We'd like to have our website display comparisons, so people can see how much more accurate we are than other websites. Not sure whether there are IP rules that would stop us from displaying someone else's forecasts though. Don't want to land in hot water for some simple summer project!
You could also let the user choose which model to use or show a comparison.
I'm doing something related and my next step is compare models vs current weather to see which I model is more accurate.
As models change and sometimes depend on current conditions this is something that you should never stop doing (comparing which model is better)
