Windy

What Windy actually is

Windy animates output from the major forecast models as flowing particles across a map, with layers for wind, rain, temperature, waves, pressure and air quality. You can switch between the European and American models to see where they disagree, and open a full meteogram anywhere.

Why it is worth your time

Swapping models mid-forecast and watching a storm track jump several hundred miles is the clearest demonstration of forecast uncertainty a non-meteorologist will get.
