Greetings!

I think, based on the warning, that the `cape` variable you're trying to plot 
has more than a single time dimension, which is creating a little bit of 
havok--in either xarray or metpy. Can you send the code you're using to read in 
`ds`, as well as the full error traceback you're seeing? What you included so 
far, while helpful, only includes a *warning*, not the actual error. Then we 
can get you sorted out.

Cheers!
