@Natalie - I'm surprised to hear Idaho is that warm. We are supposed to get up in the mid-30's tomorrow, but that is kind of freakish for January here. There is a WS thread here so maybe best to check with those folks, but I was under the impression that pretty much all winter sowed seed goes out by February at the latest. When I start them inside I use the 6-8 weeks before planting out rule. For me that isn't until the end of May, so I start my tomato seed in early April.
Good luck!
