      CAPE is a measure of instability.
      However, instablility on it's own is not enough to ensure thunderstorms.
      There needs to be a lifting factor due to orography or frontal activity.
      Check for other hints such as high humidity and a forecast of showers in the area.

          Yes Rain accumulation is in inches, even if you read 3ft on right hand of the scale.

                    I supose partly cloudy is up to 50% (1~4/8).
                    For more details you can use the picker.

                                    What do you mean by "mostly sunny"?
                                    You are not covered by partly cloudy symbol?

                                          Firstly, I must let you know that I'm not Windy's personnel.
                                          So, I can't answer all of your questions.
                                          I don't know Windy's plans for the future.

                                          About sky condition, NOAA uses the following definitions :
                                          https://www.weather.gov/media/pah/ServiceGuide/A-forecast.pdf

                                          Turkish State Meteo. Service uses the following symbols:
                                          (cloud coverage in octas as I interpret them)
                                          793b6540-a613-43a5-8589-126518c305c9-εικόνα.png

                                          My question to you:
                                          What is the usefulness if Windy adds a "mostly sunny" icon?
                                          "Partly cloudy" is not enough?
                                          Do you think that the average reader
                                          can see any difference between the following icons?

                                          2d4b60ff-d0cc-41a0-92bd-d6640b334226-εικόνα.png
