Here is the second video Dean uploaded from last night and early this morning in Mt. Shasta City, CA when a very heavy snow band was moving in. The rain/snow line was a little higher than forecast today, resulting in rain/snow mix as the predominate precipitation type, so accumulations in Mt. Shasta were limited to 6-8 inches. However, 1-3 feet are still possible at Dean's location as the vorticity maximum moves over head and snow levels lower substantially. Thundersnow is a definite possibility as the cold air aloft moves overhead.
Further south in the central Sierra Nevada Mountains, very heavy snow has been falling all day today, with wind gusts of over 100 mph reported at several locations. As much as 10 feet of snow is even possible at the higher elevations before the storm is over! The snow drifts resulting from these conditions would be incredible. Stay tuned for more updates!
