We grade every model against the weather that actually happened, so you can see which forecast model is most accurate in United States before you trust any single number.

The models often agree on temperature and still split on rain, and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.
