Models are still all over the place for this week which is making it really hard to do any forecast. One of the problems is a cut-off low coming down the coast this week and since they don't have anything steering them they are always a problem.
We will see temps warm back into the 30's Tuesday and Wednesday ahead of the next cold front. The cold front begins to move down the coast and stalls to our North Thursday before it is kicked inland by a storm on Friday. This storm looks pretty weak at the moment with snowfall in the 6-12 inch range at best. The cut-off low behind it now looks to dive down the coast and come in over Southern CA. There could still be some snow shower activity over the weekend.
Then the pattern gets really interesting. The storm door looks to open the middle of next week with a low setting up in the Gulf of Alaska and sending multiple storms into the West Coast. A strong Arctic jetstream now over Europe looks to possibly dive into CA by the middle of the month with a subtropical moisture feed. We could see an onslaught of storms by the end of next week and beyond. If the subtropical moisture tap sets up we could be in for snowfall amounts that make last weeks storm look small. With a warm moisture tap snowfall level would be in question. If the jetstream aims at Northern CA then we may have low elevation rain/high elevation snow. If the jet aims at Central CA or just to our South then the snow levels would be low enough for all snow.
December looks exciting. Stay tuned......BA
