      Hi,
      Today there is no similar strange track. I have checked one or two tracks in the North Atlantic. They seem to correspond correctly to the max. gusts predicted in the same area once during the 10 days.
      A suggestion: sometime the track is due to a strong wind at day 8 or 9. For people it will be difficult to understand why they see this storm track if the strong winds are forecasted at near the end of the 10 days.
      So, instead to show the wind speed in the picker, may be it would be better to show the date when the max. gust is expected ?

            The ECMWF CAPE and thunderstorm layers are very different - e.g. massively high CAPE over parts of the UK but not much in the rain/thunder or thunderstorms layers. Does anyone know why these are so different? What goes into the the thunderstorm layer?

            Thanks

              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?
