This set of markets assesses whether measurable rainfall will occur in various major U.S. cities on a specific date in 2026. Each market focuses on a different location, providing insights into regional weather expectations for that day.
Each market evaluates whether measurable precipitation—defined as strictly greater than 0 inches—will occur at a specified weather station in a particular U.S. city on September 17, 2026. Precipitation totals are sourced exclusively from The Weather Company's official data portal at weather.com/kalshi for the relevant station codes. Any recorded trace amounts or missing data entries are treated as zero inches and do not satisfy the 'greater than 0 inches' threshold. All markets share identical measurement criteria and data verification protocols, ensuring consistent evaluation across locations.
