@ivo Thanks for your swift reply. I know how go to settings, click "show historical data", choose the date in the calendar and then close it, then mark a coordinate of interest to show wind data on it, after I click the "play" video button and watch the animation, as the red time line bar shows progress through the days ahead. MY QUESTION really is HOW can I turn this animation (including the point of interest marker, if possible) into a video link that I can post in my facebook so that my friends can click "Play" and reproduce and see the same animation I saw on my own Windyty screen, in a similar manner to those videos or movies that you show on your own Windyty facebook. I am trying to help with a search and rescue operation for a missing sailboat that was caught in a storm and probable remained dismasted and adrift. Such a viedo/movie may help estimate the subsequent drift pattern od the drifting sailboat.
One good use for that would be a temperature outlook, because now I could use the arrow keys to view temperature on different days but on the same selected time. Whereas currently it's more useful if you want to see temperature in upcoming hours, not days. That's because it's hard to see the big picture because of temperature varying too much..
