Wednesday was another quiet day around northern California, but that will change soon... rain will be back by Friday!
Clouds moved in near the Oregon border this afternoon, but the rest of us stayed fairly sunny today. Those clouds will continue to move southward overnight, so we should see mostly cloudy skies by tomorrow... with a few showers near the Oregon border.
That plume of moisture will continue to move southward, so we should expect rain throughout northern California by Friday. This storm doesn't have too much cold air, so snow levels should hover near 5000'. Look for about 2/3" of rain near Redding, tapering down to near 1/3" near Marysville.
We'll get a break in the wet weather Saturday. A powerful jet stream in the Pacific will surge towards California by late Sunday, and Valley rain and mountain snow is on tap for Monday and Tuesday. As the moisture is forced over the Coast Range, that will create a bit of a rain-shadow effect for the Valley... so we may not see that much down here. But in both the Sierra Nevada and Coast Ranges, a LOT of rain will fall. Our primary direction for a good soaker in the Valley is from the southwest... the Coast Range is higher straight to our west, and that creates a bit of a rain-shadow for the Valley (like we'll see early next week). But it's still great news, as that rain & snow that falls in the Sierra will drain to the reservoirs, and begin to fill them!
