@RJohnson The source of temperature isolines is the same as the one used to draw the colored layer for temperature and to display the local temperature in the weather picker. But the method used by Windy to draw these isotherms tends to smooth them out. So they are more useful on a large scale. In addition, at a local scale you must take into account the resolution of the model which does not allow for sufficient granularity, for example in mountainous areas.

@rjohnson Hello, what setup do you mean please? The only options that can be saved are located in Settings. Anything else will not be saved.

@rjohnson Hi, thank you for report. We will investigate it.
