Forecast XL (multi-model)
This product displays data from several weather models for a given location. Because all the model data is displayed in one location, this product makes comparison easy. No one model is likely to get a forecast exactly right, especially 5-10 days out, but you can use this product to get an idea of general trends. If the majority of models are forecasting warmer temps in the 5-10 day period, you can reasonably expect warmer weather in the forecast even without paying too much attention to the individual highs/lows that may or may not be accurate.
You can also use this product to get an idea of the confidence models have in the forecast. If all the model lines are close together, that means that there is very little disagreement and you can have high confidence in the forecast. The opposite is also true and if you see the model lines diverge, that means the various models disagree with each other and thus the forecast becomes more uncertain.
