Here's Detroit's 7-day. (hopefully the copy and paste works for you) Sunday's low is 34, just like your Thursday low.

 

I'll definately come back and let you know how my 87 SS will handle this winter since my beater plans fell through... I went ahead and did all the "proper" prep work. I had the monte up in the air all week. I POR15 the whole under carriage, the frame, floors, engine cradle, sway bar, suspension, rear end, gas tank, pretyy much anything thatll even see snow. I how ever will be garage keeping it so its going to get rinsed at least 2x a week and go in the garage as much as possible.
