There is weakening storm moving into Northwestern CA tonight. By the time the storm reaches Tahoe it should only have enough moisture left to bring only a dusting to the mountains. It will bring some more cold air though so the snow guns are really getting a workout.
The ridge is holding strong in the Eastern Pacific holding the storm track up into Western Canada. Activity will start to pick up in the Pacific NW next week with the ridge moving East before being quickly replaced by another ridge.
That will happen several times next week allowing storms to sneak into the Northwest between each ridge.
Low pressure has been setting up over the Aleutian islands and Southern Alaska sending the jet stream underneath into Western Canada. Long-range models are suggesting that the ridge will start to retrograde West in the Pacific away from the coast the last week of the month. That would allow the low pressure and associated trough to shift into the Northeast Pacific sending the jet stream underneath into the West Coast.
The later we get into the month the more the chances increase that the pattern will shift towards a La Nina Cold PDO Winter pattern. Stay tuned....BA
