An upper-level low and associated frontal boundary are steering anomalously high moisture into the Midwest, Ohio Valley, and Great Lakes on September 20, supporting scattered to widespread showers and thunderstorms with locally excessive rainfall per the National Weather Service Weather Prediction Center outlook. Model consensus from the HRRR and RRFS indicates the highest probabilities of measurable precipitation (>0.01 inch) concentrated across eastern Iowa, northern Illinois, Indiana, and into the southern Great Lakes, with secondary chances expanding toward the Mid-Atlantic and Northeast as the system shifts east. South Florida also shows elevated thunderstorm risk tied to residual moisture. Official quantitative precipitation forecasts and updated model runs issued overnight will refine placement ahead of local climate reports used for market resolution, while soil saturation from prior days increases flash flood potential in the primary corridor.

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.
