As far as weather goes, this is a different story. As a native of Wisconsin, I've seen a lot of snow. But the most snow I've ever seen in my life was the time I visited Tahoe in March. The night before, we had put out the wiper blades...pointing straight out away from the car so they wouldn't freeze. The next morning there was so much snow that even the wiper blades pointing straight out were covered completely.

There are flash flood warnings in Napa county. But those would likely be in valley areas. In any case, it is pretty windy and rainy out there. But I'm not so worried about the weather itself as I am about the other drivers.
