Why several models?
Each weather centre runs its own model of the atmosphere, and no single one is always right. When the models agree, the forecast is more certain; when they disagree, the weather is harder to call, and it is worth watching the newer runs. The Lab's Forecast mode shows each model's maps, and Compare models sets them side by side for any place.
