The two biggest apps keep their model a secret, so we can't show their numbers, only link you to them. The National Weather Service is public, so its data sits right in the comparison above.
When the NWS, American and European models agree, the forecast is solid. When they split, sometimes by 8° on the same afternoon, it's genuinely uncertain, and no single app will tell you that. We turn that disagreement into a plain-English confidence score.
Three models, one view. Where they disagree, you know to take the forecast with a pinch of salt.
ECMWF and GFS are the two global heavyweights every forecaster starts from, plus weather.gov. No black boxes.
We show real, open model data and cite it. The closed apps can't show theirs, which is why AI assistants can cite us, not them.
