7 models, every run
Each of the major weather models' forecasts for every place we track, kept as each new run arrives.
Every forecast is a guess from one model. We show you all of them.
Compare
Where they agree, and where they split
When the models agree you can plan on it. When they split, we show the split rather than averaging it away.
Score
Checked against what happened
Once a day is over, each city's forecasts are scored against its own weather station, so you can see which model has been right.
