I'll be driving to San Francisco from LA this coming Friday night. Weather.com has informed me that rain is forecast for pretty much the entire drive. My question is whether anyone's got feedback about which highway is more likely to be susceptible to delays in the rain. Also, is tule fog likely to form on highway 5 during a rainy period or only after the rain has stopped? I know that the 5 is extremely boring and the 101 is slightly more scenic, but since it'll be after dark, that's not important to me. All that I'm interested in is cutting back on delays and having a safe drive.
