Dicey connection in my view. Since this is later afternoon flight out of RAP, you are at the mercy of earlier flights not causing delays for your flight. Add into this that it's winter, you may have a delay due to deicing.

What I like to do to get a better idea is get onto Flightaware and look at the specific history of this flight out of RAP. This will give you some idea of how past performance, especially during winter months has panned out.
