On September 15, 2026, trader sentiment for rain-location markets hinged on official precipitation observations from stations such as CLIHOU in Houston and comparable NWS sites, with resolution turning on whether totals exceeded zero inches (trace amounts counted as zero). Most sampled U.S. climate reports for that date recorded 0.00 inches of measurable rain, consistent with a stable high-pressure pattern suppressing widespread convection and limiting activity to isolated orographic or coastal showers. Model consensus from earlier WPC medium-range guidance had favored dry conditions across the central and eastern U.S., aligning with final verification data released shortly after the event. Upcoming factors are limited now that the date has passed, though any late data revisions from NOAA or The Weather Company could still shift edge cases in multi-outcome markets.

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 KNYC: midnight to midnight local standard time. The final CLI report for a climate day is issued the following morning.
This market will resolve according to the NWS Daily Climate Report as published by 2:00 PM ET on the day following the observation date. If multiple versions of the report are issued, the last version published before that time 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 KNYC, published at https://forecast.weather.gov/product.php?site=NWS&product=CLI&issuedby=NYC.
