        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?

              @gillie-0 The whole diagram shows dependency of various things depending on height and temperature. The right colored line(red ) is predicted temperature based on height. The left (blue line) shows dew point i.e. temperature at which will condense water in given height. If those two lines are in any point close to each other it will meant that at this height there will be clouds/fog, further they are apart there is smaller probability of clouds.

              Then there are two grey lines the shallower one shows how much would cool the air with height if there were no condensation (i.e. not in cloud) the steeper one shows how it would cool if condensation would occur i.e in a cloud. Now imagine you have the bag of air and you fly with it. It will cool quite fast when going up because of expansion (gases cool down when they expand) and it would cool exactly along the shallower grey line, up until you would hit dew point (the water would start to condense), and from that point it would cool along the steeper grey line.

              And that is it. Now you can predict storms;), if your bag would cool slower than the red line with height, it would get warmer relative to surroundings and warm air goes up so it would be warmer and warmer, and it would go faster and faster up and thats how storms are created, a lot of warm air goes up with all the moisture which then goes down as rain.

                @fx-eddh there are dry and moist adiabates but only two (those two grey lines)

                  Yes, we are considering switching between these "coordinate systems".

                      I "vote" for skew-T log-P !

                      Question: On the bottom line of sounding forecast,
                      the "model altitude" turns red if the difference from real alt. >200m ?

                        @gkikas-lgpz Exactly, it is warning, that in such cases the sounding can be misleading.
                        The biggest problem is in mountainous regions - like in Greece in this picture:

                          @tz ... I've only really used SkewT professionally with Stuve taking a little getting used to.

                            @aadhaar I agree with you. It is quite difficult to guess the current situation in an area in windy. There are some companies that provide current data for many locations. Windy should include this thing and display with the observation time. This would help us very much as some of the times at a particular location in windy, we see that it's raining there, whereas in reality there exists a clear sky.

                                windy already provides realtime weather observations for many locations.
                                e.g. for airports, click on the airplane symbol

                                          @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.

                                            Sounding forecast does not work for me. All I get by right clicking is the usual forecast wind SPEED for a point on Earth; no sounding forecast.
