PIT is a very underrated city. It's a small city but still very much has that large city feel. It's a very cheap city as well.

Culturally, it has everything a city multiple times it's size would have. It's got an amazing food scene, museums, sports, entertainment, etc.
Between all the parks, rivers, lakes, you can pretty much do any type of outdoor activity.

Climate wise, summers typically are upper 70's into lower 90's. Winters aren't horrible here as it is far enough south that it does not typically receive lake effect snow storms. Winter here really is from Mid January through very early April.
