Heh yea, in fact I'm gonna go to the midsize so I can fit towo tubes, and definitely ziploc the minitool and tubes to keep them dry. Flats can be an issue with wet roads. Food's no problem: there are checkpoints/rest stops every 40 mi or so, where I can refill my gel flask and load the waterbottles with Sustained Energy. Its gonna be a liquid diet day tomorrow.

I had a headband on over my ears (that's something you might consider as well), a neck gaiter, ski gloves, thin socks, heavy wool knee-length socks, shoes, and neoprene booties. When the temperature finally made it to 50 degrees, I removed the neck gaiter, put on lighter gloves, and unzipped my jacket. And that's what I was comfortable in!!
Wow. On early morning rides I've been going out when the temperature's around 40 (it does warm up significantly from there) with just mesh tank top base/jersey/shorts/arm warmers. That sounds like what I would wear to go skiing, except I don't really have a clear idea of what knickers are

.
The only thing that always gets uncomfortably cold is my fingers. I got some long fingered gloves but I'm afraid they're too heavy duty. I really should pick up glove liners... Now the forecast is just 40-50% for showers. Although traveling over 200 miles gives lots of room for weather variation. I guess I'll see tomorrow morning.
Thanks everyone for your input! I'll let you know how it goes.
