This morning’s satellite picture shows a storm system moving into the Pacific Northwest with the southern end dragging across Northern California. This is not a major precipitation producer and most of the precip will in the coastal and northern mountains, with light amounts in the Sacramento Valley and Modoc, Lassen, and Plumas counties. Snow levels will be 2,000 to 3,000 feet in the north and 4,000 feet to the south. Tuesday will be partly cloudy to partly sunny and then the clouds and wind will begin to increase Tuesday night.
The map below for Wednesday shows the cold low pressure area still off the coast of Canada with the jetstream split well out in the Pacific and the southern and northern branches coming back together just off the coast. The southern branch will merge warmer, moister air with the cold air from the northern branch. The result will be a fairly strong storm moving across Northern California late Tuesday through early Thursday. This system will bring moderate to heavy precipitation to the area and very strong south winds. Wind gusts of 45 to 50 mph are possible in the Sacramento Valley, with gusts 60 to 65 mph over the higher elevations to the north and east of the valley. Snow levels will be 3,000 to 4,000 feet in the north and 4,000 to 5,000 feet to the south in Plumas county. The northern Sacramento Valley will pick up over an inch of rain, with heavier amounts in the mountains. We will have a break between systems from midday Thursday through midday Saturday. The next storm should spread rain and snow over the area late Saturday and Sunday.
