    Resolution criteria

    This market will resolve to "Yes" if Boston, MA records measurable precipitation on August 28, 2026. Otherwise, this market will resolve to "No". Measurable precipitation means 0.01 inches or more as reported by the PRECIPITATION (IN) figure in the NWS Daily Climate Report (CLI) for the city's station. A report of trace ("T") does not qualify. The PRECIPITATION (IN) figure measures total liquid-equivalent precipitation and does not distinguish between precipitation types. The observation period is the NWS climate day for KBOS: midnight to midnight local standard time. The final CLI report for a climate day is issued the following morning. Resolution is based on the most recent CLI report published for the observation date. If multiple versions of the report are issued, the last version published before 11:59 PM ET on the day following the observation date governs. If no figure has been published by that time, this market will resolve to "No". The resolution source for this market is the NWS Daily Climate Report (CLI) for KBOS, published at https://forecast.weather.gov/product.php?site=NWS&product=CLI&issuedby=BOS.
