Iris help!

Hello, I am brand new to both this community and gardening! And I have a couple questions. :-) My sister recently gave me quite a few iris bulbs (rhizomes? that's what Google says). I have never had irises, and am not sure if it is ok to plant them now or if I need to wait. I live in northern Oklahoma and our weather has been in the mid 80s lately. Is that too hot? If it is too hot, how do I store them? She instructed me on how to plant them, but she lives in Nebraska and I live in Oklahoma, so I am not sure if she thought of that when telling me it would be ok to plant them now. Thank you so much for any advice, I am so excited to start a garden!
