          Dear All, Dear @Marienka
          may I ask the algorithm behind this new overlay? I'd like to use the same algorithm to calculate the type of precipitation in my country. I'm running WRF model for my research activities at the Iskenderun Technical University. Thank you very much for your response in advance.
          Happy new year to all.

            @Marienka How often is this overlay updated? It appears to be only hourly maybe?

              @esheesle It depends on the model, you check, and the plan you have. Premium is usually updated 4 times per day and you can check data with 1h step. Free offers 2 updates and 3h steps.

                In general, I like having this overlay, though I wish it were combined with Radar. However, my primary complaint is that "Rain" is colored as light blue, which is often associated as snow on many other precipitation type maps offered by other services. I would suggest changing the color of Rain to green to be consistent with other maps to avoid confusion.

                  The precipitation type map shows predominantly dark gray and white. Those colors are not in the legend, so may I ask what those colors represent? I assume the dark gray represents no precipitation, but when I look up the current weather in the white areas, no precipitation exists there as well. Freezing point doesn't seem to be a factor either. Thanks! Screenshot 2025-01-11 120440.png

                    White is in the legend even it is a sort of light gray to make the word “snow” in white letters readable.
                    Grey is where there is no precipitation. This is quite obvious.

                      @idefix37 Okay, thanks. I had a feeling the color shade was wrong in the legend, but when I looked up current weather in the white areas, it was not currently snowing in those locations.

                        What model did you use for Precipitation types?
                        Then are you talking about your own observations or the model snow forecast?

                          @idefix37 ECMWF and I compared it against a report from the Aviation Weather Center.

                            If you compare Precipitation type layer to observations, there is some chance that ECMWF forecast does not match these observations.
                            A prediction is not a report.
                            But this layer and the local forecast by ECMWF are consistent.
