Metadata and caveats
  • generated_at_melbourne: 2026-06-19T22:15:36+10:00
  • forecast_date range: 2026-06-19 to 2026-06-20
  • source: station-aligned Open-Meteo previous_day1
  • caveat: forecast update only, no odds/trading advice
  • caveat: cutoff_status is based on configured Melbourne trigger time
  • caveat: Rows marked STALE_FORECAST_DATE are for an older forecast_date than the current expected station-local target date. They are shown for audit visibility and should not be treated as current forecasts.
  • caveat: Rounded market bucket is the model forecast aligned to the market's whole-degree precision. Polymarket outcome is the actual displayed market bin/range containing that whole-degree value.
  • caveat: Conservative p is a heuristic lower-bound estimate from the probability haircut audit. It is not a true probability guarantee and is not a trading recommendation. Raw historical hit rates and conservative probabilities are math references only, before fees, slippage, liquidity, and execution risk.
  • caveat: Historical hit rate and Conservative p columns show the conservative display value. For exact + bucket rows, the displayed value is the lower of the exact and bucket percentages.
  • caveat: NYC / KLGA uses 2°F Polymarket range-bin outcomes. Its historical hit rate and Conservative p are computed against the actual range bin containing the rounded whole-degree forecast, not against a standalone exact 77°F market.
  • caveat: The prior NYC 57.53% bucket metric was tail-only and is no longer used for current range-bin display.
  • caveat: London / EGLC active market outcomes are exact whole-degree labels. Its displayed historical metrics use exact-number / rounded-bucket validation, not range-bin validation.
  • caveat: London MAX_THROUGH_19 range-bin recompute files are retained only as historical diagnostic artifacts and are not used for the active London frontend metrics.
  • caveat: Austin / KAUS uses Polymarket range-bin outcomes. Its historical hit rate and Conservative p are computed against the actual range bin containing the rounded whole-degree forecast.
  • caveat: Denver / KBKF uses Polymarket range-bin outcomes. Its historical hit rate and Conservative p are computed against the actual range bin containing the rounded whole-degree forecast.
  • note: This brief displays core tier-1 cities and new watchlist cities. Backend CSV/JSON outputs continue to refresh all configured live cities.
  • note: Core tier-1 cities are established live forecast monitors.
  • note: New watchlist cities are promoted from the new-city discovery audit and should be monitored separately before being treated as core.
