National Weather Service observations for September 18, 2026, show measurable rainfall concentrated in the Upper Midwest, with Minnesota stations recording 0.55–1.49 inches amid widespread thunderstorms tied to a slow-moving frontal boundary. Southern Wisconsin and parts of Wyoming also saw showers or storm activity per local NWS products, while many East Coast and West Coast sites, including Washington DC, San Francisco, and Raleigh-Durham, reported trace or zero precipitation. Model consensus had highlighted elevated moisture and instability across the central U.S., consistent with the observed pattern of localized heavy rain and flood watches in Minnesota and Wisconsin. Traders monitoring resolution criteria should note that official daily climate summaries from NWS offices provide the verified precipitation totals used for market settlement.

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.
