.
