oh yeah, i know all about case. it's a great school. I considered applying there, but I too knew that i need a change from the midwest. I only applied to 1 ohio school just to appease my parents.
i read on wikipedia or something that the rockies to the east help to block the arctic breeze, thus keeping it from being really cold. so if you can handle some snow in the high 20s then you can manage. since you are from indiana i am assuming you know all about frigid temperatures
this probably won't be a big deal to you.
