@chobotnatec I didn't notice those grey lines in the beginning, thank you for the hint. However, more of them would come in handy to estimate the instability at other levels than the surface.

I am impressed by every new feature you implement but this outshines everything! Thank you very much for this tool!
For optimal forecasting performance I would appreciate an option to change the diagram type from Stüve to Skew t-log p. In addition, dry and wet adiabatic lines would be very helpful for better estimating instability (see picture below for an example). Do you plan to add these options?
