How to read this
- Market is the live price of each bracket on Polymarket, read as the crowd's implied probability that the outcome lands in that band. Bars deepen the further they sit from the model.
- Ensemble runs several weather models many times over with slightly different starting conditions. Each run (“member”) predicts a value; the shaded step is the (smoothed, model-weighted) share of members landing in each bracket — its height is the model’s fair price. A tight peak means the models agree; a wide spread means real uncertainty. The station has already reported 17.0°C today, so brackets entirely above that are ruled out (0%).
