Greetings!

Apologies on the delayed response.

Can you confirm what version of MetPy you have installed (using `pip list`)? 
You'll want to make sure you're using MetPy 0.12.2 if you have the latest 
CartoPy 0.18, which I'm guessing you do have since you just installed. You can 
upgrade metpy with:

    pip install --upgrade metpy

Hope this helps,

Ryan
