This event tracks whether measurable rainfall will occur in various major U.S. cities on a specific date. Each location has its own market, and the outcome depends on official weather data confirming any precipitation beyond trace amounts.
Each market evaluates whether measurable precipitation exceeds zero inches in a specified U.S. city on September 23, 2026. Precipitation data must come from the Weather Company's official reports, with trace amounts or missing values counted as zero. All markets share identical evaluation criteria, focusing solely on the numerical precipitation total for each individual location without cross-market dependencies. The resolution hinges exclusively on verified meteorological records from the designated data source.
