@johnckealy Weather forceast model is a fascinating topic ! The more you use them the better you understand them, you know when one model can be more accurate than another, what model can or cannot do. IFS is probably one of the best model to predict the changes at synoptic level (1000 or 2000km) when Arome is capable to solve and calculates convection which can be useful to predict thunderstorms. Of course we can keep using one model only but Windy offers the possibility to easily compare the results from the different models so it is a nice and easy way to check the consistency between the models and therefore give you more confidence about the weather forecasts.

@Andrea-Perron – Yes I didn't cover ensembles in this article, but actually that might be a nice idea to cover in my next one. Thanks @Gkikas-LGPZ for that nice diagram. And special thanks to Ed Lorenz for being awesome and discovering Chaos theory :)
