Observed Predicted Confidence band Camera index

Solid line: colour change reported by Ontario Parks, weekly, latest Aug 12. Dashed line: the ontariofall.com model, run Sep 1, with the confidence band widening as the forecast reaches further out. Green dotted: our camera colour index, inverted so less green reads as more colour and stretched across its own observed range, so read its shape rather than its height against the percentage axis.
