A lot more snow to come for CA/OR and the towards the 4 Corners and Rockies, plus there will even be snow down to about 1000' in the CA valleys and even a bit of snow down to the coast in NoCal and OR, which is very unusual.
A prolonged major winter storm will continue to bring widespread heavy snow and blizzard conditions to portions of the West as well as the northern Plains/Great Lakes into Thursday as a series of low pressure waves traverse a front to the south. Heavy snowfall rates of as much as 1 to 2 inches/hour are expected to combine with winds locally as high as 40 to 50 mph to drive significant impacts that will include major disruptions to travel, infrastructure, livestock and recreation. This series of low pressure waves that will make up this coast-to-coast winter storm will bring heavy snow and locally significant ice from the Great Lakes into the Northeast, and many of these areas are expected to see an additional 6 to 12 inches of snow, with some amounts perhaps as high as 18 inches. Power outages and areas of tree damage will be possible across these areas, and especially for the locations seeing a combination of stronger winds and accumulating ice.
On Thursday and Friday, the heavy snowfall threat across the West should become more centered over California as a new storm system developing just off the West Coast drops south and begins to edge into the Southwest for the end of the week. Multiple rounds of new snowfall should accumulate to as much as 3 to 5 feet for the Sierra Nevada, with locally heavier totals for the highest peaks. Lesser amounts of 1 to 2 feet are forecast elsewhere across portions of the Great Basin and into the Four Corners region. Given the depth of cold air that has infiltrated the West, accumulating snow will also be expected over some of the lower foothills and interior valley areas near the Pacific Coast adjacent to the terrain where snowfall is less common. Onshore flow combined with instability related to the cold pool aloft will lead to a heightened risk of flash flooding across southern California Friday morning into Saturday.

Our Monday night/Tuesday system is looking like it may at least deliver a few inches of snow along and N of 80 (and maybe several inches N of 80) and possibly even down to 78 and maybe to the Raritan (more likely mostly/all rain south of 78 though). If we start to see some model consensus by tomorrow (models are all over the place right now, 4-5 days out), would likely be worth a thread, even if it's all/mostly rain for CNJ as quite a few posters live in NNJ/NEPA/NYC/LI.
Also, keep in mind most of the area might see a coating to 1/2" on Saturday, but there might also be nothing as predicting that little precip accurately (+/- 1/2" means zero for everyone on the minus side) is very difficult.
And 3/4 is looking like the best chance this winter for some decent snow for everyone, but it's 9 days out, so that chance could easily fall apart (but we haven't even been seeing fantasy storms 9 days out in this warm winter, so it's worth watching).
