Kalshi

Resolution is based on the minimum temperature recorded at Seattle-Tacoma on July 19, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS Western Region Climate portal by selecting Seattle-Tacoma, WA with the Daily Climate Report option.
