How to read: colored cells show whether each predicate requirement is met; highlighted rows mean the full rule matched (an opportunity). For OR groups, only one branch is required, so some OR-branch predicates can be ✕ even in a matching hour.

How this forecast is made
Opportunities are threshold-based signals: PhotoWeather checks whether forecast conditions match the rules for a photography scenario. They are planning guidance, not guarantees. Forecasts can change as new model runs arrive, and confidence generally decreases farther into the forecast horizon, so recheck conditions before travelling.
The weather forecast foundation comes through Open-Meteo , which aggregates models from weather agencies. PhotoWeather applies condition-specific thresholds and derived calculations; not every condition uses every model or data input.
