Heavy rainfall concentrated across central Iowa on September 9, 2026, driven by a slow-moving frontal boundary that triggered repeated thunderstorms and flash flooding along the I-80 corridor. National Weather Service observations recorded 3–6+ inches in the Des Moines metro and surrounding areas, including record daily totals at Des Moines International Airport, with widespread 1–3 inch amounts extending into eastern Iowa and parts of Illinois. Elsewhere, most U.S. regions saw only trace or light amounts, while some eastern and southern locations remained dry or reported isolated showers. These verified NWS and cooperative observer reports form the primary basis for market resolution on precipitation thresholds and locations, with traders closely tracking official daily climate summaries for confirmation.

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.
