consensus of the three models

7-day forecast

where the models agree, and where they split

The forecasts Americans check

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.

Every forecast runs on a model. We show you three, side by side.

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.

See the uncertainty

Three models, one view. Where they disagree, you know to take the forecast with a pinch of salt.

The models the pros use

ECMWF and GFS are the two global heavyweights every forecaster starts from, plus weather.gov. No black boxes.

Honest & sourced

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.
